Most VPS hosts only offer servers running Linux-based operating systems; you'll need to dig a bit to find Windows-based VPS hosting. This is important to note if you're planning on running software that requires a Microsoft-compatible environment. That said, Linux-based VPS hosting will save you a few bucks; Linux servers usually cost $10 to $20 less than Windows servers.
VPS ensures that your website continues to run smoothly, regardless of what is happening elsewhere on the server. It also protects your data from multiple sites, giving you a secure piece of virtual real estate to build a website on.
One of the most popular recent innovations in cloud hosting plans is the use of operating system snapshots to install full server stack software including popular CMS code and web development frameworks. For example, instead of buying a bare-metal VPS plan and installing all aspects of the OS, Apache software, programming language extensions for the web server, database frameworks, etc. individually or via the command line, system administrators can simply choose a particular stack snapshot and deploy LAMP with the latest Drupal, Redis, Varnish, Zend, Acquia Cloud, & Apache Solr versions all pre-configured under PHP 7 settings. Entire production server portraits can be captured using this method and used for backup/restore, clone site replication, elastic scaling, load balancing with multiple website copies, etc. Snapshots work with Docker containers and Kubernetes as well as VPS plans under KVM, Xen, Virtuozzo, SolusVM, OpenVZ, VMware, etc. virtualization.
