Understanding cloud network connectivity use cases

Enterprises at this time have a really broad mixture of networks — from SD-WANs, devoted WANs reminiscent of MPLS, cloud interconnects, to VPNs. On the similar time, they’re transferring these WANs to the cloud to make the most of quicker turn-up, decrease value, and elevated function velocity. As workloads migrate to the cloud and multi-cloud environments, we imagine that it’s vital to simplify enterprises’ networking mannequin.

Every main cloud supplier makes use of distinct abstraction fashions to configure networks or connections between your sources. Some use gateways, some use connections or hyperlinks. Community Connectivity Heart, launched final yr, offers a easy administration resolution in your community connection, and is now Usually Out there. 

On this put up, we define the everyday connectivity use circumstances for purchasers that can assist you choose and arrange the perfect connectivity choice in your atmosphere.

Understanding cloud community connectivity

Cloud networking refers back to the capacity to attach two sources collectively inside a cloud, throughout clouds and with on-premises information facilities. A cloud supplier wants to offer three principal varieties of connectivity:

1. Web site-to-cloud – Between on-premises gear and cloud sources
2. Web site-to-site – To attach on-premises sources collectively
3. VPC-to-VPC – Connectivity between cloud sources

Let’s check out each. 

Web site-to-cloud connectivity

Web site-to-cloud connectivity historically is completed by way of a cloud interconnect or a cloud VPN. The automated change of routes between on-premises and a number of VPCs might be achieved utilizing a transit VPC. 

A more recent strategy is so as to add cloud suppliers into an SD-WAN mesh utilizing a router digital equipment in Google Cloud. Community Connectivity Heart brings the capability to synchronize the equipment routes dynamically by way of BGP to Cloud Router and therefore their VPCs. It allows connectivity between on-premises information facilities and department workplaces and their cloud workloads by way of SD-WAN-enabled connectivity. This functionality is out there globally throughout all 29+ Google Cloud areas. A number of of our companions additionally help this functionality of their router home equipment.
