Building Scalable CI/CD Pipelines with Self-Hosted GitHub Actions on AWS CodeBuild
Discover how PostNL is transitioning to a serverless CI/CD solution by hosting GitHub Actions on AWS CodeBuild. This session dives into the architecture and practices that centralized workflows in a single AWS account while maintaining scalability and security. Attendees will gain practical insights into setup, cost optimization, and best practices for managing workflows in a large AWS organization environment.
Refactoring a Lambda Monolith to Microservices Using Hexagonal Architecture
In many applications, a single Lambda function contains all the application logic that handles all external events. The Lambda function sometimes acts as an orchestrator, handling different business workflows within complex logic. This approach has several drawbacks, like big package size, difficulty enforcing least privilege principles, and hard to test. In this session, I will explain how to leverage the Hexagonal Architecture, also known as the “Ports and Adapters” approach, to refactor a Lambda monolith into microservices.
