Apache Ignite can automatically detect when a new node is added to the cluster, and similarly can detect when a node is stopped or crashed, transparently redistributing the data. This enables you to scale your system as you add more nodes. The coolest feature of this sophisticated clustering is that it can connect a private cloud's Ignite node to a public cloud's domain cluster, such as AWS. We will look at clustering in detail in Chapter 2, Understanding the Topologies and Caching Strategies.
