This week Tim Bray joins Simon to discuss a new capability in AWS Step Functions. Express Workflows are a new type of AWS Step Functions workflow type that cost-effectively orchestrate AWS compute, database, and messaging services at event rates greater than 100,000 events per second. Express Workflows automatically start in response to events such as HTTP requests via Amazon API Gateway, AWS Lambda requests, AWS IoT Rules Engine actions, and over 100 other AWS and SaaS event sources from Amazon EventBridge. Express Workflows is suitable for high-volume event processing workloads such as IoT data ingestion, streaming data processing and transformation, and high-volume microservices orchestration.
