Insights & Resources

AWS cost problems grow undetected for organizational reasons. Engineers make architectural decisions with no cost feedback. Finance sees bills 30 days late. No one owns the gap between the two.

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

AWS publishes every price publicly, yet bills still surprise teams in 2026. Costs emerge from service interactions, now including Bedrock/AgentCore, so no single rate card shows the total.

S3 storage is still cheap in July 2026. Request storms, unmanaged versioning, CRR, Express One Zone, and S3 Tables compaction choices are what blow the bill, more than GB-month does.

The worst AWS bills still come from small systems with invisible failure modes. July 2026 refresh: SQS/Lambda retry storms, zombie resources, public AI endpoints, and Bedrock/AgentCore spend loops, plus the detection radar.

CI/CD infrastructure is invisible until your DevOps bill hits $15,000/month. Build minutes, artifact storage, and ephemeral environments accumulate costs that few teams track. This post covers how to measure and control them.

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 500ms latency spike in a distributed system could be a slow RDS query, a Lambda cold start, a downstream API timeout, or a CloudWatch Logs ingestion delay. Finding the cause requires correlated logs, traces, and metrics, not grep.

A technical guide to EC2 performance optimization for API workloads: instance family selection, Graviton vs x86 economics, network tuning, EBS configuration, and the Linux kernel parameters that affect throughput and tail latency.

RDS, Aurora, and self-managed Postgres each have a cost breakeven point. This guide covers total cost of ownership, connection pooling with PgBouncer, indexing strategies, and the edge cases that turn Postgres into a billing surprise.

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 that start from the invocation pattern instead of unit cost.

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.
