Connectivity options
1. Connectivity options
Cloud Interconnect provides a fast connection to Google's network, Google offers two different cloud interconnects products, choose a product based on your situation and your needs. When you can physically connect to the Google network at a colocation facility, use Dedicated Interconnect. When you cannot connect to the Google network at a colocation facility, but can connect through a service provider, use Partner Interconnected. When you want to connect to other cloud providers directly, use Cross-Cloud Interconnect. Google Cloud also offers Cloud VPN, Cloud VPN can be useful when you have lower bandwidth needs, or when you must encrypt data in transit. In this module, you will learn more about the three types of cloud interconnect. Let's compare these connection options, all these options provide internal IP address access, between resources in your on premises network, and in your VPC network. The main differences are the connection capacity and the requirements, for using a service. The IPsec VPN tunnels, that cloud VPN offers, have a capacity of 1.5 gigabits per second, to 3 gigabits per second, per tunnel. The tunnels connect to a VPN device in your on premises network. The 1.5 gigabits per second capacity, applies to traffic that traverses the public internet, and the three gigabits per second capacity, applies to traffic that is traversing a direct peering link. If you want to scale this capacity, you can configure multiple tunnels. Dedicated interconnect has a capacity of 10 gigabits per second, or 100 gigabits per second, per link, and requires you to have a connection, in a Google supported colocation facility. You can have up to eight links to achieve multiples of 10 gigabits per second, or up to two links to achieve multiples of 200 gigabits per second, but 10 gigabits per second is the minimum capacity. Partner interconnect has a capacity of 50 megabits per second, to 50 gigabits per second, per connection, and requirements depend on the service provider. Dedicated Interconnect, and Partner Interconnect, do not encrypt data in transit. Secure data in transit at the application layer, using TL's for example. Cross-Cloud Interconnect enables you to establish high bandwidth dedicated connectivity between Google Cloud and another cloud service provider. Cross-Cloud Interconnect connections are available in two sizes,10 gigabits per second, or 100 gigabits per second.2. Let's practice!
