When we start to learn a tool, we always try to use the tool on a standalone machine from which we gain expertise and can experiment various things. As and when we take the small setup to a big setup ranging multiple systems, there can be a lot of things that can hinder the performance or could not provide the optimum results that we get on a small setup. In order to achieve the best results, we require understanding and following some of the practices that have been followed by others leading to a higher performance and less troubles. In terms of programming languages, we have the concept of best coding practices, which describes how to write a code that is easy to understand, maintain, and read, which reduces the effort if someone else starts working on the same or similar piece of code.
