When you first deploy your Rancher cluster, networking likely isn’t the first thing you think about and often the default settings are used. However, given that microservices require a network to function, it’s important to choose the right networking options before you run into scale issues and other roadblocks related to the network.

Rancher comes packaged with powerful networking and network security software called Project Calico. With Calico, you have many networking options available at your fingertips, and selecting the right options can help you build massive scale into your Rancher cluster.

In this training session, you will learn:

• What networking options are available in Rancher
• The pros and cons of each networking option, and how to choose the right options for your cluster
• How to secure your Rancher network using Calico
• An introduction to Calico Enterprise for network troubleshooting, egress access controls, and advanced security

Calico is free and available with Rancher. If Calico Enterprise looks interesting, a free trial is available pre-installed on Rancher for you to try on your own.
