Excerpt
Microservices certainly aren’t a panacea, but they’re a good solution if you have the right problem. And each solution also comes with its own set of problems. Most of the attention when approaching the microservice solution is focused on the architecture around the code artifacts, but no application lives without its data. And when distributing data between different microservices, we have the challenge of integrating them.
This book explores some of the reasons you might want to consider microservices for your application. If you understand why you need them, we’ll be able to help you figure out how to distribute and integrate your persistent data in relational databases.
