# Microsoft Azure Cloud Configuration

If your public cloud provider is Microsoft Azure Cloud, you need to [**Create an ExpressRoute Circuit**](https://learn.microsoft.com/en-us/azure/expressroute/expressroute-howto-circuit-portal-resource-manager?pivots=expressroute-current#create) first on Azure Cloud console, generate a **service key** and share it to Zenlayer. The general steps are listed below.

## Prerequisites

1. Zenlayer support service providers like [**Equinix**](https://www.equinix.com/partners/microsoft-azure/) and [**Megaport**](https://www.megaport.com/services/microsoft-expressroute/). View [**available locations**](https://learn.microsoft.com/en-us/azure/expressroute/expressroute-locations#global-commercial-azure) supported by these providers.
2. Your ExpressRoute circuit is billed from the moment a service key is issued. Ensure that you perform this operation when the connectivity provider is ready to provision the circuit.

## **On Azure Cloud Console**

1. [**Create an ExpressRoute circuit**](https://learn.microsoft.com/en-us/azure/expressroute/expressroute-howto-circuit-portal-resource-manager?pivots=expressroute-current#create)
2. View the properties to find the **Service Key**.

* [**Layer 3 connection**](/welcome/cloud-networking/get-started/create-a-layer-3-connection/select-a-public-cloud-as-access-point.md)

## **Go Back to Azure Cloud Console**

1. [**Connect a virtual network to your ExpressRoute circuit**](https://learn.microsoft.com/en-us/azure/expressroute/expressroute-howto-linkvnet-portal-resource-manager?pivots=expressroute-current)
2. [**Configure a virtual network gateway for your ExpressRoute circuit**](https://learn.microsoft.com/en-us/azure/expressroute/expressroute-howto-add-gateway-portal-resource-manager)
