Any business operation can be performed well when a set of resources are dedicated to it. Managing a website is no different. But whenever there is a clause of exclusivity, it essentially involves cost. Even web hosting. While dedicated hosting can give you complete independence and control over your site management, it comes for a hefty price. But, the budget can be a major constraint for most businesses, especially at the start. That is why many sites find themselves on a shared hosting platform, although they end up compromising on the site performance and resource availability. There is, however, an effective solution that sits right in the middle of shared hosting and dedicated hosting.
And it is VPS Hosting. As the name suggests, VPS or Virtual Private Server Hosting uses multiple virtual servers which are isolated from each other, making them mutually exclusive.
How are the accounts isolated?
In VPS hosting, the site is hosted on a private virtual server. The central server is then multiplied into smaller servers through virtualization and thus, the physical space is broken down into part. Each such smaller server is provided with its own resources, which are independent of the other servers in the system. The software used to do this isolation is called Hypervisor. It enables each and every virtual server with its own operating system, applications, tools, hardware resources like CPU, RAM, storage, etc. Although all the virtual servers eventually share the main physical server, they all work in isolation from each other. This does two things. One, it gives the site admin/owner ample control on the site and independence to configure the system as they want and add new resources in case any need arises. And two, it keeps each server unaffected by the other. So, whether one server is working or not working, or has undergone a failure, the other servers continue to work in their own space and pace and remain unaffected.
Individual IP Allocation
Another way the virtual servers are isolated is through the IP address. Because every server is separate, it only makes sense to have their individual IP allocated to them. This saves the site probable trouble that might be arising out of the server’s IP. For instance, on a shared hosting platform, all sites use the same IP, since they are on the same server. If one of the sites on the central server is spamming its users, the chances are that when the user spams the mail server, it can block the entire IP address. Thus all the other sites using that IP will face the brunt of the situation. But in VPS hosting, with every server having their unique IP address, chances of such mishaps are next to zero.
Account isolation allows site owners to enjoy the privileges of dedicated hosting but without bearing the hefty costs of the same. Thus making VPS enjoy the best features of shared and dedicated hosting. But before you choose your hosting provider, always research thoroughly, ask questions, and ensure all your hosting needs are duly met. Good Luck!
