When it comes to web hosting, you have three main choices: shared hosting (the cheapest and most popular option), a dedicated server that is entirely yours, or a crossbreed of the two that allows you to have all the power of a dedicated server at a lower cost. This solution is called a virtual private server (VPS).
What Is a Virtual Private Server (VPS)?
A virtual private server (commonly abbreviated to VPS) is created when a physical server is divided into smaller, virtual compartments. Just like a dedicated server, a virtual private server has its own operating system, dedicated storage, and dedicated RAM and CPU resource but it costs much less than a dedicated server.
The Difference Between Shared, VPS & Dedicated Server Hosting
Shared hosting is like staying in a dorm with a group of other friends. You all fit into one dorm, and because you’re all splitting the cost between you, it’s cheap and affordable. However, because of the number of individuals sharing a space, your security can be compromised, and you only have a limited amount of space.
Most website owners use a shared hosting service, which is when your site shares a physical server with many other websites. Shared hosting was created for smaller sites because it’s cost effective and easy to use. You don’t need technical skills to manage your hosting because your hosting provider takes care of your server’s maintenance.
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.
VPS Hosting is like living in an apartment complex. You have a few other people living in the same building as you, but you have an entire apartment to yourself with more room and fewer restrictions than you’d have in a dorm room. If a neighbor living in another apartment is misbehaving, you won’t usually have to deal with them.
Although a number of VPS users share a server, they’re isolated from each other, so even if a bad user shares the same physical server as you, they’ll have no impact on your VPS service. This is because your data is secured and isolated from other customers. Each VPS user has their own server resources to use.
A VPS will only cost a fraction of an entire server, so it’s perfect if you need the benefits of a private server, but don’t want to pay a lot.
A Dedicated Server is like owning a house – you’ve got as much room as you could possibly need. But now you have more bills to pay and an expensive mortgage, too.
Dedicated server hosting is when you rent an entire server that’s not shared with anyone else. You have full control over the server including choice of operating system, hardware etc. This is the most expensive choice and is mostly used by users who have high profile websites or higher data needs than the average user.

7 Signs That you Need to Upgrade to Virtual Private Server (VPS) Hosting
Being a web hosting provider, we have had many customers over the years who found that they needed to upgrade to VPS hosting. Below are the most common situations which led to an upgrade. If you can relate to any of them, you’re probably ready to switch to VPS hosting.
1. Your Website is Running Frustratingly Slow
The more content you add to your website over time, the slower it will run. There are often a few causes for this common problem, but there’s a good chance that your site is slow because you’ve finally hit your shared hosting limits. In order to boost your site’s speed, it’s a good idea to upgrade from shared hosting to VPS hosting to decrease page loading times.
2. You Have a High Amount of Traffic
When your website starts to gain more popularity and web traffic to your website increases, your current web hosting plan may no longer be capable of handling such large amounts of traffic. A virtual private server will be able to handle much higher levels of traffic than shared hosting.
3. You Often see the Dreaded ‘50X’ or ‘Internal Server Error’ Message
Has your website ever displayed a 50X error (508, 503, 504, 507)? This could mean that your site has maxed out it’s allocated resources available on your shared server. For access to more resources, you can either try to upgrade your shared hosting plan or switch to VPS hosting
508 ‘Insufficient Resource’ Message
4. Your Site Contains Data Sensitive Information
A website containing highly sensitive data, payment processing functionality and custom requirements should be hosted on a virtual private server or dedicated server to keep information isolated and safe, as hackers find it much easier to target websites on a shared hosting plan that all share an IP address.
5. You run an Online Store
Most eCommerce websites that store or process credit cards on their website need a PCI compliance certificate. According to a statistics, 89% of shared hosting plans fail to pass a PCI Compliance test. On a VPS, you have a dedicated operating system for your website, so you’re more likely to pass PCI test in comparison to shared hosting.
6. You need to Install Custom Software or Applications
Shared hosts don’t allow you to install your own software. Therefore, to host custom software like Game server, Forex Trading Software, Radio Station, Database Server, Streaming Server, File Server, etc., you’ll have to choose between a virtual private server and a dedicated server.
Some custom applications like Collections MAX, FreshBooks/QuickBooks, Billing Software, etc. demand 24×7 availability and high speed internet connection. To run these applications, you will need VPS hosting.
A dedicated server with moderate specification may cost you more than $100 per month, so VPS hosting is generally a sufficient and more pocket friendly
7. You Often see the “Service Unavailable” Error on your Website
The 503 ‘service unavailable’ error means that your server is temporarily unavailable to fulfill the web requests. It occurs when your site exceeds the allocated application pool memory in Windows hosting, or reaches to its maximum concurrent connections limit in Linux hosting.
Service Unavailable Error 503
How To Choose the Best VPS Hosting Provider
There are thousands of VPS hosting providers out there, so how do you know which is the best one? The following points will help you pick the right VPS hosting service.
Managed Service/Unmanaged Service
If you are familiar with hosting control panels, shell commands, and you have basic server administration and troubleshooting skills, then unmanaged VPS is the way to go. Note that while you purchase self managed VPS, you should be capable of managing applications, software, services installed on your VPS. Also, you must know installation/uninstallations, resource monitoring, server performance tweaking and troubleshooting of any technical issues.
If you think you are unable to manage such things on your own, or you don’t have such time to manage VPS, then choose managed VPS hosting.
If you are going to host websites with Windows based technologies such as ASP.Net and Microsoft SQL Server, you should choose the Windows VPS hosting. For PHP and MySQL based websites, a Linux based VPS is a perfect choice.
Your VPS host should have 24/7 support over live chat or phone along with a most comprehensive knowledgebase, so that when you face difficulties with your VPS in the odd hours, your web host’s technical team will help you to fix them.
Determine the VPS resources that you require to serve your websites, and then find the host who can offer you the best price. You should also make sure that your host offers a full money back guarantee so that you can assess the quality of support and VPS performance during the money back guarantee period.
Uptime And Reliability
Check how much uptime your web host offers. 99.5% and above is the recommended uptime score, but anything below 99% is unacceptable. You should also check the VPS provider’s past uptime records, and reviews on various forums, blogs, and third party trustworthy review websites.
The main Hypervisor where your VPS resides must be configured with brand new and highend hardware components. You can ask your web hosting provider’s sales executive about server configuration of main HyperVisor node.
Imagine that your VPS is infected with shell scripts and you don’t have a recent backup on your local computer. If your host takes regular backups of your VPS, then you can easily restore back your VPS to the previous state within a few minutes. If your host doesn’t take backups at all, you may end up losing hours of work.
AUP (Acceptable Use Policy) And T&C
You should take a look on the AUP or T&C as well before making the final decision. Some of the service providers follow the local state laws against the data protection and offensive/abusing activities.
So there you have it, our complete guide to VPS hosting. If you’ve had your site up and running for a while and it’s had some measure of success, you may have already experienced some of the issues mentioned. If you want your site’s performance to keep pace with its growth, you should consider upgrading to a VPS.
Many find that the benefits of having a virtual private server far outweigh the costs. How has your experience been with virtual private servers? Have you switched or thought of switching to a VPS or dedicated server? Let us know your thoughts in the comments section below.
