In programming we decompose big things into small, manageable chunks. In algorithms, we solve a small problem, and then use recursion or iteration to solve more complex problems. In software development, we create methods, and interfaces, and classes, and packages with the objective of being more efficient, and letting our code be more maintainable, manageable…so that a change in one part does not require a cascading change in other parts of the application.
Yet, we deploy as a monolith. All the packages run in the same JVM, in the same process. Classic example of this is the Java EE container, where all the wars, jars, and ears are deployed in the same JVM. In this page, I am jotting my notes on micro services, and a high level framework for designing micro services.
