Unmanaged VPS plans are available with a number of virtualization frameworks and hypervisors, with most users looking for "bare metal" isolation for increased security. Microsoft has also developed the Azure cloud platform for Windows servers on VPS hosting plans with elastic scalability that rivals AWS or Kubernetes. Windows is used frequently in private/public cloud orchestration for enterprise IT, whereas most small businesses running Windows servers for ASP.NET apps choose "bare metal" VPS plans.
Yes, it’s secure. VPS security comes from each instance’s isolation from the other environments on the server. Contrast that with shared hosting, where environments are sharing the same resources and can be affected by each other’s vulnerabilities. A denial of service attack on a website in a shared environment can bring down other companies’ data and websites hosted on that server, where each VPS environment is isolated and protected.
Keep firmly in your mind the sort of assets that you require to serve your site(s) when seeking a host. Cost in a VPS is important, but not as key as you might think. VPS resource availability is scalable, so the cost that needs to be looked at is comparable cost from one host to the next. Also – as cPanel revised their pricing model recently, web hosting companies across the board will have to pass those costs on to users sooner or later. You will need to consider the cost of control panel when selecting a VPS plan. Companies like ScalaHosting has developed their own control panel to mitigate this issue – so their users would have little issues with the price hike.
“After having shared hosting plans with other providers for many years, I switched all of my sites to Liquid Web a few months ago for my first VPS experience. It's been smooth, fast, and easy to use. At one point I suddenly ran out of disk space, and within minutes I was able to use their system to upgrade my plan and move my site to a larger partition.” – David K.
Every plan has some appealing configuration options. In particular, along with support for the usual Linux variants – CentOS, Ubuntu, Fedora, Debian – you can choose Windows Server 2008, 2012 or 2016 for only a $5 a month premium. That's very good value, and if you're more familiar with Windows than Linux, it could save you from lots of management hassles later on.
Each of these stack layers contain I/O routes for anonymous public network requests that must be penetration-tested by web security professionals. Users on managed plans can expect the hosting company to keep all of the web server stack software updated with security patches, while website owners under unmanaged plans will need to keep these aspects up-to-date personally.
Essentially, here’s the criteria I would use to judge things – if your site is made up of primarily static, HTML-based content, then you probably don’t need a VPS package. However, if you have a large amount of files stored, multiple sites, dynamic content, and the possibility of major traffic from time to time, then you might consider upgrading to a VPS. It’s a powerful package that allows you to do more than you could with a shared hosting plan, but requires less investment than a dedicated server.
