AWS Lambda introduces public preview runtimes, a new way to try upcoming language versions before GA. Start using Node.js 26 and Python 3.15 today, provide feedback, and help shape runtime quality before general availability.

Feature toggles allow you to change application behavior in real time without deploying new code. Learn how to implement dynamic feature flags with AWS AppConfig on AWS Lambda for safe deployments, gradual rollouts, and instant rollback.

Learn observability best practices for AWS Lambda durable functions, including CloudWatch metrics, custom alarms, structured logging, and X-Ray tracing for debugging callback timeouts end-to-end.

Learn how to collect CPU and memory metrics from AWS Lambda MicroVMs using the CloudWatch Agent. Configure telegraf and OTel to monitor and right-size your workloads.

Learn how to prevent correlated hardware failures in distributed systems on Amazon EC2. This post walks through real incident response patterns, including Partition Placement Groups, composite alarms, automated recovery with Auto Scaling, and observability best practices.

AWS Outposts brings AWS infrastructure into your data center with low latency and data locality. But an Outposts rack has fixed compute. Learn how to build a Burst to Region pattern that overflows workloads to Amazon EC2 in the parent Region when local capacity is exhausted.

Customers building event-driven applications on AWS rely on Amazon Simple Queue Service (Amazon SQS) and AWS Lambda event source mappings (ESMs) to process millions of events every day. The fully managed polling infrastructure of ESMs eliminates the need to write and maintain custom code. You can focus on business logic while Lambda handles scaling, batching, […]

Stay current with the latest serverless innovations that can improve your applications. In case you missed our last ICYMI, read about what happened in Q1 2026. AWS Lambda MicroVMs AWS Lambda […]

If you manage Lambda functions at scale, you’ve likely hit the 75 GB code storage limit or explained to your security team why deployment artifacts live in an S3 bucket you don’t control. Today, we’re announcing self-managed Amazon S3 buckets for AWS Lambda deployment packages. Lambda reads your code directly from your bucket, eliminating quota […]

Today, we are releasing an expanded format of our Amazon CloudWatch dimensions for AWS Outposts capacity metrics. The existing CloudWatch metrics, AvailableInstanceType_Count, UsedInstanceType_Count, InstanceTypeCapacityAvailability, and InstanceTypeCapacityUtilization for Outposts, can now be grouped using the new AssetState dimension with values: Active, Isolated, or Retiring. In this post, we describe what’s changing and how you can use […]
