AWS Lambda now exposes Availability Zone metadata through an endpoint in the execution environment, so your function can discover its AZ ID with an HTTP request. Use it to prefer same-AZ endpoints for services like ElastiCache, Amazon RDS, and MemoryDB, reduce cross-AZ latency and data transfer costs, and build AZ-aware resilience patterns.

AWS Lambda SnapStart now supports container image functions, reducing startup times from several seconds to as low as sub-second. Learn how SnapStart for container images works, how to enable it on new or existing functions, and best practices for latency-sensitive workloads.

EC2 Tag Sharing lets AMI owners share tags with any account that has access to the image, using the ec2:SharedTag/ prefix. Updates propagate automatically with no custom replication workflows. This post walks through how it works, a golden AMI use case, and considerations for ABAC policies and account governance.

Amazon EventBridge relaunched the Custom event bus so a platform team can share one governed bus across the organization while application teams publish and subscribe from their own accounts. See how retention, ordering, open formats, transformation, and direct target delivery change what one bus can carry.

AWS Lambda now supports scalable network bandwidth for functions with 2,048 MB of memory or more running outside a VPC. Sustained throughput scales from 625 Mbps up to 3,000 Mbps at 10,240 MB, reducing execution times and per-invocation costs for latency-sensitive data processing workloads.

Learn how to run AI agent tool calls in secure, isolated sandboxes using AWS Lambda MicroVMs. This post shows how to architect a self-hosted control plane that launches a fresh, VM-isolated MicroVM for each agent session, keeping credentials, networking, and governance entirely within your own AWS account.

Amazon API Gateway execution logs help you trace request processing step by step through your REST API stages. They capture authorization results, integration latency, mapping template output, and error details that are otherwise invisible at the API surface. When a production request fails in a way the access log cannot explain, the execution log is […]

AWS Lambda now supports a 90-minute function timeout for asynchronous and event source mapping (ESM) invocations on Lambda Managed Instances, a 6x increase from the previous 15-minute limit. Data processing, media transcoding, AI inference, and batch workloads can now run on Lambda without re-architecting.

Enterprises that use Amazon API Gateway often want to bring their own client certificate for backend mutual TLS (mTLS) authentication. With API Gateway, you can now use a third-party or AWS Private CA-issued client certificate for the outbound mTLS handshake. In this post, you build a REST API with an outbound mTLS connection to an Amazon ECS backend.

The Amazon Linux kernel-default SSM parameter now updates to point to the latest kernel version as new releases become available. This post explains what this means for your workloads and how to manage the transition.
