Virtualization on the OS Level provides the best performance and scalability compared to other approaches. Performance of such systems can differ only about 1-3% from standalone server. They are also much simpler to administer as all of the Virtual servers can be accessed and administered from the host. Generally, such systems are best choice for server consolidation of same OS workloads.
Other powerful features included in InterServer VPS hosting plans are high performance SSD storage, easy to use VPS control panel, instant provisioning, and 99.9% uptime guarantee. They also provide 100s of free scripts to make it easy to install the most popular applications on your VPS server.

Buying a VPS plan means that you get your very own virtual server environment. You have full control over the operating system, the extensions and apps you install, and all their settings. Each physical server will still host multiple VPS customers, but not as many as with shared hosting, and typically each VPS will be allocated a share of key resources – RAM, storage space, CPU cores – for their use alone.
Be careful, though – there are some common traps many people fall into. Firstly, the promotional prices are only on offer for a month, after which you’re paying between $49.99 and $299.99/month on any of its five plans. Secondly, the 30 day, money-back guarantee is only valid for those who subscribe for a year or longer. Everyone else only has 48 hours to claim a refund.
