Exploring AWS Lambda Web Functions for building web applications
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.
Introducing EC2 AMI Tag Sharing: Share EC2 tags across AWS accounts
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.
Simplify AMI discovery with Amazon EC2 and SSM Parameter Store
Managing Amazon EC2 AMIs at scale means constantly mapping AMI IDs to their AWS Systems Manager parameter paths by hand. A recent enhancement to the DescribeImages API returns the associated SSM parameter directly. This post shows how to use it across the AWS CLI, AWS CloudFormation, Terraform, and Auto Scaling launch templates.
Improving Lambda function latency with scalable network bandwidth
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.
Customize Amazon API Gateway destinations for execution logs
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 […]
Bring your own client certificate for backend mTLS in Amazon API Gateway
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.
Set up your AI coding agent to build with AWS Step Functions
AWS Step Functions has added a Copy agent prompt button to the console that configures your AI coding agent with Step Functions skills and an MCP server in one step. Paste the prompt into Claude Code, Kiro CLI, Cursor, or any MCP-compatible agent and start building workflows with natural language.
Designing for failure: Building resilient systems on AWS
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.
Build high-performance apps with AWS Lambda Managed Instances
In this post, you will learn how to configure AWS Lambda Managed Instances by creating a Capacity Provider that defines your compute infrastructure, associating your Lambda function with that provider, and publishing a function version to provision the execution environments. We will conclude with production best practices including scaling strategies, thread safety, and observability for reliable performance.
Best practices for Lambda durable functions using a fraud detection example
This post walks through a fraud detection system built with durable functions. It also highlights the best practices that you can apply to your own production workflows, from approval processes to data pipelines to AI agent orchestration.
