📣 AWS Lambda now offers durable functions in 14 additional Regions, enabling developers to build reliable multi-step applications and AI workflows closer to users and data. Durable functions add primitives such as "steps" and "waits" to checkpoint progress, recover from failures, and pause execution without incurring compute charges for on-demand functions. Activation is available for new Python (3.13, 3.14) and Node.js (22, 24) functions via the API, Console, SDK, or Infrastructure as Code tools like CloudFormation, SAM, and CDK.

🔁 AWS announced Lambda durable functions, a built-in capability for authoring reliable multi-step applications and AI workflows within the Lambda developer experience. Durable functions automatically checkpoint execution, can suspend runs for up to one year, and recover from failures without requiring additional infrastructure. New primitives like steps and waits let developers pause and resume logic without incurring compute charges, while the service handles state and error recovery so teams can focus on business logic.

⚙️ AWS Lambda Managed Instances lets you run Lambda functions on Amazon EC2 instances while preserving Lambda's serverless operational model. AWS fully manages instance lifecycle tasks — including OS and runtime patching, routing, load balancing, and autoscaling — and exposes the broad EC2 instance catalog (including Graviton4 and high‑bandwidth networking). You attach functions to a configurable capacity provider via Console, APIs or IaC, and the service integrates with CloudWatch, X‑Ray and AWS Config; current Java, Node.js, Python and .NET runtimes are supported. The feature is now available in US East (N. Virginia, Ohio), US West (Oregon), Asia Pacific (Tokyo) and Europe (Ireland).

🆕 AWS Lambda now supports creating serverless applications with Node.js 24, available as both a managed runtime and a container base image. AWS will automatically apply updates to the managed runtime and base image as they become available, and the runtime is offered in all Regions including GovCloud (US) and China.
