13.2. Large-Scale Redundant Setup

This diagram illustrates the network architecture of a large-scale CloudPlatform deployment.

• A layer-3 switching layer is at the core of the data center. A router redundancy protocol like VRRP

should be deployed. Typically high-end core switches also include firewall modules. Separate

firewall appliances may also be used if the layer-3 switch does not have integrated firewall

capabilities. The firewalls are configured in NAT mode. The firewalls provide the following functions:

• Forwards HTTP requests and API calls from the Internet to the Management Server. The

Management Server resides on the management network.

• When the cloud spans multiple zones, the firewalls should enable site-to-site VPN such that

servers in different zones can directly reach each other.

• A layer-2 access switch layer is established for each pod. Multiple switches can be stacked to

increase port count. In either case, redundant pairs of layer-2 switches should be deployed.
