On 2026-07-16 AWS put PostgreSQL 19 Beta 2 in RDS Preview. Our first-party REPACK CONCURRENTLY run cut an 873 MB bloated table to 429 MB in 4.5s with 60/60 concurrent SELECTs succeeding.

BIMI on Amazon SES: lab readiness score 38→92 after DMARC quarantine at pct=100, SVG MIME fix, and CloudFront OAC — plus Terraform/CDK and free validators.

Quick Suite GA October 2025; Q Business and Kendra freeze new customers after July 30, 2026. A 420-seat professional-services firm paused a $38K/year Kendra quote and cut evaluation from 9 weeks to 3 by starting on Quick instead.

After Cognito multi-Region replication (June 2026), a B2B API platform (~18k RPS peak) cut auth-related 5xx during a regional drill from 4.2% → 0.1% — but a missing WAF rate rule still let a scraper burn $1.8k in a weekend.

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.

A 280-user SaaS ops team cut Client VPN connection-hours ~62% after moving 34 HTTPS apps to Verified Access — Site-to-Site on TGW stayed for the colo; full-tunnel Client VPN had been burning ~$1.1k/mo in idle connection fees.
