Creating a microservice requires careful consideration of several key factors before development begins. This includes how it will be tested, configured, and consumed by other parts of the system, as well as its security, scalability, and reliability. Understanding how dependencies will fail and how the rest of the system will handle their failure is also crucial. Additionally, having a plan for upgrading and monitoring the microservice is essential to ensure its continued improvement and reliability. By considering these 10 important questions, developers can create a mature, resilient, and reliable microservice component that meets the needs of their application and minimizes operational complexity.
