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.

The primary storage solutions for EC2 Windows instances, Amazon EC2 Instance Store and Amazon Elastic Block Store (Amazon EBS) , now provide detailed performance statistics for real-time monitoring. Real-time monitoring enables you to gain visibility into key performance metrics, such as latency, throughput, and IOPS, allowing you to detect and address potential bottlenecks or issues […]

When you create an AWS Lambda function, you choose the runtime that Lambda will use to run your code. This includes the base language version and supporting libraries. Lambda runtimes follow a published deprecation schedule. This means that you must periodically upgrade your function’s runtime. Running on a deprecated runtime means potential security exposure, loss […]

When downsizing an Amazon Elastic Compute Cloud (Amazon EC2) instance, teams often evaluate CPU and memory utilization but overlook the instance’s Amazon Elastic Block Store (Amazon EBS) performance limits for throughput and IOPS. Smaller Amazon EBS-optimized instance types have lower baselines and rely on burst credits to handle peaks. If your workload’s I/O pattern drains […]

Building event-driven multi-tenant SaaS applications typically requires compute isolation between tenants to prevent data leakage, maintain security boundaries, and ensure compliance. Traditionally, you had to choose between two approaches: sharing execution environments across tenants (risking cross-tenant contamination of in-memory state) or managing separate Lambda functions per tenant (which introduces operational overhead, increasing costs, and complicating […]
