In software development, there are times you want to develop solutions with several moving parts and your team consists of software engineers who are proficient in the use of different programming languages. It might present a challenge in some cases as you typically need all your engineers to use the same programming language in building a software solution.

Microservices is a very popular software architectural style that lets different software engineers bring their different programming languages to the table and collaborate despite the language difference. How it is done is that the project is broken down into smaller bits and assigned to the team members who build their part of the solution using their most preferred language.

Ultimately, you have a more agile team who are able to adapt and you have a software solution that is in line with where the industry is moving to in order to properly integrate with cloud computing. Simply put, microservices are like jigsaw puzzles, as long as it fits, you can make it work. The job of deciding on software architectural patterns, designs, or styles is made by the people with senior developer experience and above as such junior developers need not concern themselves with having to make those decisions. I do believe that it is important to learn about these decisions and the thought process of why they make use of microservices on some projects and monolithic on other projects.
