AWS announced that Lambda durable functions are now available in the AWS GovCloud (US‑West) and GovCloud (US‑East) regions. The feature lets developers add "step" and "wait" primitives to Lambda code, so workflows can pause, checkpoint, and recover from failures without paying for idle compute. It works with Python 3.13/3.14, Node.js 22/24, Go 1.24+, .Net 2.2 and Java 17+. Customers can enable it via the console, API or infrastructure‑as‑code tools like CloudFormation.
