Microservices
Creating a Microservice? Answer these 10 Questions First
Microservices appear simple to build on the surface, but there’s more to creating them than just launching some code running in containers and making HTTP requests between them. Here are 10 important questions that you should answer about any new microservice before development begins on it – and certainly before it gets deployed into production. 1. How will it be tested? Microservices have an interesting set of benefits and drawbacks when it comes to testing. On one hand, unit testing a small service that represents a well-defined piece of functionality is likely a lot easier than testing an entire monolithic application. On the other hand, verifying the quality of a whole application that is composed of many microservices can represent a significant amount of testing complexity: instead of running a single command to test the code running in one process, a large number of integrated dependent components must be running first, verified as healthy, and stay running throughout the tests.
