Enhance data and service resilience in Azure Monitor Logs with availability zones

Article
06/05/2023

Azure availability zones protect applications and data from datacenter failures and can enhance the resilience of Azure Monitor features that rely on a Log Analytics workspace. This article describes the data and service resilience benefits Azure Monitor availability zones provide by default to dedicated clusters in supported regions.

Prerequisites

A Log Analytics workspace linked to a dedicated cluster.

Note

Application Insights resources can use availability zones only if they're workspace-based and the workspace uses a dedicated cluster. Classic Application Insights resources can't use availability zones.

Data resilience - supported regions

Availability zones protect your data from datacenter failures by relying on datacenters in different physical locations, equipped with independent power, cooling, and networking.

Azure Monitor currently supports data resilience for availability-zone-enabled dedicated clusters in these regions:

Americas	Europe	Middle East	Africa	Asia Pacific
Brazil South	France Central	Qatar Central	South Africa North	Australia East
Canada Central	Germany West Central	UAE North		Central India
Central US	North Europe			Japan East
East US	Norway East			Korea Central
East US 2	UK South			Southeast Asia
South Central US	West Europe			East Asia
West US 2	Sweden Central
West US 3	Switzerland North
	Poland Central

Service resilience - supported regions

When available in your region, Azure Monitor availability zones enhance your Azure Monitor service resilience automatically. Physical separation and independent infrastructure makes interruption of service availability in your Log Analytics workspace far less likely because the Log Analytics workspace can rely on resources from a different zone.

West US 2
North Europe
