The document discusses cloud-native debugging solutions for production environments, emphasizing continuous observability and the limitations of traditional debuggers. It introduces Lightrun's IDE plugin that allows developers to insert actions at runtime with minimal overhead and mentions security and privacy considerations. The method is designed to operate across various environments, ensuring a stable and efficient debugging process.

be a Better Way!

21. We don’t know what
we’ll run into

Could Debug…

the Right Tool

24. They Can’t Cross
Server Boundaries

Continuous Observability is a
streamlined process of constantly
asking new questions and getting
immediate answers.
