Peering

1. Peering

Let's talk about the Cloud Peering services, which are Direct Peering and Carrier Peering. These services are useful when you require access to Google and Google Cloud properties. Google allows you to establish a direct peering connection between your business network and Google's. With this connection, you will be able to exchange Internet traffic between your network and Google's at one of the Google's broad-reaching edge network locations. Direct Peering with Google is done by exchanging BGP routes between Google and the peering entity. After a Direct Peering connection is in place, you can use it to reach all of Google services, including the full suite of Google Cloud products. Unlike Dedicated Interconnect, Direct Peering does not have an SLA. In order to use Direct Peering, you need to satisfy the peering requirements. Refer to the link in the Course Resources for details. Google Cloud's Edge Points of Presence, or PoPs, are where Google's network connects to the rest of the Internet via peering. PoPs are present on over 90 Internet exchanges and at over 100 interconnection facilities around the world. For more information about these exchange points and facilities, I recommend looking at Google's PeeringDB entries links provided in the Course Resources. If you look at this map and say, "Hey, I am nowhere near one of those locations," you will want to consider Carrier Peering. If you require access to Google public infrastructure and cannot satisfy Goggle's peering requirements, you can connect via a Carrier Peering partner. Work directly with your service provider to get the connection you need and to understand the partner's requirements. For a full list of available service providers, refer to the documentation link in the Course Resources. Now, just like Direct Peering, Carrier Peering does not have an SLA. Let me compare the peering options that we just discussed. All of these options provide public IP address access to all of Google's services. The main differences are capacity and the requirements for using a service. Direct Peering has a capacity of 10 Gbps per link and requires you to have a connection in a Google Cloud Edge Point of Presence. And Carrier Peering's capacity and requirements vary depending on the service provider that you work with.
