Affording a good server is only part of the issue when you want or need a quality server online. A dedicated server for my little but growing website would be great, but there was no way I could afford the major expense. Shared servers can be hit or miss in quality. You need to be careful. However, in looking for the best VPS, I found something that was not only affordable but perfectly useful for me too.
A VPS is a Virtual Private Server. If you have a website online or do anything else on the Internet where other people need to access your files, programs or any other data, you need to make that data available to them quickly. You could buy a computer and hook it up to your own Internet service to act as a server, but Internet service providers thwart that by limiting upload bandwidth. Sure, you can download mega files and stream movies into your devices, but uploading is slowed. Your Internet would be crippled even if only a few people were trying to access your data at the same time.
This is why having the best VPS online is helpful. A VPS is a bunch of individual operating environments active on a single computer. Instead of needing a separate computer for each incidence of an operating system and its installed programs, there can be a bunch of them running at the same time. The processors and RAM are so sufficient that the speed of access the public experiences seems like they are getting stuff from a dedicated piece of hardware connected to the Internet backbone.
You know how you can log onto your computer and then switch to another user with your stuff still ready to go when you switch back over? Well, a VPS is kind of, but not exactly, like that except that both users could be active at the same time. A VPS can have a lot more than two separate instances of an operating system running on a single computer at one time. Each user has full access to tweak the OS to make a website run. They can install and uninstall programs. No other user has access to your files. Being that one computer is used for so many, it saves money. Unless you got a major website that needs a dedicated server, this is a way to save a lot of money.
