I'm Mike Tuszynski. I've spent 25 years building, breaking, and fixing things at scale—from writing code at investment firms to running engineering at a streaming platform to spending six years as a Solutions Architect at AWS. Now I'm a Principal Architect at Presidio, helping enterprises navigate cloud modernization and AI strategy.
The Cloud Codex is where I write about what I've learned in the trenches. Not the sanitized conference-talk version—the real version, with the trade-offs, the failures, and the uncomfortable truths the vendor slides leave out.
What I Write About
-
Cloud Architecture & Infrastructure: Real-world implementations, migration war stories, and why your Kubernetes strategy is probably more fragile than you think. I cover AWS, containers, CI/CD, and the boring-but-critical infrastructure decisions that determine whether your platform survives contact with production.
-
AI & Machine Learning: Strategic analysis of AI hype vs. reality. When to build vs. buy. Why 95% of AI agent projects fail. How to architect ML infrastructure that actually works at enterprise scale—GPU clusters, RAG pipelines, model serving, and the economics nobody discusses.
-
Engineering Leadership: The human side of technical leadership—managing the eng-to-management transition, building teams that ship, and why operational excellence is a feature, not a cost center.
-
DevSecOps: Security that's built in, not bolted on. Automated compliance, quality gates, and the infrastructure patterns that keep you out of the post-mortem room.
Why This Exists
I started The Cloud Codex because I was tired of reading content that's either too shallow to be useful or too vendor-biased to be trustworthy. The best technical writing comes from people who've been accountable for production systems—who've been paged at 3 AM and had to explain outages to executives.
That's the lens I write through. If it helps you make better decisions, avoid a mistake I've already made, or just feel less alone in wondering why everyone else seems to have it figured out—then this site is doing its job.
