However, the automatically-generated certificate is "self-signed" which means users will get browser warning that the connection can't be trusted (because there might be a man-in-the-middle intercepting the encrypted traffic). The solution is to install a free LetsEncrypt certificate by going to Virtualmin > Server Configuration > SSL Certificate > Let's Encrypt > Request Certificate. If you've done everything correctly your web site will now load with no warnings.
Some systems administrators will also install Nginx (or Lightspeed / Lighttpd on BSD) as alternative server frameworks to Apache using VPS plans. For example, Nginx, Varnish Cache, & WordPress can be installed on VPS hosting plans to support up to 2x the simultaneous user traffic and pageload speeds for high traffic websites when compared to the most common Apache servers. Hadoop, Tomcat, VPN, & email servers can also be run on VPS plans. Cloud VPS platforms support web and mobile applications at scale by replicating under elastic cloud architecture and can speed up DevOps deployments using snapshots like Bitnami.

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.
You’re paying more, so there SHOULD be a minimum uptime guarantee and better server speed. Look for a host that offers 99.5% at a very minimum, although ideally, I’d rather go with someone who offers 99.9%. Search through some reviews as there are many who have put this to the test. For example, any of WHSR’s many web host reviews include an uptime record as one of our key tests.
