July 2026: Route 53 hosted zones, latency/geo/failover routing, health checks, and when DNS TTL is not enough, with Route 53 Application Recovery Controller for controlled multi-Region cutover.

Least privilege is easy to say and harder to run at production scale. This covers roles vs users, permission boundaries, SCPs, identity federation, and the access-control patterns that keep teams fast without leaving keys lying around.

The 6 Well-Architected pillars, with what each costs, what each covers, and how to apply them to a workload before AWS's solutions architects do it for you.

Most auto-scaling configs end up reactive: they scale after load hits, not before. This covers the patterns that anticipate demand across EC2, ECS, and Lambda, with the cost trade-offs of target tracking, step scaling, and predictive scaling.

Secrets Manager rotates and costs $0.40 per secret per month. Parameter Store doesn't rotate and is mostly free. Pricing, rotation, encryption, cross-account access, and the decision criteria for picking each, including the hybrid pattern most production accounts end up at.

SQS is "reliable" only if you understand visibility timeout, dead-letter queues, and the silent failure mode where messages get processed twice. Standard vs FIFO, DLQ tuning, Lambda integration, and the patterns that make SQS reliable beyond its default settings.

Migrating from SendGrid to SES is mostly cheap, until your warm-up plan is wrong and deliverability falls off a cliff. This covers DNS cutover, IP warming, API surface differences, and the deliverability checkpoints that keep email landing in inboxes through the switch.

A VPC misdesign at month two becomes a multi-quarter migration at year two. CIDR planning, subnet strategies, NAT gateways, VPC endpoints, Transit Gateway, and the network architecture patterns that scale without forcing a re-IP.

June 30, 2026 added two major CloudFormation/CDK changes: pre-deployment validation on Create/Update and Express mode with up to 4x faster stack operations. This guide covers when to use each in production workflows.

July 2026: Trainium2 (trn2.48xlarge, 3.2 Tbps EFA) and Inferentia2 via Neuron SDK. AWS cites ~30-40% better price performance vs P5e/P5en; measure your workload before quoting wider savings.

July 2026: CloudFront (750+ POPs, Origin Shield, Functions vs Lambda@Edge) vs Cloudflare (proxy + unmetered egress). Decide with a worksheet, not a stale POP count slide.

July 2026 decision guide: monolith → modular monolith → microservices on AWS, covering team size, platform tax (VPC Lattice/mesh), and a checklist before you split for the org chart.
