Essential open source tools for serverless developers
4 likes711 views
This document discusses essential open-source tools for serverless developers, highlighting the importance of using established deployment frameworks over creating custom ones. It emphasizes qualities to consider in infrastructure as code (IaC), such as syntactic correctness and interoperability, while also warning against common pitfalls like automating without understanding. Additionally, it lists various tools and practices to enhance serverless application development and management.

- 24. Picking a deployment framework because it lets you write Javascript is like picking a car because it has red seats. Your priorities are WRONG!
