About

AlexSite is a small technical notebook by Alex Mao, an Azure cloud operations engineer who works close to the practical edge of cloud reliability.

The site focuses on operational thinking: landing zones, identity boundaries, network patterns, automation habits, backup assumptions, observability, and the quiet engineering decisions that keep cloud platforms predictable after the initial deployment is finished.

Alex writes for people who need useful infrastructure notes without ceremony. The goal is to capture what survives real environments: clear defaults, simple runbooks, and designs that are easy to explain during an incident.

Topics

• Azure landing zones and governance
• Cloud operations and incident response
• Identity, networking, and security baselines
• Automation with practical guardrails
• Notes from maintaining small, reliable systems

This is intentionally a lightweight site: mostly essays, checklists, and field notes.
