Cloud Architecture

For an on-prem MySQL estate (~1.1 TB, 340 tables), DMS full load + CDC into Aurora MySQL cut planned downtime from 6h → 18 min — LOB misconfiguration added 11 hours of rework before cutover.

For a mid-market retailer (~2.4M SKUs, checkout p95 1.9s → 420ms), DynamoDB cart + Step Functions checkout + conditional inventory cuts held 2.1k checkout RPS — after a cache-as-inventory mistake oversold 380 units in 12 minutes.

For a .NET monolith (~220 endpoints, ~$28k/mo EC2), strangling 14 endpoints to Lambda cut p95 on those routes 1.4s → 210ms — an early LMI move on spiky traffic wasted ~$3.2k in idle capacity provider hours.

For a multi-district LMS (~52k concurrent exam submissions in 30 min), SQS decouple + Aurora Serverless v2 held p95 submit at 410 ms — off-peak monthly compute −71% vs always-on EC2.

For a card-acquiring fintech (~12M authorizations/mo), Payment Cryptography + PCI-scoped account cut HSM rack lease −$18k/mo — fraud review queue p95 2.4s → 380ms after EventBridge Pipes idempotency fix.

For an enterprise lake (~38 TB Iceberg, 8.4k small files), S3 Tables managed compaction cut Athena scan spend −35% — compaction OPEX −90% vs pre–July 2025 pricing on the same workload.

For a multi-clinic digital health platform (~2.4M FHIR resources, 180 TB imaging), HealthLake + HealthImaging cut CCDA-to-FHIR onboarding from 14 weeks to 9 days — query latency p95 820 ms → 190 ms on clinical dashboards.

For a regional PropTech platform (~420k listings, 38 MLS connectors), DynamoDB canonical store + OpenSearch geo cut median search latency from 340 ms to 48 ms — image CDN cost −62% with Intelligent-Tiering.

Q2 2026 ranked: AgentCore Harness GA (Jun 17), FinOps Agent preview (Jun 9), Graviton5 GA (Jun 10), OpenAI on Bedrock (Apr 28). Adoption matrix + verified TCO signals for CTOs.

For a fintech SaaS (6 prod databases, ~$14k/mo RDS line), scoping in-house DBA for schema + MSP for 24/7 paging cut on-call from 22 to 9 hrs/mo — Aurora Serverless v2 min ACU tuning handled tier-2 first.

For discrete manufacturing (~850 OPC-UA tags, 12 lines), Greengrass + IoT SiteWise anomaly detection moved OEE from 61% to 74% in 90 days — unplanned downtime −18% without replacing MES.

For a mid-market software estate (~280 VMs, $340k/yr Broadcom renewal), splitting 60% MGN rehost + 25% EVS relocate + 15% replatform cut parallel-run from 22 to 16 weeks — without forcing one hypervisor strategy.
