Serverless Observability with Thundra
● Tricky: Understanding the async structure of serverless environments.
● Hard: Reduce the MTTR in serverless environments.
● Impossible: To use the already existing APM for Lambda because they’re
not lightweight.
Thundra aims to resolve the issues below by
providing light-weight libraries in Java, Node.js,
Python, .NET, and Go. With Thundra, you can
both have an overall idea in the most complex
architecture and have the power of debugging the
code even line-by-line. Plug it with Lambda
Layers and using well-known deployment tools.
