The life of a developer is full of creation, solution finding, and many lines of code. But there's an ongoing fight, too: keeping a development environment secure yet flexible. It should carry different tools, libraries, and frameworks while staying reliable and performing well. In the past, developers used to depend on physical machines that were set up for their projects.
This method has many limitations. Initially, it might be costly to sustain a separate machine for every project, especially if the applications use many resources. Next, physical machines restrict programmers to working from one place only.
Last but not least, maintaining software compatibility and settings consistent on several machines could require extra time and may also not be error-free.
This is where virtual machines (VMs) have changed the game. VMs are software applications that create a virtualized environment that behaves like a computer. This environment can be set up to run particular operating systems and applications. It permits developers to make isolated and tailor-made development surroundings.
