What is an availability zone?
An availability zone is a logical data center in a region available for use by any AWS customer. Each zone in a region has redundant and separate power, networking and connectivity to reduce the likelihood of two zones failing simultaneously. A common misconception is that a single zone equals a single data center.
What is meant by availability zone in AWS?
An Availability Zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region. The network performance is sufficient to accomplish synchronous replication between AZs. AZs make partitioning applications for high availability easy.
What is the difference between availability zone and region?
Each Region is a separate geographic area. Availability Zones are multiple, isolated locations within each Region. Local Zones provide you the ability to place resources, such as compute and storage, in multiple locations closer to your end users.
Which statement best describes an availability zone?

How many availability zones should I use?
High availability requires at least two availability zones. The idea is that only one zone will go down at a time: the proverbial backhoe cutting power and network cables. Since Amazon isolates the data centers for each availability zone, that backhoe won’t take out more than one AZ.
What is availability zone in cloud computing?
Availability zones (AZs) are isolated locations within data center regions from which public cloud services originate and operate. Regions are geographic locations in which public cloud service providers’ data centers reside. Admins can move resources to another availability zone in the event of an outage.

What is availability zones in Azure?
What is an Azure availability zone? Azure availability zones are physically and logically separated datacenters with their own independent power source, network, and cooling. Connected with an extremely low-latency network, they become a building block to delivering high availability applications.
What is the difference between availability zone and availability set?
While availability sets are used to protect applications from hardware failures within an Azure data center, availability zones, protect applications from complete Azure data center failures. An availability zone is a unique physical location that exists within an Azure region.
