Cross-Cloud Interconnect lets you establish a dedicated physical connection between Google Cloud and Microsoft Azure networks.
Google provisions this physical connection on your behalf. However, as part of the setup process, you must complete several tasks. You complete some tasks before Google provisions your connection and some tasks afterward.
These tasks include the following:
- Choose your locations
Identify locations for your primary and redundant Cross-Cloud Interconnect and Azure ports. Make a note of the location names. You need these details to complete the ordering and configuration processes.
Cross-Cloud Interconnect connections
Place an order for two Cross-Cloud Interconnect connections—a primary connection and a redundant one. In response, Google reserves two ports for you in the facility that you specify. For each port, we send you a confirmation email that contains instructions related to the next step: ordering your Azure ports.
Order your Azure ports, and download the corresponding letter of authorization (LOA). This document confirms your right to use the ports. Send the LOA to Google, following the instructions from the confirmation email that Google sent you. After Google receives the LOA, we begin the process of establishing your connections.
your Google Cloud resources
Complete the required configuration in Google Cloud. First, create a redundant set of VLAN attachments in your Virtual Private Cloud (VPC) network. Each VLAN attachment represents a logical connection between a region in your VPC network and your Azure resources. Then, for each VLAN attachment, use a Cloud Router to configure a Border Gateway Protocol (BGP) peering session.
- Configure your Azure resources
Configure your Azure resources. This step includes creating an ExpressRoute circuit, creating a private peering, and completing other tasks.
- Verify your connections
Follow the recommended steps to verify that your networks are connected.
You can also use Cross-Cloud Interconnect to connect to other cloud service providers.
