What is Azure?

Table of Contents

  • Microsoft’s Cloud Platform
  • It facilitates with all the tools to develop and deploy the applications along with data management irrespective of the regions.
  • Virtualisation Technology is used to provide cloud services.
Compute Services
Web Services

Describe Regions?

A region is a geographic area located anywhere in the world which has at least one data centre but several data-centres at times.

The allocation of services offered in Azure depends on the region selection.

The more number of regions provide great availability along with scalability for the users.


Describe Availability Zones?

Availability Zones are –>Separate Physical Data-centres located with in a region.

Availability Zones
