Step Functions Evolution: JSONata and Simplified I/O Transform Workflow Development

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 For more details check ⁠here⁠.
