From Functions to Interfaces — the Product Evolution of Serverless RESOURCES https://x.com/shamasis https://github.com/shamasis https://www.linkedin.com/in/in/shamasis https://shamasis.net ABSTRACT Serverless promised freedom from infrastructure. What we got was faster delivery and smaller units of compute - but also fragmented interfaces, endless YAML, and an army of devs reinventing CRUD endpoints one Lambda at a time. Today, the true interface of any serverless system is not the function - it’s the API. And that API isn’t just a contract - it’s the system’s surface. This talk explores a shift: to build and scale serverless systems, we must stop thinking function-first and start thinking API-first. From design to testing to mocking to versioning, the API is the new infrastructure. And as AI enters the picture - with autonomous agents calling, composing, and even writing functions - the story shifts again. The future is beyond function-oriented; it’s API-native, AI-forward.
