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.

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.

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.

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.

AWS Local Zones and AWS Outposts help you keep regulated workloads within specific geographic boundaries. This post presents a framework of technologies, including the AWS Nitro System, AWS Organizations SCPs with AWS Control Tower, and Amazon VPC Traffic Mirroring, to help you build auditable, secure architectures for data residency.

Build highly available architectures that span two AWS Outposts racks, or an Outpost rack and an AWS Local Zone, without single points of failure. This post covers three disaster recovery approaches: DNS-based failover, active/active load balancing, and hybrid database replication, with the RTO/RPO trade-offs of each.

Orchestrating specialized Amazon Bedrock AgentCore agents with AWS Step Functions gives you the reasoning power of generative AI with the guardrails of deterministic validation. Agents propose options, and deterministic code validates them before any action is taken, demonstrated here with an airline rebooking workflow.

Learn how to use Amazon EventBridge Scheduler to deliver email campaigns at per-recipient optimal send times. This post shows how to create one schedule per recipient with zero idle compute cost, scale schedule creation with AWS Step Functions Distributed Map, and deliver through Amazon SES.

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.
