Microservices architecture has become enormously popular because traditional monolithic architectures no longer meet the needs of scalability and rapid development cycle, and the success of some large companies in building and deploying services is a strong motivation for others to consider making the change.

However, performing the migration process is not trivial. Most systems acquire too many dependencies between their modules, and thus can’t be sensibly broken apart. It is for this reason that studies that provide information associated with the migration process to practitioners are necessary.

We have performed a rapid review to analyze the current state of the migration of monolith systems to microservices. In this investigation, led by Francisco Ponce, we discuss some key findings related to:

What techniques are used to migrate monolith systems to microservices?

What happens to databases during migration?
