Cloud Architecture

Migration TCO tools nail steady-state and miss the gap: dual-run weeks, DMS, DC egress, day-1 Config/GuardDuty. July 2026 — dual-run worksheet + MAP tagging note.

A B2B SaaS stack that costs $500/month at launch does not need to cost $50,000/month at 100,000 users if the architecture decisions at each stage are deliberate. This is the end-to-end reference architecture with real cost numbers.

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.

A technical guide to hybrid compute architectures that combine EC2, Lambda, Fargate, and Step Functions — with worked cost calculations, SQS buffering patterns, and decision frameworks based on invocation pattern rather than unit cost.

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.

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

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.
