There’s a new kid on the block in the world of workflow orchestration, the Lambda Durable Function, which allows an orchestration to be created as a single Lambda Function which can run for up to a year.

- How do you build an orchestration?
- How much will it cost?
- What pitfalls should you look out for?
- Can it do everything you need?
- How do you test or debug it?

Are just some of the questions developers will have about this new extensions to Lambda.

This talk will take an existing production workflow and look at how it could be built as a Lambda Durable Function from start to finish. I’ll implement the complete workflow, look at how the checkpoint/replay execution model affects this implementation, test and debug the workflow, and look at the built-in observability all through a number of demos and hope to have answered those questions.
