Architecting Continuous Integration and Continuous Deployment for Microservice Architecture

Regardless of the size of organizations, they are migrating to microservice architecture for multiple reasons. Many of them have found that by embracing microservice architecture they can deliver software faster and efficiently. Managing small, fine-grained, and autonomous services is easier and allows teams to work on them independently. Adaptation of Agile practices together with methodologies such as the twelve-factor app for building microservices, enable flexibility, efficiency, and increase the speed of delivering the software. However, implementing a repeatable, adaptable, and reliable process for releasing software can be very challenging. Continuous Integration, Delivery, and Deployment workflows are determined by organization cultures and preferences as well as technical requirements. This paper presents an approach on how to design and implement a CI/CD process following the best practices on the build, test, deploy, and release processes. It also describes the challenges of designing CI/CD systems, and it outlines potential answers to those challenges.
