lambda

ECS CodeDeploy and Lambda aliases support both instant cutover and gradual shifts—but picking wrong costs you double Fargate spend or 21-day MTTR on muted alarms. This decision guide scores blue/green, canary, and rolling with a matrix and names App Mesh (EOL Sept 30, 2026) replacements.

Hardening quick wins: private DMS, OpenSearch encryption, SageMaker VPC-only, Lambda runtime EOL. July 2026 checklist.

AWS CLI v2 #10196 chmod'd streaming outputs to 0600 — including /dev/null. July 2026 retrospective: #10215 revert, host repair, pin-and-canary checklist.

March 2026 roundup — Nova Forge, Durable Functions, Graviton5, Trainium3, Route 53 Global Resolver. July 2026 retrospective: what still matters four months later.

Autoscaling was supposed to make costs predictable by matching capacity to demand. Instead, it introduced feedback loops, burst amplification, and — with AI workloads — a new class of non-deterministic spend that no scaling policy anticipates.

Autoscaling surprise bills are pattern-shaped: asymmetric thresholds, bad metrics, Lambda duration, Spot storms. July 2026 refresh — target tracking, Budget Actions, FinOps Agent.

AWS publishes every price publicly, yet bills still surprise teams in 2026. Costs emerge from service interactions — now including Bedrock/AgentCore — not from any single rate card.

The worst AWS bills still come from small systems with invisible failure modes. July 2026 refresh — SQS/Lambda retry storms, zombie resources, public AI endpoints, and Bedrock/AgentCore spend loops — plus the detection radar.

A technical guide to hybrid compute architectures that combine EC2, Lambda, Fargate, and Step Functions — with worked cost calculations, SQS buffering patterns, and decision frameworks based on invocation pattern rather than unit cost.

Inspector v2 continuously scans EC2, ECR container images, and Lambda functions without agents. Production guide to CI/CD integration, finding management, risk scoring, and multi-account deployment.
