SPIKE - Lambda power tools and SAM

[PriyaBasker23]

User Story

As an engineer on the data platform I want to reuse existing solutions for common problems in API development where suitable So that I have more time to spend on problems unique to the data platform

Value / Purpose

Lambda power tools and AWS SAM (Serverless Application Model) are both tools designed to make it easier to build APIs - that adhere to the Well Architected framework - using lambda and API gateway. They can be used together or independently.

We want to evaluate these tools and see whether they would help with problems we are facing, such as

• deploying our API code separately from the infrastructure in the modernisation-platform-environments repo
• validating/parsing request data
• testing the API locally
• making requests idempotent
• simplifying the implementation of the API
• simplify API metrics, tracing, logging implementation

Proposal

Create a proof of concept version of the API that uses these tools, so we can evaluate whether it will help us.

Additional Information

• https://blog.walmsles.io/making-all-your-apis-idempotent
• Powertools docs
  • Powertools tutorial (a good walkthrough)
  • Another example lambda with Powertools

  • AWS SAM and Terraform

Definition of Done

• [ ] Have a proof of concept/recommendations to share with the team
