This is part two in a three part series looking at local microservices running in the same process.  Part one identified the coupling problems in Object Orientation behaviour (found here).  This article will look at how microservices are helping reduce the coupling problem. Part Two: Breaking up the Jigsaw Part one identified that object behaviour coupling is similar to a ...

This is the first in a three part series on how I see microservices are helping in relieving the Object Orientation behaviour coupling problems.  In looking at this problem, it identifies the ability for “local” microservices. The three part series will look at the following: Identifying the Object Orientation behaviour coupling problemHow microservices are reducing this coupling problemHow local microservices ...
