RDS performance: gp3 IOPS, Performance Insights / Database Insights, Proxy, replicas, ElastiCache. July 2026 tuning checklist.

AWS Graviton processors deliver 20-40% cost savings and better performance-per-watt. Complete guide: migration path, performance benchmarks, and production deployment patterns.

A technical deep dive into EC2 performance optimization for API workloads — covering instance family selection, Graviton vs x86 economics, network tuning, EBS configuration, and Linux kernel parameters that directly impact throughput and tail latency.

Atlas vs EC2 vs DocumentDB on AWS — TCO flips with DBA time, not $/vCPU. July 2026: index/cache pressure, hot shards, DocumentDB API-compat caveat.

Pick runtimes by ECS density and team skills — not synthetic RPS. July 2026: FrankenPHP worker vs PHP-FPM, Node, Go memory bands + density matrix.

ECS concurrency: PHP-FPM vs Octane, Node event-loop lag, Gunicorn/asyncio, Go goroutines. July 2026 matrix + ulimit checklist.

Vite 8 (March 2026) ships Rolldown by default. July 2026: Bun install, SWC, CodeBuild cache — cut CI build minutes.

Most auto-scaling configs end up reactive — scaling after load hits, not before. The patterns that anticipate demand instead of chasing it across EC2, ECS, and Lambda, with the cost trade-offs of target tracking, step scaling, and predictive scaling.

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.

Redis is fast — until your application retries on every cache miss and the Redis bill starts looking like the database bill. ElastiCache patterns, data structures, cluster modes, eviction policies, and the production patterns that actually reduce database load.
