Description

Architecture Corner Newsletter Podcast explores the latest developments in cloud-native architectures and serverless computing patterns that are reshaping how we build distributed systems.

In this episode we will cover:

  • AWS Step Functions' new JSONata support and how it shifts functionality from Lambda functions to the state machine itself
  • The introduction of variables and simplified Input/Output processing that reduces complexity for developers
  • Real-world examples of replacing custom Lambda code with JSONata expressions for filtering, calculations, and data transformations
  • Trade-offs between low-code approaches and traditional development practices, including testing considerations
  • Strategic guidance on when to leverage these new capabilities versus maintaining custom code solutions
