Azure Availability Zones
Azure Availability Zones are physically separate locations within an Azure region, each equipped with independent power, cooling, and networking infrastructure. They provide high availability and fault tolerance for applications by allowing deployment across multiple zones to protect against data center-level failures. This feature is designed to ensure business continuity and resilience for mission-critical workloads in the cloud.
Developers should use Azure Availability Zones when building applications that require high availability, such as e-commerce platforms, financial services, or healthcare systems, to minimize downtime and data loss. It is particularly crucial for disaster recovery scenarios, compliance with SLAs (Service Level Agreements), and ensuring redundancy across geographically isolated data centers within the same region. This helps mitigate risks from localized outages like power failures or network issues.
