Shared vs. VPS vs. Dedicated: How to Choose?

Shared vs. VPS vs. Dedicated: How to Choose?

There is more to selecting the right hosting product than just pricing. In fact, basing your decision entirely on price is a recipe for disaster. When comparing prices on shared hosting vs. VPS, or VPS vs dedicated hosting, it may seem like a no-brainer to sign up for the cheapest option available, right?

thinking-about-shared-hosting-vs-vps-vs-dedicated

If you are running a web agency, you are not alone in thinking that shared web hosting, often as little as $5 per site monthly, is the most cost-effective solution for your business.

However, take a deeper look and you will quickly see how the financial, functional, and emotional benefits of a more robust plan from a managed hosting provider provides far more “bang for your buck” by giving you the performance, security, configurability, and scalability that you need to grow your business.

Not sure what server hosting solution you need for your business? Check out the core differences between hosting types to help you make the right decision.

What Do Shared, VPS, and Dedicated Server Hosting Mean

Before making an informed decision about what hosting type to choose, let’s first go over the definitions of shared hosting, VPS hosting, and dedicated server hosting.

What Is Shared Hosting? (Bronze Tier)

The most basic and cheapest of the hosting tiers. These plans allow you to rent space on a shared hosting server, which also hosts many other websites on the same server alongside your website. These plans are the cheapest solutions as they provide the least performance, security, and flexibility.

What Is VPS Hosting? (Silver Tier)

Virtual Private Server (VPS) Hosting is a cross between shared hosting vs. dedicated hosting. A physical server (also called the parent) runs several VPS instances, which are granted a strict portion of the parent server’s hardware resources. These instances are rented out and operate as independent servers from one another. So it’s essentially renting part of a dedicated server. These plans range in prices and offer affordable scaling, better performance, and security than a shared hosting website.

What Is Dedicated Server Hosting? (Gold Tier)

Dedicated Servers are exactly as the name implies: a single server dedicated to you. All the hardware that makes up the server is under your control. Dedicated servers often share network access with neighboring dedicated servers in a data center, but they share no hardware. These plans tend to be the most expensive but give you the best performance, security, and flexibility.

Each of these hosting products work in different ways. This means each will have its own strengths and weaknesses over the others.

How Do Server Hosting Solutions Compare?

Let’s compare shared hosting vs. VPS vs. dedicated server hosting by a few different metrics to see how we obtained this tier structure. This evaluation applies to products from any host, not only Diako.

chart-dedicated-vs-vps-vs-shared

Which Hosting Has the Best Performance?

Performance matters. If you want to keep your clients happy, you need to provide them with top-notch performance. A survey conducted by Kissmetrics discovered that nearly half of web users expect a site to load in two seconds or less, and they tend to abandon a site that isn’t loaded within three seconds.

Furthermore, 79% of web shoppers who have trouble with website performance say they won’t return to the site to buy again and around 44% of them would tell a friend if they had a poor experience shopping online. The bottom line here?

Literally, a second difference in page load speeds has the potential to lose out on revenue from frustrated visitors.

How do the three products stack up against performance?

Poor Performance – Shared HostingThese plans generally include very limited resources as they are granted only a fraction of the available system hardware. A shared hosting account holder can find themselves robbed of resources by other sites on the same server monopolizing the limited resources. The shared hosting tier is good for low traffic and static websites.

Good Performance – VPS HostingVPS plans are limited by the available hardware assigned to the plan. There is a performance tax on the hardware when running in a visualized setup. However, this tax has become smaller over time and provides more comparable performance levels to dedicated servers.

Great Performance – Dedicated Server HostingDirect access to the hardware provides the best possible performance configurations with a dedicated server.

Visualize Performance: The House Party Analogy

Let us consider shared hosting like your first apartment. It’s in a shared building with shared entrances, hallways, etc. Hosting a house party in your small two-bedroom apartment is very confined. You can easily invite too many people and start flooding the hallways with people and noise that will surely displease the other tenants in the building. The same holds true in reverse. If your neighbor throws a house party, you could be impacted by the ruckus. Your apartment works well, as long as you and the other tenants in your building respect one another and behave.

apartment-are-like-shared-hosting

Now you live in a duplex or condominium. This is more akin to VPS Hosting. You and your neighbors have more space and share less common areas. You or your neighbor can now throw a larger party than could be done effectively at your apartment. However, there are still limits and you still do have shared common areas such as parking. Your visitors will likely impact your neighbors, just to a lesser extent. But you do have more freedom in this space and your neighbor is less likely to be bothered by your party.

dedicated-is-like-owning-your-own-home

Dedicated hosting is like having your own house, complete with a big yard and extensive driveway. This provides plenty of parking for your friends and little chance that you or your neighbor’s party will get out of control affecting one another adversely.

As your party grows in size, it’s better accommodated and tolerated the further up the hosting tier you go. The party in the analogy is your site traffic.

The larger your traffic and number of visitors, the further up the tier you will need to go in order to accommodate the demands of your traffic.

Consider these questions as you pinpoint your business’s shared hosting vs. dedicated hosting needs:

  1. Will your clients’ sites have heavy or highly variable traffic?
  2. Do you need to minimize downtime or guarantee high availability?
  3. Do you want control over your server and its performance?

If none of these issues sound important to you, you might be fine on a shared hosting plan. If you answered “yes” to any of the above, consider VPS or dedicated hosting.

Traffic Volume

The amount of bandwidth in and out of your server is one consideration. Inbound bandwidth is usually less important than outbound bandwidth because unless your visitors will be uploading a lot of data, inbound HTTP requests will be small in size compared to the documents and images that your site will return for each page request.

Shared hosting platforms are usually not set up for high volumes of traffic and processing since the power of the server must be distributed between dozens, or sometimes hundreds or thousands of other users and websites. But, for average sized and trafficked sites, such as hobby sites or “pamphlet” information-only domains, or even small blogs, shared hosting is perfectly acceptable. Sites that require more intense server-side functions, like online stores or sites which generate documents such as invoices or quotes, or sites which convert audio or video on the fly, may need more resources allocated than would come with your average Shared hosting account.

Additionally, sites which have higher outbound bandwidth, like those that serve up audio or documents to users, will need additional bandwidth (and disk space) that shared hosting may not provide, and a VPS would be better in those cases.

What Server Offers the Most Security?

While Risky Business was big in the 80s, business today is all about minimizing threats. When comparing shared vs. VPS security, the differences become clear very quickly.

Can you afford the risk of a client’s site being hacked? As a business owner, in addition to the costs of downtime and repairs for a client’s site going down, your reputation is also impacted, which is a much more serious and permanent problem.

Consider the following security summary for each type of hosting before you decide what is right for your clients.

Low Security – Shared HostingThe activities of other sites on the server can affect your clients’ sites, putting them at risk of viruses, hacking and blacklisting. The more domain names pointed to your shared server’s IP address, the more often it is targeted for an intrusion.

Good Security – VPS HostingEach user occupies their own space, isolated from their neighbors with independent IP addresses. Rarely, a virus may bypass the hypervisor, which could leave all sites on the VPS server vulnerable.

Best Security – Dedicated Server HostingBecause you are the only one using the dedicated server, risk of attack is minimal. There is more to selecting the right hosting product than just pricing.

shared-hosting-vs-vps-vs-dedicated-offer-different-levels-of-access-to-the-hardware

How Is Hosting Configurability?

This metric is a gauge on how much control the user has over the server and their environment on that product type. The differences between shared hosting vs. VPS/dedicated servers vary greatly, but not so much when looking at VPS vs. dedicated.

Highly Restricted – Shared HostingEach user is highly restricted in their own environment. Customization is limited to surface level changes such as .htaccess, PHP versions, Specific List of Modules. There is no access to any service or server level configuration.

Mostly Unrestricted – VPS HostingThere are very little restrictions on a VPS. Each environment is separate from the others on the server and acts exactly like a dedicated server with a few off-limits configuration. Direct access to hardware being the biggest restriction. This prevents running hardware emulation within the VPS and accessing non-network attached storage devices.

Unrestricted – Dedicated Server HostingDedicated servers can be configured anyway you choose with no limitations or restrictions from the host. The user has direct access to the hardware.

Controllability

If you need to have specific software installed, or need special configurations on your server, it could be uncommon to find a shared hosting package that includes exactly that feature set. (though it is common to find hosting providers that will already have installed popular software, like FFMPEG or ImageMagick) And, it would also be unlikely that your host would install a special package for you on a shared machine, which could pose a security risk to other tenants. Therefore, a shared hosting package would have low controllability.

A VPS, on the other hand, gives you complete access into your system, so that you can enable, disable, install, or remove any software you wish, and adjust configurations exactly to your specifications. So, you aren’t restricted to the software that your hosting provider gives to your environment.

scalability-differs-greatly-between-shared-hosting-vs-vps-vs-dedicated-hosting

What Determines Scalability?

The scalability score measures how difficult it is to scale the product resource limits. The more difficult the scalability, the lower the score. Versatility and turn-around time also play a role in scaling, which differs between different web hosts.

Limited – Shared HostingShared server packages are generally not very elastic. The user is confined to a package which allows specific limits based on bandwidth, disk usage, and other factors depending on the hosting provider. This package can be changed up or down depending on the needs and price-point, but scaling upward is limited due to division of resources among shared users, which forces migration to a new server or product type. Options for changing the resources on your package generally include increasing your disk quota, and in some cases, removing limits on your CPU access.

High – Dedicated Server HostingDedicated Servers are limited by the physical hardware and space in their chassis. Upgrades are always possible and may require significant downtime or migrations depending on the needed upgrade. Server Clustering and High Availability solutions can limit this but generally have a much larger price point.

Very High – VPS HostingVPS systems are extremely flexible in scale factors. VPSs will have more functionality available for adding or removing resources, including CPU cores, system memory, and additional disks or disk space through your hosting provider. They are only limited by the available hardware on the parent server. However, they are generally portable between like parents so they can be easily moved and upgrade with minimal downtime and turn-around time for upward scaling.

Resource Availability

A shared hosting package is, of course, shared amongst multiple occupants. Therefore, if you have a “noisy neighbor” who is overusing CPU time or eating up memory, then there will be less available for the remaining websites, including yours, causing them to suffer in performance.

Modern shared hosting providers will combat this by introducing resource limitations, such as maximum RAM usage, maximum number of processes, and maximum CPU percentage. These work to combat the “noisy neighbor” problem but could limit you from temporarily overusing resources to run, say, statistics, or compile your nightly order list. Being able to temporarily break these shared resource limits is called “bursting,” which is an option for some hosts.

There are “virtual dedicated” packages available at some hosts which provide all of the resources on one parent (dedicating it to your VPS) to avoid noisy neighbors but retaining the hypervisor’s scalability and management.

pricing-between-shared-hosting-vs-vps-vs-dedicated-hosting

How Does Pricing for Hosting Work?

The simplest metric that should not be overlooked when deciding which hosting platform works best for you is pricing. The costs summarized here includes monthly incurred charges and potential costs of upgrades.

Lowest – Shared HostingShared Hosting packages are very low-cost due to their nature. Shared servers are often banking on overselling their hardware, which means more users reside on the server than a server can handle if all users were fully active. This allows small sites to be packed in around busier sites reducing monthly costs needed to recoup the cost of the server.

Mid to High – VPS HostingVPS solutions come in many forms, from the smallest 2GB VPS, to massive 128 core machines. VPS Parent servers are often built from the very best hardware available at the time to offer the most varied amounts of configurations for users.

Highest – Dedicated Server HostingHands down, these servers will have the biggest costs, in both monthly recurring fees and hardware upgrades. This is a result of paying directly for the hardware you are using and not piggy-backing off of a larger hardware set used for VPS configurations.

What Are the Differences Between Each Server?

We’ve gone over general benefits of each hosting type: shared hosting vs. VPS vs. dedicated servers. However, this doesn’t tell the whole story. Let’s get a bit deeper with some one-on-one comparisons.

What Is Shared Hosting vs. VPS?

Shared hosting setups are a single server environment with multiple users. As a shared hosting site owner, you make up merely one of the many other users on the same server. This model relies on locking down access and permissions to all users so they can only operate within their personal environment. However, all the libraries and software binaries are shared between users. This not only limits the software a shared hosting account is allowed to use, but opens the door for possible intrusion from other users looking to exploit the system.

On the other-hand, VPS are a completely isolated environment separate from other users on the server. This environment acts exactly like a stand-alone server. This gives the owner the freedom to install and configure any required software without interfering with, or interference from, the software installed on another VPS running on the same parent server.

What Is a VPS vs. Dedicated Server?

While VPS servers function similar to dedicated servers, VPS does have limits and other differences from dedicated hosting, including:

VPS Hosting

The VPS product does not have direct access to the hardware on its parent server. It is running in an emulated hardware environment which prevents certain software from functioning. For example, a VPS cannot run hardware emulation as it requires direct access to hardware and is restricted to only the parent server. You cannot emulate a VPS within a VPS.

This hardware restriction aside, there is very little software a VPS cannot run. They can even be configured to be comparable in performance to a dedicated server that has matching hardware. The big selling point for VPS is scalability. Since the hardware environment is emulated it can be modified on the fly and, in most cases, without any downtime. So if the 8GB of memory on your VPS is not enough, you can easily upgrade to 16G without having to take the server offline and add the new RAM physically. Isn’t virtualization beautiful?

Dedicated Hosting

Dedicated servers can literally do anything when it comes to hosting solutions. They are what make up the backbone for all internet hosted sites or application. In some form or another, all software has to run on physical hardware so there really is no limit to what can be done with dedicated servers.

You can even use a dedicated server in conjunction with other dedicated servers to setup clustered or high availability services to prevent or reduce downtime during critical hardware events.

A single dedicated server can be used as a parent server to multiple VPS servers running hardware emulation and those VPS instances can be moved between similarly configured multiple parent servers to allow for more/less hardware as needed. Dedicated servers provide total control over your hosting environment.

What Is Shared Hosting vs Dedicated Hosting?

Comparing shared hosting vs dedicated server hosting is effectively identical to Shared Hosting vs VPS. Dedicated servers offer even more control over the environment than a VPS but inherit all the same strengths and weaknesses. Additionally, Shared Hosting servers are typically made from a dedicated server or cluster of dedicated servers. Inherently, dedicated servers have more ability to scale, perform better, and provide more protection from attacks. The only downside is the price point.

What Are Shared vs. VPS vs. Dedicated Servers?

When considering shared hosting vs. VPS vs. dedicated server hosting, each one falls into their own niche of use cases. Their differences and their strengths compliment their intended use.

Shared Server Hosting

Shared hosting is the lowest in cost, least-configurable, least-scalable, least-secure, and lowest-performing solution. However, it works well for small businesses or individuals without much budget, students, and other users looking to get started in developing their own website.

VPS Server Hosting

VPS solutions are moderately priced in comparison to shared hosting or dedicated servers. They come with full access to their own environment, mostly isolated from others which increases security while reducing potential downtime from neighbors on the same server. VPS solutions are also highly scalable and can be upgraded and downgraded as needed due to their virtualized hardware. This makes them excellent as both production and development environments can house most websites and applications while still providing great performance.

Dedicated Server Hosting

Dedicated servers are premier hosting solutions. They can be setup and configured in almost any capacity to handle the needs of any website or product. Dedicated servers can be custom built and allow unlimited access to the hardware, making anything possible on your dedicated server. The hefty price tag comes with the best possible levels of performance, security, scaling, and configurability.

Managed-Hosting

What Is Managed vs. Unmanaged Hosting?

Now we have compared three different hosting tiers: shared hosting vs. VPS vs. dedicated hosting. But, there are actually five options here for you to choose from. While shared hosting is always managed (albeit without many of the services that are associated with managed plans), VPS and dedicated hosting come in two flavors: Managed or unmanaged. This effectively doubles your options.

So… now how do you choose?

Try not to underestimate managed solutions. Most managed hosting solutions solutions come with a more robust support structure. The cheaper shared hosting plans will typically offer basic technical support, but not much above and beyond that. There is immense value in having access to a full team of experts, like The Most Helpful Humans In Hosting®, who have specifically tuned your server for the idiosyncrasies of hosting and securing your clients’ websites.

The decision between managed and unmanaged hosting will come down to how much work you are willing or able to put into managing your own servers. Ask yourself the following questions when determining between managed and unmanaged hosting:

  1. Am I willing to maintain software updates?
  2. Am I ready and able to research and apply security patches to patch up software vulnerabilities?
  3. Am I able to troubleshoot unexpected problems?
  4. Am I available 24/7/365 in case my website suddenly goes down?

If this is an undertaking you are incapable of handling or don’t have the staff on hand to keep up with your growth, then managed hosting is certainly right for you.

Unmanaged Hosting – A Cold ShoulderIt varies by provider, but in most cases, unmanaged server providers offer little to no effort with troubleshooting. They will typically help with things that are out of the server’s control, like network, hardware, and power problems. But you’ll be on your own when it comes to configuration, optimization, routine maintenance, and more.

Managed Hosting – The Friend Next DoorProviders offer a myriad of helpful services to their managed customers in addition to those that an unmanaged customer would expect. They can render easy assistance by providing base configurations for your site or application. You can even get assistance with the day-to-day sysadmin tasks like migrations, scaling, backups, disaster recovery, monitoring, updates, and maintenance.

What are the Benefits of VPS Hosting?

What are the Benefits of VPS Hosting?

Wondering what the benefits of VPS Hosting are for your business?

Every business today is striving to gain market share, customer base, and see overall growth. And one of the best pathways is to ensure your development cycle is lightning-fast.

Businesses that see an online presence as a necessity are looking to quickly develop their site, update frequently and stay ahead of trends.

For the developer looking to quickly and efficiently start a project, mock-up a site for a client, or administer the online component for a company, nothing beats the ease and speed of Virtual Private Servers (VPS).

A VPS server is the perfect tool if your team is looking to start a new project, quickly test out an idea, or have a sandbox/playground to try new technologies.

Below I’ll talk about the five benefits of using a Virtual Private Server for your next project:

  1. Speed of machine creation
  2. Ease of growth/expandability
  3. Cheap cost/low barrier of entry
  4. Snapshotting/backups
  5. Add-ons and additional features

But first, what is VPS Hosting?

What is VPS Hosting?

Virtual Private Server Hosting, or VPS Hosting for short, is a virtualized hosting solution with specific memory, space, and CPU cores allocated to a single-tenant, and is located on a single parent server or cluster of parent servers.

It is one of the most instantly scalable and affordable web solutions available on the market today, and needs to be strongly considered for your next web project vs Dedicated Hosting.

VPS

The Five Benefits of VPS Hosting

1. Speed of Machine Creation

Dedicated servers are custom built by hand from individual components that a customer specifies. This is a slow process that requires communicating with your account manager, the delivery team, and the time necessary to actually build and deploy the server.

One of the most significant benefits of using VPS Hosting is that virtual servers can be deployed within minutes with the click of a few buttons.

This puts you in the position to get started on your projects faster, present your creation to clients sooner, and profit from the increase in business you can generate by not losing out on time waiting for a server to be built. All of this is possible due to the nature of virtual servers: pre-built machines with pre-defined specifications waiting to be activated.

You may think that due to their being pre-built/pre-specified that you will have limited options; the exact opposite is true. Virtual servers today are extremely flexible and offer numerous options/customizations on-demand, such as:

  • The amount of memory (RAM) needed
  • Hard disk space required
  • CPU cores allotted

That is why VPS Hosting is so easy to expand and scale as needed.

Ease of Growth and Expandability

2. Ease of Growth and Expandability

One of the most frustrating parts of a business is being unable to keep up with the growth needed to satisfy customer demand. With traditional dedicated servers, if you need to increase the amount of memory or disk space, you face long delays while communicating your needs, downtime while the hardware is upgraded, and potential issues with your site or project if data migration is required. Upgrading CPUs may even require full chassis swaps, which can cause even more delays and downtime.

The main difference between VPS Hosting and Dedicated Hosting is that VPS Hosting allows you to increase memory, disk space, or add CPU cores almost instantly with the click of a button.

As your traffic and business grow, you are able to quickly and easily alter the specifications of your server to keep up with the increase in traffic.

You may think that all of these features and automated components are going to make this virtual technology more expensive, but the very opposite is true. VPS Hosting is much more affordable than Dedicated Hosting.

Affordable and Low Barrier to Entry

3. Affordable and Low Barrier to Entry

One of the major benefits of utilizing VPS Hosting is the reduced cost for getting your project off the ground.

By their nature, a VPS Server is cheaper than a Dedicated Server due to shared hardware components and lack of manpower needed to get them running. These cost savings get passed on to you, which enables you to provide a lower cost to your clients.

This also means that if you’re looking to test out new technology, have a testbed machine with which you can experiment, or a staging area for client sites, you can easily use a VPS without worrying about the cost skyrocketing and being a financial drain.

You can choose the OS you want and the level of support management up front, and within minutes you can be online with root access, able to begin developing your application, uploading files, and getting your project online.

All of this can be handled directly within the control panel used to create your VPS and requires no interaction with another human, no delay in getting hardware assembled, or software installed.

When you need to be online as fast as possible, the fastest option is a VPS.

But simply getting online quickly is not enough. You need to be sure that what you’re working on is safe, secure, and your time not wasted.

That’s where backups and snapshots come into play.

Snapshotting and Backups

4. Snapshotting and Backups

Nothing can be more detrimental to your online business than your site being inaccessible. There are a large number of concerns when hosting your project that can bring your online presence offline: malware and viruses from hackers, incidental hardware failure, or human error when changing or altering files. Any time offline or correcting mistakes is a potential loss in earnings and reputation.

Another benefit of VPS Hosting is that it makes automated backups as easy as the creation of the server itself: point and click.

Scheduling backups, retaining multiple backups, and restoring from them is fast and simple, ensuring that even in the worst case scenarios, your data can be protected.

Backups are stored on remote servers, physically separated from your virtual server so that even physical hardware malfunction doesn’t cause you to lose data. All of this is performed behind the scenes without you worrying about what is taking place, so you can spend your time focusing on the project at hand.

Also, simply backing up your data is only one factor that virtual servers have simplified. A virtual server allows you to easily create a base “template” or snapshot for a server that you would like to use repeatedly. You can then save this template and create new servers based on it at a later date. Just be wary of changes that were made after the snapshot was performed.

If you need a server for a short period of time you can save the server as an “image” for reuse later on, or you can create a server multiple times for different projects or splitting traffic in a load balanced environment. These snapshot features allow you to quickly create consistent servers and ensure that your environment is configured exactly how you need it for the project you’re working on.

Add-Ons and Additional Features

5. Add-Ons and Additional Features

The driving component of virtual servers is the automation behind the scenes that allows them to be easily created, altered, and destroyed. This automated nature means that we can easily tie in additional services by using the same point and click concept, making it easy to add these features to a virtual server.

Being able to quickly add a load balancer in front of your servers, configure a firewall for single or multiple machines, maintain control over your public IP addresses for use between machines, and even create a private network for use with only your servers are all possible.

That’s not all though. VPS can also include:

  1. Built-in monitoring of your server’s health
  2. A connection from your servers to object or block storage pools
  3. A history of tasks and changes

As new products and features are created, they’re easily added and integrated into your virtual server thanks to the automation of how they work. Automation is why VPS Hosting is chosen for web projects, time and time again.

Whereas traditional dedicated servers need additional software updates or production impacting software updates, virtual servers are easily able to adapt and update to take advantage of the latest technologies.

Virtual Servers are Here to Stay

Virtual servers are a mainstay product in the hosting world for development.

The cheap cost and ease-of-use are the primary benefits for individuals looking to get projects off the ground quickly, but the automation and add-ons make VPS Hosting a fully-featured hosting solution for growing SMBs in 2020.

Still Undecided on VPS Hosting vs Dedicated Hosting?

What is VPS Hosting?

What is VPS Hosting?

VPS hosting is an available option for both shared servers and dedicated servers. With many acronyms describing service offerings and virtual server types, it can be difficult to really know what you are getting when you purchase a service or resource to host your website.

VPS hosting is an excellent platform for personal websites, small-to-medium-sized business websites, or eCommerce marketplaces. To ensure that you make the right decision for your situation, start by diving into what VPS hosting service offers and whether they are a good fit for your needs.

What is VPS Used For?

Beyond hosting a website, VPS servers have a myriad of other uses. Even if you’re currently happy with your existing hosting plan, you might want to check out VPS hosting for the other types of scenarios it provides.

Here are the most common VPS use cases beyond your standard hosting plan:

1. Hosting Your Own Personal Server

There’s a multitude of reasons to run your own server environment, outside of simply hosting your website. A VPS server gives you your own virtual playground for additional online activities.

For example, maybe you want your own dedicated servers for games? For some people, the cost of a dedicated server might be prohibitive, but instead, you could run a VPS server to host smaller game matches or create your own custom game environment.

Not every hosting company will allow you to run a gaming server via VPS, so make sure you read the terms and conditions, or contact support, before you decide to go this route.

2. Testing New Applications

If you regularly deploy web applications or test out custom server setups, you’ll need your own server environment to test these things out. But, an entire dedicated server might be too expensive to warrant simple testing.

In this case, a VPS will fit the bill perfectly. This will give you a playground to do whatever you wish without incurring high monthly costs.

3. Additional File Storage

Sometimes, you want to create another backup of your files, but using cloud storage accounts can become expensive. If you want to create secure and easily accessible backups, then consider using a VPS server. Overall, this might end up being cheaper than a cloud hosting account, depending on the overall volume of the files you need stored.

However, keep in mind that not every hosting provider will allow their VPS accounts to be used for pure file storage, so double check the terms and conditions before you move forward.

What Does the VPS Provide?

VPS is short for virtual private server, sometimes referred to as virtual dedicated server (VDS). As a client of a web hosting service, you are provided access to a virtual server. This means that many virtual servers are likely operating on one physical machine within the hosting service, and you are granted remote access to a piece of the whole.

As the end user, it appears as though you have your own dedicated server. VPS services allow you to install your own security software and configure it with the operating system of your choosing. However, in reality, you have just a portion of the server, which is also being used by many other customers.

What Can Be Run Using VPS Hosting Services?

Because a VPS is analogous to a virtual machine, any software that can run on the VPS’s operating system may be installed. For example, a VPS can be used to support any of the following:

  • eCommerce software
  • blog hosting
  • company website
  • file transfer protocol (FTP)
  • email server
  • data storage

The Benefits of VPS Web Hosting

There are benefits and drawbacks to VPS hosting services. While many customers will not notice any decline in performance over the long haul, some larger websites may experience decreased performance due to the activity of the other users on the same server. For many businesses though, VPS hosting offers up all the benefits they expect at a reasonable cost. The four main benefits of VPS web hosting are as follows:

1. Flexible Resource Allocation

VPS hosting offers dedicated resources for your website; specifically, the amount of RAM, CPU, and disk space you specify are assigned to your VPS. If, however, your website experiences a surge in traffic and requires greater resources than you have specified, you may be able to temporarily borrow resources from another VPS.

The flexibility permitted by the VPS is one of its most useful benefits. VPS hosting often makes use of a hypervisor, which is software that facilitates this sharing of resources. If your site needs more resources to accommodate a large number of visitors and another website on a separate VPS is not using all of its resources, your site can borrow the extra power.

2. Root Access to Customize and Configure the VPS

VPS hosting also gives you root access to configure and make changes to your hosting environment. Root access is not guaranteed with other arrangements, such as a shared hosting plan. If you are particularly tech-savvy or foresee hiring web developers in the future, the root access will allow you to configure your VPS accordingly.

A common alternative to VPS hosting for website owners is dedicated hosting, where you do not share the server with other customers. Dedicated hosting is a popular option because of its root access and improved configuration. VPS hosting, on the other hand, allows you to enjoy the benefits of customization that a dedicated server offers without the large price tag..

3. Scalability

As stated earlier, VPS hosting is the middle ground between a shared server without any dedicated resources and a completely dedicated server with optimum performance. Most websites perform adequately with VPS hosting and only require slight increases in performance as the site and traffic grows.

VPS hosting offers scalability so that available resources can grow with you as you need them. This means that if you start out on a shared server, you would then need to invest time in migration to a VPS when required. However, if you start with a VPS, you can migrate slowly without breaking the bank on a dedicated server, which you may not need for quite some time.

4. An Affordable Option

VPS hosting is much more affordable for website owners than purchasing a dedicated server. It can reliably host your website or application, handle surges in traffic, and grow to accommodate your needs over time.

Rather than committing to a dedicated server and spending nearly twice as much (or sometimes more) than a VPS hosting solution, take your time to evaluate your options. VPS hosting offers you a way to get in the game without a prohibitively high cost of entry.

The worst thing that could happen if you end up needing a dedicated server in the future is that you would need to spend some time and money migrating to that upgraded resource. However, you would still have saved money in the beginning with a VPS server and learned which features are appropriate for your application or website.

Look into Your Options Before Investing in VPS Hosting

In addition to reading blogs and doing your online research, call a couple of trusted providers of VPS hosting and ask for their opinion on which type of hosting best suits your current needs. You might be surprised to learn how affordable a monthly VPS hosting plan is for your current needs.

Prepare for your conversation with possible hosting partners by knowing your budget upfront and having key stats ready to help inform your decision. Make sure to check your current (or predicted) site traffic and note any times in the recent past when your site was down or experienced poor performance. You should also know what you want out of your hosting platform, whether it is better reliability, increased performance, or room to grow as your traffic increases.

Do You Need to Use VPS?

VPS hosting is a perfect fit for those who require the resources that a dedicated server can provide, but aren’t quite ready for a dedicated web server.

When it comes to your website, using VPS hosting will offer you higher levels of performance, storage, and scalability if the need arises.

However, you might also think about utilizing a VPS for deploying and testing projects, running your own personal server, or even for additional file storage or website backups.

Whether or not you need to upgrade to a VPS depends on if you’ve currently hit the limits of your existing hosting package, or want to test out a VPS for any of the reasons highlighted above.

Hopefully, you have a better understanding of what a VPS is used for, even beyond the realm of hosting your website. If you’ve currently hit the limits of your shared hosting account, then upgrading to VPS hosting can be a great decision for the future of your website.

Once you have a few conversations under your belt with VPS provides and are armed with a range of features, applications, and pricing, you’ll be well equipped to decide if VPS hosting is the best type of hosting for you.

What is MongoDB?

What is MongoDB?

MongoDB is a Document-oriented database. And is in the NOSQL database group.

In this type of database, there is no table and record and collection and document are used. It can be said that the set looks like a table and the document looks like a record in a relational database.

In this database, the data does not have a fixed structure, and both documents (similar to a record in a relational database) can have a completely different structure, this type of structure is called a BSON. For example, two documents from an entity in this database might look like this:

Document 1:

id_ – name – age

Document 2:

id_ – family

What is BSON? MongoDB stores data in json format. This structure is called BSON in Mongolia. The structure of BSON is as follows.

{
"_id": ObjectId("b7d284dad1058f5698gorjhdc"),
"Name": "sepehr",
"age": "36",
"Date of Birth": "21/05/85",
"address": {
"city": "Toronto",
"PostalCode": "M1E5tx"
},
"phoneNumber":[
{
"type" : "Home",
"number": "64895555"
},
{
"type" : "work",
"number": "0155853600"
}
]
}

One of the advantages of MongoDB database over other relational databases (such as MySQL) is the ability to process and search much larger volumes of data at a time, as well as the ability to store larger volumes of data.

SQL to MongoDB

Higher processing speed: The relational database in each search or in each data store must examine many conditions such as the relationships between tables and the accuracy of record values, which greatly increases the RAM and CPU overhead, while MongoDB due to the NOSQL structure only It stores and searches, and as a result, the speed of accessing and storing data is drastically reduced.

Higher data storage: Databases can increase the amount of data that can be stored in the system in two ways. horizontal-scaling and vertical-scaling.

1. vertical scaling: In this method, the data is stored on a node and to increase the data volume, we increase the RAM and CPU or Hard Disk (hard disk). One of the databases that use this method is MySQL.
2.horizontal-scaling: In this method, the data is distributed on different nodes, and each piece of data is stored on one server, thus the processing load will be distributed on different servers and the speed of data access and the amount of stored data will be increased. Databases that use this method can be called MongoDB and Cassandra.

MongoDB structure

As mentioned above, in MongoDB you can master the amount of data that can be stored as well as the speed of data access by mastering horizontal-scaling called shard.

Advantages of using shared:

  • As the cluster expands, the number of processes that each shard performs decreases (due to the spread of processes between the shards), thus increasing the speed of data access.
  • As the number of shards increases, so does the amount of data that can be stored.

Install MongoDB as a shard

 

MongoDB spreads data across the collection. This means that the data of a set is distributed between nodes and shards. MongoDB uses the shard key to manage how data is distributed. shard key is a simple key or a combination key that is present in all documents. Generally id_ can be used as a shard key.
MongoDB uses two types of shard keys to distribute data. range based partitioning and hash based partitioning.

To study: What is Docker?

  1. Range Based Sharding: In this method, the data is stored as a shard key in categories called chunk. As a result, data with a shard key will be stored close to each other in a chunk. The advantage of this method is high search speed when we search by key. And the obvious problem is that the data is not properly distributed in the chunk. Since the data is generally stored in the database in key order, and because the input data to the database is in sequential key, all data will be stored in a chunk series.

2.Hash Based Sharding: In this method, Mongo generates a hash from the fields and then distributes the data in chunks using these hashes. Because the hash generated by the keys is completely different from the key, two documents with equal keys may be in two completely different chunk.

Hash Based Sharding

Hash Based Sharding

In this method, unlike the Range Based Sharding method, the data is completely distributed in chunks, so the processing pressure will not be on one node. One of the disadvantages of this method is that unlike the Range Based Sharding method, it is not easy to quickly search the data of a range.
