AWS architecture patterns covering microservices vs monolith decisions, multi-tenancy, serverless design, database selection, and multi-account governance. Frameworks drawn from real enterprise and SaaS architecture engagements.
MAP Mobilize should not start with more than five failed controls in Platform or Security. This 47-point readiness checklist (People, Platform, Security, FinOps) is the auditable artifact we attach to Assess-phase business cases—aligned to CAF 3.0 and the Migration Lens, not generic cloud maturity fluff.
A first-person, opinionated 2026 AWS learning path. Built around 6 phases, anchored to a 3-month full-time benchmark, and explicit about which cert (Cloud Practitioner) to skip and why.
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.
Global Accelerator charges about $0.025 per provisioned accelerator per hour—even while disabled—and adds Data Transfer-Premium on top of normal data transfer. Two static Anycast IPv4 addresses (or four addresses in dual-stack: two IPv4 and two IPv6) front ALBs, NLBs, EC2, or EIPs across Regions; that pricing model changes whether you beat CloudFront or Route 53 latency records alone.
Aurora storage replication is cross-AZ by design; writer failover targets typically complete in tens of seconds—plan application timeouts above that window or you ship self-inflicted outage amplification every failover drill.
Standard SQS queues sustain nearly unlimited throughput per queue (AWS-documented pattern) while FIFO caps at 300 TPS per API batch without high-throughput mode—your May 2026 architecture review should start from those numbers, not from Kafka slogans.
API Gateway REST APIs cap integration timeouts at 29 seconds; WebSocket APIs bill per message and connection minutes—your May 2026 API design should bake those numbers into SLO tables before picking protocols.
As of May 8, 2026, Lambda bills INIT time on cold paths (pricing change live since Aug 1, 2025), API Gateway REST integrations time out at 29 seconds, and picking ALB vs NLB still determines whether TLS termination and routing live on the edge.
CloudWatch Logs Insights bills $0.005 per GB scanned and high-cardinality custom metrics multiply costs. Cardinality budgets, sampling rules, and FinOps fixes.
API Gateway REST integrations still max out at 29 seconds—if your Lambda keeps retrying a 35-second partner HTTP call without a bounded circuit, you burn capacity and duplicate side effects instead of failing fast.
Nine recurring program mistakes still show up in 2026 reviews—especially after AWS closed Migration Hub to new customers on November 7, 2025. Practical fixes tied to AMS (MGN), DMS, AWS Transform, Org/SCPs, FinOps bubble costs, and the Migration Lens checklist.
A curated, production-tested guide to microservices patterns on AWS — what to use, what to skip, and what changed in 2026 (App Mesh EOL, VPC Lattice, Powertools idempotency, Step Functions sagas).
