Welcome to TechEn

This blog is where I document how infrastructure actually gets built,
upgraded, and kept running — the parts that don't make it into vendor
documentation.

If you work with clouds, clusters, pipelines, or the occasional
3 a.m. incident, you'll feel at home here.

What You'll Find Here

• Cloud & Private Cloud — VMware Cloud Foundation, vSphere, vSAN, NSX: design choices, upgrade runbooks, and the trade-offs nobody mentions in launch blogs
• DevOps — CI/CD pipelines, Kubernetes platforms, GitOps, and the automation glue that holds estates together
• AI in Production — private AI stacks, GPU scheduling, and what it takes to run inference next to your databases
• Honest Debriefs — what broke, what I'd do differently, and the configs that actually shipped

Why Another Tech Blog?

Because most content stops at the happy path. The interesting engineering
is in the upgrade that half-failed, the sizing assumption that fell apart
at scale, and the feature that sounds great until you read the fine print.

Every post here comes from hands on keyboards — production evidence over
marketing slides.

Start Here

The archive is already warm:

• What's New in VMware Cloud Foundation 9.1 — The Deep Dive — NVMe memory tiering, zero-touch provisioning, live patching, and the private AI push, all broken down
• Coming next: a VCF 9.0 → 9.1 upgrade runbook and an NVMe memory tiering benchmark series

[!NOTE]
The site itself runs on Next.js 15 with a custom arc-reactor interface —
click the reactor in the hero, it's interactive.

Stay in the Loop

New posts land in the archive as they're published, and
search indexes everything. Bookmark both — the workshop stays busy.
