The core architectural components of Azure.

In this summary, I'm just going to quickly wizz through the four core components of Azure and this includes paired regions, Availability Zones, resource groups, and the Azure Resource Manager.

The Paired Regions
Azure data centers operates all over the world, in many different locations and regions. This regions are referred to an area within a geography that contains one or more data centers. Regional pairs allow Azure to divide platform updates and planned maintenance. This ensures that only one paired region is updated at a given time. This ensure optimal application availability and minimizes recovery time in the event of a disaster occurring.

Availability Zones
Availability zones offers to protect applications and data centers from data center failures. Each Availability Zone is a unique physical location within an Azure region, and each zone is supported by one or more data centers, equipped with their own independent power, cooling, and networking infrastructure. Availability Zones helps to ensure resiliency in each enabled Azure region.

Azure Resource Groups
The Resource group is like a folder that is used to host all resources that comprise an overall Azure solution or the resources that need to be managed as part of a group. The administrator gets to decide, based on needs, how to allocate resources in resource groups within Azure. Also resources from multiple resources group can interact with each other.

Azure Resource Manager
Resource Manager provides a consistent management layer for all Azure resources, security and auditing features, as well as tagging features that you can use to manage your resources once they’ve been deployed into Azure. Using Resource Manager, you can deploy, manage, and monitor all Azure resources for a solution as one group.
