The microservices architecture is far from a new trend; it's generally accepted as a better way to build apps these days. The common way to build apps was, until a few years ago, the monolithic approach—which was, if you look at it from a functional perspective, basically one deployment unit that does everything.

It's much harder to make changes, as the code base becomes bigger and more people make changes to it. read more

This is actually at the heart of what the software is, a community-driven software package with full transparency into the code base. Governments care about open source because it provides three powerful benefits: monetary savings, improved quality, and better security and privacy. This last benefit is often less-than-obvious, but equally important. read more
