On a high level, Temporal consists of two distinct components Temporal Server and Temporal Client components (running as part of your applications deployment). Once my end to end basic flow was finished, I decided to work on making my Orchestration service more resilient by validating input, handling failures from downstream services in a graceful way, etc. The microservice defines an approach to the architecture that divides an application into a pool of loosely coupled services that implements business requirements. Another plus is that this way you can reuse code between the services. A Java-based, open-source framework to create web applications, Spring Boot has been dominating the web development landscape ever since the official release of Spring Boot 1.0.0 in April 2014.
