At 2:47 AM, an on-call engineer gets paged: CPU on a production Amazon EC2 instance has been above 95% for five minutes. They open Amazon CloudWatch and run the usual triage, checking recent deployments, traffic spikes, memory, and disk I/O. Nothing lines up. They scale the instance; utilization climbs back within minutes. Thirty-two minutes later, […]

For airlines running passenger-facing and operational workloads on AWS, infrastructure availability and performance translate directly into on-time departures, revenue, and passenger trust. A reservation system that stalls during a fare sale, a check-in platform that slows on a peak holiday morning, or a security incident targeting passenger data can ripple across an entire network of […]

A zero-infrastructure  AWS DevOps Agent skill profiles your Amazon CloudWatch Logs estate and gives you one view of it. CloudWatch Logs already captures the signals you need to operate it well, including how each log group is classed, how long it is kept, who reads it, where its data flows, and how fast it grows. […]

AWS CloudTrail now includes a Data event coverage page in the AWS CloudTrail console, giving you a single view of how well your resources are covered by data event logging. CloudTrail records API activity across your AWS account for security auditing, compliance, and operational troubleshooting. Management events, the control-plane actions such as creating a bucket […]

Starting today, you can manage resource tags in bulk in the AWS Resource Explorer console, and requests to Tag Editor console will redirect to Resource Explorer automatically. This post shows how each Tag Editor task works in Resource Explorer and where the steps differ. Benefits of tagging resources in Resource Explorer. Finding resources and tagging […]

AWS DevOps Agent investigates incidents, traces problems from code to cloud, and analyzes Amazon CloudWatch, AWS CloudTrail, and third-party observability tools out of the box. But every operations team carries knowledge the agent cannot reach through generic reasoning: the order you check things in when, for example, an Amazon Elastic Container Service (ECS) task won’t […]

Telemetry volume and incident counts keep growing while operations headcount stays flat, and coding tools now produce changes faster than most release processes can review them. The AIOps topic on the re:Invent 2026 Cloud Operations (COP) track covers how AI agents handle operational work: investigating incidents, recommending fixes, reviews code changes to catch issues before […]

As organizations continue to scale their cloud presence and bring AI agents into production, effective operations become increasingly critical for success. The AWS re:Invent 2026 Cloud Operations track brings together industry experts, AWS leaders, and customers to share how they modernize monitoring and observability for applications and the AI agents now running alongside them. This […]

1. Introduction A pod on your Amazon Elastic Kubernetes Service (Amazon EKS) cluster is restarting on a memory limit. An automated agent spots it, doubles the memory, and syncs the application. On a quiet afternoon that is a tidy self healing story. During a release window, or on a service that is mid rollout, the […]
