Step Functions workflows can now be exposed to agents as tools through AgentCore Gateway. What the connector offers, how to write a workflow that is safe to hand to a model, where the IAM boundary sits, and eighteen scenarios tested on Step Functions Local.

Breaking the 29-Second Wall: Serverless GenAI & Agent Backends on AWS
The API Gateway 29-second timeout is now a default, not a wall: REST APIs can stream for 15 minutes, and Lambda durable functions and Bedrock AgentCore handle work that runs for hours. This article sets out the current limits, three production patterns for long-running GenAI requests with tested code, and the concurrency and cost consequences of each.

Enterprise GenAI integrations are fatally exposed when treating foundation models like standard REST APIs. Integrating Claude 3.5 Sonnet directly to heavy UI components results in chronic HTTP timeouts. By early 2026, the industry standard relies on DynamoDB streams, EventBridge, and AWS Step Functions. Here is the practitioner blueprint for robust, asynchronous LLM orchestration at scale.
Read more →Amazon Bedrock Flows vs Step Functions: When Visual AI Orchestration is the Right Answer
When Amazon Bedrock Flows debuted, it looked conspicuously like AWS Step Functions rebuilt for GenAI. 15 months later, the architectural divide is strictly enforced. Bedrock Flows handles ephemeral, cognitive prompt chains; Step Functions handles durable business transactions. This is the blueprint for the Hybrid Orchestration Pattern separating AI intent from Systemic persistence.
