Google Cloud Interconnect provides direct and high-throughput connectivity between your on-premises network and Google Cloud. There are two types of Interconnect options: Dedicated Interconnect and Partner Interconnect.

Dedicated Interconnect:

Dedicated Interconnect allows you to establish a private, direct connection between your on-premises network and Google Cloud. This connection provides a dedicated and reliable link with a specified bandwidth.

Features:

1. Private Connection:

   • Dedicated Interconnect provides a private connection that bypasses the public internet, offering increased security and reliability.

2. Redundancy:

   • For mission-critical workloads, you can set up redundant connections to ensure high availability.

3. Service Level Agreement (SLA):

   • Google Cloud provides an SLA for Dedicated Interconnect, guaranteeing a certain level of uptime and reliability.

4. Scalable Bandwidth:

   • You can choose the bandwidth that suits your requirements, ranging from 50 Mbps to 100 Gbps.

5. Global Reach:

   • Dedicated Interconnect is available in various Google Cloud regions, allowing you to connect to resources globally.

Configuration Example:

Here's a basic example of setting up Dedicated Interconnect:

1. Ordering a Dedicated Interconnect:

   • Contact a Google Cloud Interconnect partner or use the Google Cloud Console to order a Dedicated Interconnect connection.

2. Physical Connection Setup:

   • Work with the interconnect partner to set up the physical connection between your on-premises network and Google Cloud.

3. Create a VLAN Attachment:

   • In the Google Cloud Console, create a VLAN attachment associated with your Dedicated Interconnect connection.

4. Create a Cloud Router:

   • Create a Cloud Router in Google Cloud to establish dynamic routing between your on-premises network and Google Cloud.

5. Configure Routing:

   • Configure the routing settings on both sides to ensure proper communication between your on-premises network and Google Cloud.

Partner Interconnect:

Partner Interconnect allows you to connect to Google Cloud using a supported service provider. The service provider establishes and manages the connection between your network and Google Cloud.

Features:

1. Service Provider Options:

   • Partner Interconnect is available through various service providers, allowing you to choose a partner that fits your requirements.

2. Flexible Bandwidth:

   • Similar to Dedicated Interconnect, Partner Interconnect provides flexible bandwidth options based on your needs.

3. Simplified Connectivity:

   • The service provider manages the connectivity, making it easier to establish and maintain the connection.

4. Global Reach:

   • Partner Interconnect is available in multiple regions globally through various service providers.

Configuration Example:

Here's a basic example of setting up Partner Interconnect:

1. Selecting a Service Provider:

   • Choose a service provider that offers Partner Interconnect and engage with them to set up the connection.

2. Ordering the Connection:

   • Work with the service provider to order the Partner Interconnect connection.

3. Google Cloud Configuration:

   • In the Google Cloud Console, create a VLAN attachment associated with your Partner Interconnect connection.

4. Service Provider Configuration:

   • The service provider configures the physical connection and establishes the link between your on-premises network and Google Cloud.

5. Create a Cloud Router:

   • Create a Cloud Router in Google Cloud to enable dynamic routing between your on-premises network and Google Cloud.

Always refer to the official documentation for the most up-to-date and detailed information on configuring Google Cloud Interconnect. The specific steps and configurations may vary based on your network topology, service provider, and other factors.
