In his talk, Leo Hanisch discusses transitioning from a Lambda-Lith to an event-driven architecture, as experienced by Siemens over three years. The term 'Lambda-Lith' arises from the reliance on AWS Lambda for serverless computing while creating monolithic systems due to tightly coupled code. Hanisch illustrates this challenge through an example architecture involving API Gateway, Lambda, and DynamoDB, initially appealing but rapidly becoming complex and cumbersome. He highlights the need for better practices to evolve from this state toward a more sustainable and scalable event-driven architecture framework.
A Lambda-Lith refers to a serverless architecture that inadvertently turns into a monolith due to tightly coupled code within AWS Lambda functions.
The journey of transitioning from a Lambda-Lith to a more event-driven architecture has greatly improved our system's scalability and maintainability at Siemens.
