Virtual Private Servers (aka Virtual Machines or VMs) have been a great middle-of-the-road server option for hosting. You get the best of both worlds as far as performance and price is concerned.
The picture below is an excellent visual showing the differences between the Virtual Machine (Hypervisor) and Docker container models. The nice thing about Docker is it cuts the Guest OS component completely out of the equation. Meaning the fewer layers on the stack, the less resources are consumed.
However, that does not necessarily mean a docker will be the best choice for you. Both VMs/VPS and Dockers have their trade-offs. Whatever you’ll be using it for, then learning all the pros and cons will help you determine which works best for you.
