Validate Azure Zone Redundancy with az zones CLI
Reliability (Resiliency, availability, recovery) is part of one of the main pillars of the Azure Well-Architected Framework. It is essential for ensuring that applications and services remain operational and performant, even in the face of failures or unexpected events. Reliability encompasses various aspects, including fault tolerance, disaster recovery, and high availability.
Reliability is also a shared responsibility between the cloud provider (ie, Microsoft) and the customer. While Azure provides a robust infrastructure and services designed for reliability, customers must also implement best practices and strategies to ensure their applications are resilient and can recover from failures.
But a key question arises: How do we check the reliability (in this example, Zone redundancy of our Workload) ?
One of the tools we can use for this is the az zones
command line tool.
