When you are the only developer in the team or you are developing solo, you usually only care about the differences between your machine and the server.

A lot of techniques or approaches have been used to try to solve this issue and one of them is virtual machines (VM). A virtual machine is a simulation of a real machine using virtual components that mimics the computer architecture and allows you to run an operating system inside it. This also removes the issue of different operating systems across developers, such as Linux, Mac OS, or Windows.
This approach allows us to have the exact same...
