General availability: Azure Availability Zones in select regions

30 March 2018

Azure Availability Zones, a high-availability solution for mission-critical applications, is now generally available.

Availability Zones are physically separate locations within an Azure region. Each Availability Zone consists of one or more datacenters equipped with independent power, cooling, and networking. With the introduction of Availability Zones, we now offer a service-level agreement (SLA) of 99.99% for uptime of virtual machines.

Availability Zones are generally available in select regions.
