In fact, before we even had the word microservices in our lexicon, back when it was just good old-fashioned service-oriented architecture, we were talking about data: how to access it, where it lives, who “owns” it. As I expanded upon in my book, Building Microservices , a shared database creates a huge coupling point in your architecture.

One distinct trend is a belief that a JavaScript framework and Single-Page Architecture (SPA) is a must for PWA development. It simulates a link with a 400ms RTT and 400-600Kbps of throughput (plus latency variability and simulated packet loss). Our baseline, then, should probably trade lower throughput/higher-latency for packet loss.
