The content discusses the adoption of event-driven architecture (EDA) by KnowBe4, a security awareness training provider, to address the challenges of legacy systems and create a scalable and flexible software engineering environment. The post highlights the journey of implementing EDA on Amazon Web Services using Amazon EventBridge, enabling decoupled communication between applications. Through the use of event replay capabilities, idempotency, and schema validation, KnowBe4 was able to overcome challenges and improve development velocity, resiliency, and scalability.
The post emphasizes the importance of defining standard event schemas for consistency and clarity, as well as detailing event payloads and metadata structures. It also covers the implementation of infrastructure as code (IaC) to simplify the creation of publishers and subscribers, and the use of bus topologies to support multiple development teams across different AWS accounts.
The content further explores the custom event publishing API created by KnowBe4, which is responsible for validating event schemas, calculating payload sizes, and posting events to the event bus. Performance metrics during load testing are also discussed, demonstrating the system’s ability to handle a high volume of requests with minimal errors.
The post concludes with insights on the success of KnowBe4’s adoption of EDA, including increased development velocity, fault tolerance, and scalability. Part 2 of the series will delve into the implementation of an audit log subscriber within their event-driven architecture.
Overall, the content showcases how KnowBe4 leveraged EDA to drive innovation, improve efficiency, and foster a culture of continuous improvement within their organization. The strategic decisions made in implementing EDA highlight the benefits of decoupled communication, scalability, and resilience in modern software engineering practices.
