Amazon EC2 Capacity Manager offers real-time supportability checks and capacity fulfillment metrics for large EC2 fleets. This post shows how to measure how well your instance type and Availability Zone flexibility performs, find where capacity is strongest before a scale-up, and add it to Auto Scaling groups, Amazon EC2 Fleet, or Karpenter.

AWS Lambda event source mappings now support queue consumption mode for Apache Kafka. Using Kafka Share Groups, you can scale consumer parallelism independently of partition count, with per-record acknowledgment, visibility timeouts, and automatic retries on self-managed Kafka 4.2 or later clusters.

Durable functions span many Lambda invocations, so per-invocation logs answer the wrong question. The Durable Execution Telemetry Exporter is an SDK plugin that emits one complete record per execution to any of 13 destinations with a one-line change, and a companion MCP server lets an AI agent query that data in plain language.

Run a standard Node.js web server on AWS Lambda with Lambda Web Functions, a new type of Lambda function. Deploy it with one command or AWS CloudFormation and get a public HTTPS endpoint with no adapter layer and no servers to manage. See how one execution environment handles many concurrent requests and how active-CPU billing keeps the cost of waiting low.

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.
