-Microsoft offers multiple ExpressRoute peering locations in many geopolitical regions. For maximum resiliency, Microsoft recommends that you establish connection to two ExpressRoute circuits in two peering locations. If ExpressRoute Metro is available with your service provider and in your preferred peering location, you can achieve a higher level of resiliency compared to a standard ExpressRoute circuit. For non-production and non-critical workloads, you can achieve standard resiliency by connecting to a single ExpressRoute circuit that offers redundant connections within a single peering location. The Azure portal provides a guided experience to help you create a resilient ExpressRoute configuration. For Azure PowerShell, CLI, ARM template, Terraform, and Bicep, maximum resiliency can be achieved by creating a second ExpressRoute circuit in a different ExpressRoute location and establishing a connection to it.
