Cockcroft’s analogy is that you want to think of servers like cattle, not pets. Instead you should think of your servers like a herd of cows. That can make it more difficult to clean up your codebase by decommissioning old file versions (because you have to verify more carefully that a revision is no longer being used), but that’s an acceptable trade‑off for how easy it is to add new files as you build new microservices. They all perform the same functions, so you don’t need to be concerned about them individually. Home› For example, it might examine every database that stores subscriber IDs, to verify that the same IDs exist in all of them (there aren’t missing or extra IDs in any one database). You want the team for each microservice to choose the database that best suits the service. Breaking apart the data can make data management more complicated, because the separate storage systems can more easily get out sync or become inconsistent, and foreign keys can change unexpectedly.
