Availability zones are separated groups of data centers within a region that have independent power, cooling, and networking infrastructure. They're close enough to have low-latency connections to other availability zones but far enough to reduce the possibility that more than one is affected by local outages or weather. See [What are availability zones?](../reliability/availability-zones-overview.md) for details.

Multiple VMs have the highest [SLA](https://www.microsoft.com/licensing/docs/view/Service-Level-Agreements-SLA-for-Online-Services?lang=1) when deployed across three availability zones. For VMs and disks deployed across multiple availability zones, the disks and their parent VMs are respectively collocated in the same zone, which prevents multiple VMs from going down even if an entire zone experiences an outage. Availability zones aren't currently available in every region, see [Azure regions with availability zone support](../reliability/availability-zones-service-support.md#azure-regions-with-availability-zone-support).

Multiple VMs have the highest [SLA](https://www.microsoft.com/licensing/docs/view/Service-Level-Agreements-SLA-for-Online-Services?lang=1) when distributed across three availability zones. For VMs and disks distributed across multiple availability zones, the disks and their parent VMs are respectively collocated in the same zone, which prevents multiple VMs from going down even if an entire zone experiences an outage.

VMs deployed across multiple availability zones may have higher network latency than VMs deployed in a single availability zone, which could be a concern for workloads that require ultra-low latency. If low latency is your top priority, consider the methods described in [Deploy VMs and disks across multiple fault domains](#deploy-vms-and-disks-across-multiple-fault-domains).

To deploy resources across availability zones, you can either use [zone-redundant Virtual Machine Scale Sets](#use-zone-redundant-virtual-machine-scale-sets-with-flexible-orchestration) or [deploy resources across availability zones](#deploy-vms-and-disks-across-three-availability-zones).
