In this chapter, we covered the hierarchical and failover configurations of Salt, using syndication and multiple masters. We also talked about load testing and offloading resources from the master to other servers. We even talked about managing the master using the wheel system.
There are plenty of ways to help your Salt infrastructure scale to meet the demands of thousands of servers. But once they're up-and-running, how do you keep an eye on them? Next up, we'll discuss how we can use Salt to help monitor our systems.
