Cloud Architecture

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.

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.

How to evaluate AWS consultants vs Partners: certs, red flags, SOW questions. July 2026 scorecard for freelancer vs agency vs Partner.

Not every company needs an AWS MSP — but many are past the point in 2026. Ten signs it is time, updated for Business Support+ vs MSP and GenAI ops gaps.

Most AWS MSP pitches are still vague in 2026. Concrete day-to-day scope — CloudWatch Application Signals, FinOps, patching, incident response — plus what stays out of a standard SOW (including GenAI/AgentCore unless named).

Business Support+ and an AWS MSP still sound similar in July 2026 — they are not. Current Support tiers (post 2025-12-02 restructure) vs MSP scope, cost, and when you need both.

Choosing an AWS managed services provider is still a 1–3 year commitment in 2026. Updated RFP framework — monitoring (including Application Signals), FinOps evidence, GenAI ops boundaries, SLA remedies, and exit terms.

Companies still skip 24/7 AWS monitoring to save money. As of July 2026 the math is unchanged — downtime, churn, and runaway Lambda/NAT spend almost always cost more than human-backed response. CloudWatch alarms alone are not coverage.
