Understanding Account Isolation in VPS Hosting

VPS Hosting
It is no secret that a website functions better with dedicated resources as compared to shared resources. However, getting dedicated computing resources can be costly. While shared hosting offers a great hosting option to websites with lesser traffic, it falls a little short for websites who need better performance of the web server and/or dedicated resources. In today’s article, we will talk about Virtual Private Server Hosting or VPS Hosting services and understand how account isolation works in these plans.

Account Isolation in VPS Hosting 


As the name suggests, in VPS Hosting, the provider hosts your website on a private virtual server. In order to create the virtual server, he uses virtualization and divides the physical web server into multiple parts – each having dedicated resources. The software used for this is called Hypervisor. Each virtual server has its own Operating System, CPU, and RAM. While one physical web server might have several virtual servers on it, each one of them works in isolation from the others. Further, the provider can simply add another section in case the website needs more resources.

It is important to understand here that since the resources are not shared, the performance of the other websites on your web server does not affect the performance of your site.

IP Allocation 


Let’s say that you are using a traditional shared hosting plan where the web server is shared without creating virtual servers. Now, let’s assume that one of the websites residing on your server decides to spam people with 10 emails a day in a desperate attempt to increase business. Unfortunately, this backfires and several users report the emails as ‘Spam’. This eventually results in the IP getting blacklisted. Now, since all resources are shared, the IP is shared too. Therefore, all other websites will now be unable to send emails to those domains too!

In VPS Hosting, each virtual server has a different IP address. Hence, this concern is completely eliminated.

While account isolation in VPS Hosting is beneficial, we would like to specify here that we are not saying that VPS Hosting is the best hosting solution for all websites. If costs are a concern and the nature of your website does not mandatorily require a 24x7 presence, you can afford to have average page load speeds, then the traditional shared hosting plans make perfect sense for you.

Summing Up 


Remember, account isolation allows the hosting providers to offer assured resources to websites without having to bear the costs of a dedicated server. Even though the web server is being shared, account isolation ensures that websites feel like they are using a dedicated server at marginal costs.
