To make your site accessible online, you need to host it on a web server. You can have a webserver in-house or buy a hosting service as per the needs of your site. There are various web hosting plans to choose from, including Shared Hosting, VPS Hosting, Cloud Hosting, Dedicated Server Hosting, etc. Today, we are going to talk about VPS Server Hosting services.
While opting a Virtual Private Server Hosting plan, you can choose from Windows or Linux VPS Hosting plans. A hosting VPS offers a range of features and benefits, including dedicated resources, account isolation, and complete root access. In this article, we will be talking about a specific feature of a virtual server – account isolation in detail.
A host creates a virtual server by using server virtualization techniques. This allows the host to create multiple virtual servers on a single web server and offer dedicated resources and complete root access with each of them. Further, the virtualization software ensures that each virtual server is isolated from the others. Before you decide to buy VPS Hosting, go through this article to understand how Account Isolation works in VPS.
VPS Hosting and Account Isolation
As mentioned above, the host uses virtualization software to create virtual servers. The virtualization software is powered by the hypervisor, which is responsible for creating a partition in the hardware and allocating resources like RAM, CPU, etc.
An important role of the hypervisor is ensuring that no two virtual servers use the same hardware. This forms the basis of account isolation on a VPS Server. Since the hardware is not shared, anything happening to one virtual server cannot impact the others.
The following video offers a visual guide to the meaning and working of hypervisors:
Account isolation is an important feature of VPS Hosting since it allows users to use a Dedicated Server-like hosting environment at a lower cost. When you couple account isolation with complete root access, you have the platform to create a hosting environment as required by your site. Hence, account isolation offers more customization options and boosts the server’s security.
IP address allocation
In a VPS Hosting plan, the host also ensures that each virtual server has a unique IP address. This helps ensure that the virtual server works in complete isolation from the others. If you look at a Shared Hosting service, one IP address is shared between all users on the server. Therefore, if the IP address gets blocked due to one user’s fault, all others are affected. In VPS Hosting, with a dedicated IP, this is not a concern.
VPS Hosting services gained popularity for being a cost-efficient option compared to Dedicated Servers. Hence, account isolation is an important feature as it allows the site owner to use a Dedicated Hosting environment. If you are looking for an affordable VPS Hosting plan, then before you begin your search, ensure that you assess your site’s requirements and choose the best. If you are already on a Shared Hosting service and looking for an upgrade, then a VPS can be a perfect median between Shared Hosting and Dedicated Server Hosting plans.
