This document summarizes Muhammad Edwin's presentation on API lifecycle management with open source products. The presentation covers what an API is and its importance in microservices architecture. It then defines the stages of an API lifecycle as design, mock, publish, manage, and operate. It provides examples of open source tools that can be used at each stage, such as OpenAPI, Microcks, Castle Mock, Ansible, and Jenkins. The presentation emphasizes that managing the entire lifecycle of APIs is important as the number of services, developers, and operations scale.

a very simple life
What is an API

8. What is an API
But it have a downside,
not scalable enough, need to either scale up or scale out
16gb to 32gb
1 instance to 3 instance

19. API Design Principle
What is API Lifecycle
1. Contract First Approach
• Open API Specification
2. Ensure Testability of APIs
• Mocks
• Unit Testing
• Integration Testing
3. Semantic Versioning
• Minor versions are backward compatible and updated “in place”
• Major versions are deployed “side by side” with older versions
4. Idempotency
5. API Management As Code
