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. All too often, the software wasn’t designed in a way that made it easy to ship. And data was at the heart of the problem.

This can dramatically decrease network latency and its effect on the end-user experience. Because cloud architectures are more distributed and dynamic resources come and go as needed, performance can be varied. By establishing these, you can work backward to ensure every step of the process is designed to serve these outcomes.
