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.

Multi-region AWS architectures can easily cost 2–3× a single-region equivalent when data replication, cross-region transfer, and duplicated managed services are not accounted for. Here is how to architect for resilience without proportional cost growth.

SQS is cheap until retry storms: short polling × uncapped workers. July 2026 — long poll 20s, visibility math, DLQ alarms, concurrency caps.

A deep technical guide to running PHP, Python, and Node.js applications on Amazon ECS in production — covering Fargate vs EC2, FrankenPHP vs Nginx+FPM, multi-container task patterns, zero-downtime deployments, and observability.

Billing attacks: CloudFront request floods, Lambda bombs, SQS/SNS OTP spam. July 2026 — WAF ceilings, reserved concurrency, Budgets Actions, FinOps backstops.

Valkey on ElastiCache: about 20% node / 33% serverless cheaper than Redis OSS engines. July 2026 — sessions, rate limits, locks, migration checklist.

SQS, MSK Kafka, and Redis queues are not interchangeable. Each has different cost models, ordering guarantees, and failure modes. This guide covers when to use each, how to autoscale workers on queue depth, and how to build idempotent consumers.

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.

Refactor, replatform, or rearchitect — pick the path that matches value and risk. July 2026 refresh: 6R framing, AWS Transform for mainframe, when strangler fig fails.

MAP still offsets dual-run migration cost — if you qualify and tag correctly. July 2026 SMB guide: Assess→Mobilize→Migrate, MAP 2.0 tagging, partner-confirmed ARR tiers (not self-serve credits).

The difference between a successful AWS migration and a costly failure often comes down to strategy. A practical guide to choosing the right migration approach, building your roadmap, and avoiding the pitfalls that derail most projects.
