Architectural Components of Azure Facts

Question 1

Availability zones

Answer 1

Availability zones include one or more data centers within the same region in different geographical locations. The centers are connected using private fiber-optic networks. Each center can operate on its own if needed so that if one location stops working, the other will continue operations. Not all services can be associated with an availability zone.
Availability zones are not offered in all regions. Azure does maintain a list of regions that currently support availability zones.

Question 1

Regions

Answer 1

These data centers are organized into geographical areas called regions . Each region comprises one or more data centers. Although users may be using resources from multiple locations, they will not notice the regions. However, as an administrator, you may need to select the region where your resources should be deployed. The benefits of these regions include:
Resources can be closer to the user
Load balancing
Scalability
Redundancy
Resiliency

Sometimes, you may need to use one of Azure’s special regions. These are designed specifically to address governmental legal and compliance concerns. These regions may be specific to your state or country.

Question 2

Region pairs

Answer 2

Region pairs are established to provide even further redundancy. If a natural disaster or other event were to impact two or more data centers in the same region, all services would fail over to the region’s pair.

DevOps

Question 13

Resources

Answer 13

Resources are items that can be managed using Azure. This could include:
Virtual machines
SQL databases
Storage
Web apps

Question 14

Resource groups

Answer 14

Resource groups are logical containers for resources. Policies, permissions, and other operations can be applied to the resource group as a whole. Additionally, resource groups can protect resources from being inadvertently deleted.

Question 15

Subscriptions

Answer 15

Subscriptions combine user accounts with the resources that user has created. Each subscription has associated quotas. These quotas limit the total resources a user can use or create.

Question 16

Management groups

Answer 16

Management groups contain one or more resources to be managed and could include:
Virtual machines
SQL databases
Storage
Web apps

Conditions apply to the management group. All subscriptions inherit these conditions within the group.
