Enterprises typically buy MCNS and install it in a cloud provider‘s environment like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud. According to Lerner, those purchasing decisions are driven by the need for a certain networking feature that doesn’t natively exist in an organization’s cloud environments, like route encryption or improved troubleshooting capabilities. “Or, they buy it because they want the same consistent stack in multiple environments so they don’t have to have three different sets of networking stacks to deal with,” he added.
