Availability Zone

An Availability Zone is a geographically separate data center within a cloud provider's infrastructure, such as Amazon Web Services (AWS). Each zone is designed to operate independently with its own power, networking, and cooling. This setup allows organizations to run their applications across multiple zones to improve reliability and fault tolerance. If one zone experiences an issue, others can continue functioning, minimizing downtime and ensuring consistent service. In essence, Availability Zones help ensure your digital services remain available and resilient, even in the face of localized problems or failures.
