Before a partner-led WA Review, a fintech workload with 23 open HRIs spent 6 weeks on unfocused fixes; after the readiness checklist and HRI cap of 5 for 90 days, the next milestone dropped High Risk items from 23 to 7 in one review cycle.

A stack of ALB + EC2 + RDS Multi-AZ + S3 composes to ~99.83% availability—so promising customers 99.9% is a check you cannot cash. This guide does the composition math, converts it to an error budget (99.9% = 43.2 min/month), and shows why AWS service credits never fund your SLA penalties.

A CCoE that only publishes standards decks fails within two quarters. This 2026 operating model ties platform RFCs, delegated-admin guardrails, Well-Architected reviews, and FinOps chargeback—benchmarked on a 14-account estate that cut deploy exceptions from 23/month to 6 in 90 days.

CAF 3.0 organizes six perspectives and 47 capabilities—up from 31 in CAF 2.0—plus four phases (Envision, Align, Launch, Scale). Here is how to connect those workshops to Control Tower, MAP, and Well-Architected without treating the framework as a slide deck.

Anton Babenko's Terraform Claude Skill is the biggest jump in AI-assisted IaC since Copilot. We tested it on a real AWS stack — VPC, EKS, S3 + KMS, IAM — and documented exactly what it fixes, what it misses, and what AWS teams should layer on top.

The most expensive AWS architectures are not the ones that use the most resources — they are the ones whose costs respond unpredictably to inputs. This is the design discipline for building systems where costs are structurally bounded and forecasting is accurate.

Well-Architected reviews used to read like AWS sales decks. The 2026 version is sharper. The 6 pillars walked through with what each costs, what each covers, and how to apply them to a workload before AWS's solutions architects do it for you.
