Lots of people tell you how to do things properly. Here are some things I’ve inherited in our Ansible that break things in horrible ways.
Coupling is (roughly) how interconnected different components of a system are. One of the most common patterns in modern software engineering is loose coupling.
The idea of separating things across an API so that you can change things behind the API without having to change other components is very powerful.
The lean model for continuous improvement looks something like this:
Where you start is a matter of some debate, as is the direction of flow. However, most people start with the idea of building a Minimum Viable Product (MVP) as an experiment; measuring the results; and then learning from the measures they recorded, which then feeds into the next build of the product.
What is an MVP for a Database Reliability Engineer (DBRE)? A good, old-fashioned manual install. A best practices manual install.
