Reinforcement learning at scale runs thousands of isolated rollout sandboxes in parallel, and packing more of them onto each host lowers your cost per training step. This post shows how to tune Firecracker microVM density on Amazon EC2 metal, and introduces labsweep, a harness for mapping your own latency and density curve.

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.

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.

Learn a serverless, two-account pattern for running regulated, air-gapped RHEL-family fleets on AWS. It separates connected package ingestion from the air-gapped workload, adds explicit human approval for package changes, and keeps EC2 Image Builder AMIs and Patch Manager on one frozen Amazon S3 repository snapshot.

Multi-modal autoscaling with Amazon EC2 Auto Scaling combines infrastructure metrics like CPU with application-level signals, so a group scales on the demand its users create. In this post, we show you how to implement it, with code samples and results from a controlled test.

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.

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.

Online multiplayer gaming continues to grow, with players demanding lower latency, higher concurrency, and more immersive experiences than ever before. For game studios hosting dedicated multiplayer servers on AWS, infrastructure decisions directly impact player experience and retention, server tick rates, and ultimately, revenue. Games are becoming more computationally demanding while offering richer gameplay experiences. Studios […]

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 […]
