VPS Servers basically "virtual machines" run on much larger servers (typically on virtual multiples).
Although they worked very well, they were somewhat under-utilized until the launch of the Amazon "EC2" service in early 2010. This has allowed people to install a VPS on the infrastructure repository … not just on a server – minimizing the underlying costs.
Today, another "cloud" VPS service provider (including DigitalOcean, Vultr and others) followed Amazon's leading role in ultra-low "VPS" servers in cloud cloud infrastructure. Our customers started from $ 5 / mo (or Vultr $ 2.50 / mo).
The bottom line is that with the new price drop, "cloud" VPS providers effectively provide companies and end-users with expandable software hosting services with "shared" hosting prices. The most important thing is that we are able to control (and ours) the underlying infrastructure, while we did not know it before.
Although this is great, there is a big problem – you are responsible for setting up and upgrading your servers, and so on. Stb. Even if you access the path of a "supervised" server infrastructure using management management (for example, CPanel) that allows you to manage various services running on your system.
Finally, in order for VPS (or any server) to work properly, you need to have the various software needed to make the webserver work effectively; which includes the "web server" software, the underlying libraries / dependencies at the operating system level, and the programming language of the server you want to use.
In addition, you need to make sure that the server has to handle the applications required to manage the programming languages with the most appropriate application server software to run the applications that you want to install on your system.
Most people do not know / notice – if you are running Ruby on Rails / NodeJS on your server, you must ensure that you have the right server software to support your requests. In the absence of this (and this is why most "shared hosting" is inappropriate), then relatively little will be done to manage the subordinate system.
To solve this, the most effective is the "management" system of VPS platforms. If you have a system that has allowed you to manage the software running on the infrastructure, it will give you the ability to accurately determine what you need.
