Learn how to configure PostgreSQL logical replication between two Amazon RDS for PostgreSQL instances on separate AWS Outposts racks, keeping all replication traffic and backups within your on-premises environment by using Customer-owned IP addresses and Local Gateways, without any data traversing the AWS Region.

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.

Learn how an AWS Lambda function and an Amazon Bedrock AgentCore agent investigate a folder of related documents together through a shared Amazon S3 Files file system, using ordinary file operations instead of object download and upload code.

Amazon EC2 Replace Root Volume with the direct Amazon EBS volume option lets you prepare and validate a replacement root volume in advance, then swap it onto a running production instance with a single reboot. Learn how to upgrade the OS and apply patches while the instance keeps its production identity, including instances in Auto Scaling groups.

Learn how to build a five-step Agent Engine Optimization (AEO) scoring pipeline on AWS Lambda durable functions. Each checkpointed step suspends without incurring costs between stages and retries without re-spending on prior work, so you can score any page against five AEO signals and deploy the solution with an AWS SAM template.

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.

Lambda durable functions checkpoint execution state to durable storage, and for regulated payment workloads that data is sensitive. This post shows how to configure a customer managed key in AWS KMS to encrypt durable execution data, define a least-privilege key policy, and verify encryption through AWS CloudTrail, all deployed with Terraform.

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.

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.

Many teams want to expose their AWS Lambda MicroVMs under a custom domain they own, and satisfy CORS for browser clients, without changing the application. This post shows how, using an Application Load Balancer that rewrites the Host header and forwards over AWS PrivateLink, deployed with the AWS CDK.
