Before deploying anything in Azure, every cloud administrator must understand regions, availability zones, and region pairs. These concepts define how Azure ensures high availability and reliability.
What does an Azure Cloud Administrator actually do every day? From fixing production outages to managing infrastructure, here is a real-world look at the job.
Traces, metrics, logs — the three pillars and the fourth nobody talks about: profiling. How to instrument distributed systems so you can debug them when they fail at 3am.
At-least-once vs exactly-once delivery, dead letter queues, consumer groups, and idempotency — the complete mental model for building reliable event-driven systems.
Raft, Paxos, Viewstamped Replication — not as academic exercises but as practical mental models for understanding what your databases actually guarantee.
Why wall clocks lie in distributed systems, how logical clocks restore causality, and the precise guarantees you can and cannot rely on when reasoning about event ordering.
