An Availability Zone in cloud computing is a distinct location within a cloud provider's region that is insulated from failures in other zones. Each Availability Zone provides redundant, low-latency network connectivity to other zones in the same region, making them an important part of a cloud provider's disaster recovery strategy.
Availability Zones work by providing a separate location for data and applications within a cloud provider's region. Each zone is designed to be isolated from failures in other zones, and they're connected through low-latency links.
A cloud service provider, CloudServe, offers several Availability Zones in each of their regions. A customer, DataCorp, distributes their applications and data across these zones. When one zone experiences a failure, DataCorp's applications and data are quickly moved to another zone, minimizing downtime and data loss.
A characteristic of a system which aims to ensure an agreed level of performance, usually uptime, for a higher than normal period.
Resources in a cloud platform that are tied to a specific zone (Availability Zone) and can't be used or accessed outside of that zone.
