One of the reasons that VPS hosting has become popular is to have a staging environment.  For instance, one private server could have the actual website or application and the other a copy of it.  If a critical update of the application or software needs to be made, the update may be tested on the staging server before committing any changes to a live production server. This permits testing before scheduling and performing maintenance and upgrades to a live production environment.

Expert Overview

Max Ostryzhko:
If you are just starting your website and don’t receive very much traffic, then shared hosting is the ideal solution. However, if your website’s audience is consistently growing, you’ll want to consider upgrading. You don’t want to run the risk of your website running slowly or, even worse, your server crashing because it can’t handle the traffic. If you anticipate an increase in visitors, do yourself a favor and switch to VPS.
Do you remember those times when you were living on a college campus with very noisy roommates? Or maybe they were super quiet and you enjoyed every day? The point is, it was a gamble - you never knew whom you ended up with. This is pretty much the same as having shared hosting account - you haven’t the faintest idea who is your roommate on a server. The analogy may sound funny but if someone on a shared server becomes a distributed denial of service (DDoS) attack target or get blocked for mass mailing, other accounts on the server will be affected as well. Also, if a shared account abuses server resources, the whole server will be impacted. Using a VPS is like owning a house with a 9 foot privacy fence. You won’t be bothered no matter what your neighbors are doing.
"Root" gives you administrative level access to edit, install and configure all of the files on your server, including system-critical files. It gives you ultimate access to your server. This gives you the ability to configure your server to your exact needs. While root access gives you full control of your server, it is intended for experienced users, engineers and developers. That's because you do have the potential to misconfigure or delete those system critial files if you're unfamiliar or inexperienced with what you're doing.
Cloud VPS is a type of hosting where multiple companies use isolated instances on the same host or parent server. This is perhaps the most common type of VPS hosting — when you hear someone talk about VPS, it’s most likely Cloud VPS. As you probably guessed based on the word “cloud,” another benefit is that you can access your Cloud VPS environments from anywhere.

Similarly, in a real dedicated server, you will pay for the entire server that is not shared with anyone else. You will get complete control over all services. Unfortunately, it is also the most expensive hosting option and needs some technical expertise to manage. It is commonly used by those who have websites with specific scenarios, most commonly extremely high traffic and tight security requirements.
Shared hosting is cheap and allows you to install any gallery platform you wish if a hosting plan meets its requirements. But be careful and study your hosting provider’s Acceptable Use Policy thoroughly. The truth is, that even if they claim unlimited storage with their plans, they don’t want you to use much of it. On the contrary, they secretly hope that you will use less and they can host many other clients on the same server. For that reason, hosting providers usually put limitations on their policies (e.g. “no more than 10 GB for images,” etc.). So don’t be convinced that you have unlimited storage without first checking your shared hosting provider's policies or you will find your account suspended someday.
Furthermore, due to the fact that bitcoin transactions take place almost immediately, you will also be able to skip the waiting period which is generally considered a norm while making online transactions. Furthermore, there aren’t any authorization requirements as well, thus saving you even more time.


I have used shared hosting for over 7 years before I finally decided to upgrade to a VPS server. When I was using shared hosting, I had so many problems with malware, slow loading time, brute force attacks and so many other issues. Now, my life is so much easier with VPS. What amazes me the most is the support team; they simply exceed my expectations and they are ALWAYS available to answer my questions.
Keep firmly in your mind the sort of assets that you require to serve your site(s) when seeking a host. Cost in a VPS is important, but not as key as you might think. VPS resource availability is scalable, so the cost that needs to be looked at is comparable cost from one host to the next. Also – as cPanel revised their pricing model recently, web hosting companies across the board will have to pass those costs on to users sooner or later. You will need to consider the cost of control panel when selecting a VPS plan. Companies like ScalaHosting has developed their own control panel to mitigate this issue – so their users would have little issues with the price hike.

VMware, Microsoft, Parallels, Citrix (Xen Server), IBM (Bluemix), & Red Hat (OpenShift) are all leading in providing enterprise data center solutions based on VPS networks under proprietary software licensing agreements. VPS web hosting plans are considered a performance upgrade between shared hosting and dedicated servers, where elastic web server frameworks like AWS E2 and Kubernetes also make extensive use of VPS/VM partitions in cloud architecture.

With VPS, you pay for what you use in the sense that you select a certain amount of bandwidth and storage to be allocated in advance. Scaling involves resizing your resources. But with cloud hosting, you pay for what you use in that your resource levels are not pre-determined, which means unpredictable pricing that tends to be more costly than VPS due to the overhead and complexity involved.


VPS hosting costs less and offers more flexibility than dedicated hosting, but semi-dedicated and dedicated hosting services offer more resources. VPS gives greater independence than semi-dedicated hosting though, because once again, the virtual servers on a single computer have no effect on each other and they are almost as reliable as a dedicated server.

So that’s it, then – a VPS is for everything in between, right? Well, yes…and no. A VPS (Virtual Private Server) is a flexible solution that falls in between shared and dedicated hosting, not only in price but also in the way it functions. Like a dedicated server, a site hosted on a VPS gets its own RAM and disk space; however, like a shared server, it uses the same processing capacity (CPU) as a certain number of other sites. So, while your site’s performance isn’t reliant on shared RAM and disk space, it is dependent on a shared processor. Moreover, the distribution of processor share varies from provider to provider.  The table below shows how most hosting companies break down the differences between shared, VPS, and dedicated hosting plans:
VPS hosting is like you are living in an apartment complex. It means that other people are living in the same building, but you have your own secure apartment. You will get more room and restrictions will be fewer as compared to living in a dorm. It also means that if your neighbour is misbehaving, it is the problem of owner of building, not yours.
Unlike managed VPS plans, unmanaged VPS plans are not actively managed by A2 Hosting. Unmanaged VPS plans are for more advanced users who are comfortable using the command-line interface and doing system administration tasks. These plans include root account access so you can customize the server as much as necessary. As a result, you are responsible for the following items:
Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS; however, due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.[2]

VPS hosting is a very scalable solution by its very nature. Virtual machines don’t depend on their physical server; as we have said, they don’t even recognize it exists. If a VPS needs to be upgraded or downgraded, all a hosting provider needs to do is to adjust the limits for this VPS in a hypervisor. After reboot a guest OS will work like nothing happened, using new hardware quotas. This comes in handy if you are not able to estimate the technical specifications you need before you run some tests. Also, if you have a seasonal business (e.g. you sell beach equipment), you can choose to have a more powerful server during your peak demand season and a cheaper one for the rest of the year.

However, if a bad user shares your server with you, they can threaten your security and allow hackers to easily reach your content and critical data. Furthermore, because you’re all sharing the same resources, if any of the users that you’re sharing your server with use a lot of memory or their site has a lot of traffic, your website’s performance is likely to suffer.
Think of a shared server as a large apartment complex, and all of the individual apartments are rented by other website owners. All of you need a place to live — just like your website’s files — but going out to buy a huge family home would be too expensive for your needs. Sharing common areas and utilities in an apartment block helps keep costs down. And the same is true for shared hosting.
Yes, VPS is a powerful and versatile type of hosting that many companies will find meets their needs. If you’re already hosting in a different type of environment, you may be wondering whether it’s worthwhile to migrate to VPS. This is an important discussion to have with each prospective hosting provider in order to understand how they handle migrations, what would be required from you, how long it might take, and any costs associated.


A VPS doesn’t just have more RAM, disk space, and a  proprietary share of CPU than a shared account. Depending on the provider, some VPS plans offer burstable memory, which is a pool of RAM set aside for extraordinary events. This is the stuff that can help counter the so-called “Digg-effect,” that much-whispered about occurrence that’s the simultaneous hope and fear of everyone who runs a web site. When you have an unexpected high traffic event, burstable memory will call on a pool of reserved, shared memory to satisfy the needs of temporary high traffic. This is not available on shared servers and, while the necessary memory is available on a dedicated server, your site might not get the kind of traffic on a daily basis to justify the expense of a dedicated server. Again, not all VPS plans have burstable memory, so ask your provider if their VPS plans do.
Any Forex trader uses special software called “trading platform” on a daily basis. A trading platform (a.k.a.“terminal”) allows placing orders, building charts, running Forex robots (i.e. Expert Advisors), and the like. In some cases, it is enough to install a trading platform on a home PC, for example, if you just learn about Forex and don’t make your living from it. Still, you need be 100% sure in your ISP and power supply, since anytime something goes down you may lose a trade. Or vice versa, make millions if your trading platform is ahead of competition.

And if your “neighbor” on the server is hacked, there’s little chance the infection will spread to your VPS because the hypervisors that are used to create separate VPS environments deliver multi-layered network security and keep tight controls on what enters and leaves. Your root access also means you can add or customize your VPS security software as you please.
