To deploy an instance of Azure VMware Solutions, an administrator must take the following two steps:

Create a support request with Microsoft Azure Support to create a host quota.This is required because Azure VMware Solution hosts are dedicated bare-metal servers that are not shared with other customers1.The host quota determines the number and size of hosts that can be provisioned in a subscription1.The host quota can be requested for an eligible Azure plan, such as Microsoft Enterprise Agreement or Cloud Solution Provider2.

Deploy and configure Microsoft Azure ExpressRoute.This is required because Azure VMware Solution uses ExpressRoute to connect the private cloud to the Azure virtual network and the on-premises network3.ExpressRoute provides a secure, high-bandwidth, and low-latency connection that enables seamless workload migration and hybrid cloud scenarios3.The administrator must deploy and configure an ExpressRoute circuit, a virtual network gateway, and a virtual network3.Reference:1: Deploy and configure Azure VMware Solution,2: Plan the Azure VMware Solution deployment,3: Tutorial: Deploy an Azure VMware Solution private cloud
