Temporal Serverless Workers for AWS Lambda is now in Public Preview for Temporal Cloud users. It lets you run Temporal Workers on AWS Lambda without managing infrastructure, autoscaling policies, or long-running processes. When tasks arrive on a Task Queue, Temporal invokes Lambda functions directly in your AWS account, scales from zero automatically, and shuts down when work is done. Supported SDKs include Go, Python, Java, .NET, and TypeScript. Setup requires uploading Worker code to Lambda, creating a cross-account IAM role via a CloudFormation template, and registering the Lambda ARN with Temporal via CLI or UI. Best suited for bursty, event-driven, or low-volume workloads; self-managed Workers remain preferable for sustained high-throughput scenarios.
