Customers can deploy an internal load balancer (ILB) ASEs into a specific AZ within an Azure region. Both website file content as well as customer supplied settings and secrets stored in App Service remain within the region where the zonal ILB ASE is deployed. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. I use classic Service Plan (not ASE). Customers can choose to optionally deploy internal load balancer (ILB) ASEs into a specific AZ (Zone 1, 2 or 3) within an Azure region, and the resources used by that ILB ASE will either be pinned to the specified AZ, or deployed in a zone redundant manner. They are not designed to support Availability Zones (although Azure conducts regular assessment of these regions to determine if they should become recommended regions). 99.99% VM uptime SLA is offered when two or more VMs are deployed across two or more Availability Zones within an Azure region. We need the same SLA for the app services otherwise our overall site availability will be limited by the App Service SLA. Each cluster hasindependent software infrastructure, power, cooling, network, and securityinfrastructure, and includes a large pool of compute and storage resources.Each zone is hosted in one or more clusters and Compute Engineindependently maps zones to clusters for each organization. Very simple question, please give a simple answer. Zonal ILB ASEs can be created in any of the following regions: Applications deployed on a zonal ILB ASE will continue to run and serve traffic on that ASE even if other zones in the same region suffer an outage.
