AZ-900 – Describe regions and availability zone

Mark May 23, 2020

I am currently studying for the AZ-900 Fundamentals exam, I have been working with Azure for a couple of years now coming from a VMware background most of the concepts around Virtual machines, storage and networking makes sense without much additional study.

Learning the Azure terminologies, can at times be like learning a new language. I have created the below diagram to help understand and be able to describe regions and availability zones: –

Notes

Geography is a market, typically containing two or more regions, that preserves data residency and compliance boundaries. For the UK would look at a Geography (Europe) which would allow complying with GDPR (unless Brexit changes this)

A region is a set of datacenters within a latency-defined perimeter connected through a dedicated regional low-latency network. 

Availability Zones are physically separate datacentres with in an Azure region, with independent power, network and cooling. 

There are a couple of great resources I am currently using, to help study for the exam: –
