Microservices and orchestration

As we break down an application into very specific domains, we need a uniform way to communicate between all the various pieces and domains. Web services have served this purpose for years, but the added isolation and granular focus that containers bring have paved a way for microservices.

The definition for microservices can be a bit nebulous, but a definition from Martin Fowler, a respected author and speaker on software development, says this (you can refer to more details about this in point 2 in the References section at the end of the chapter):

As the pivot to containerization and as microservices evolve in an organization, they will soon need a strategy to maintain many containers and microservices. Some organizations will have hundreds or even thousands of containers running in the years ahead.
