In Chapter 1, Getting Familiar with Apache Ignite, we learned about various features and the architecture of Apache Ignite; this chapter covers the bare bones of Apache Ignite. We'll look at Apache Ignite clustering, caching topology, and caching strategies. Clustering, caching topology, and caching strategies solve different enterprise architecture problems. In this chapter, we are going to cover the following topics:

• CAP theorem and Apache Ignite
• Clustering architecture
• Caching topology
• Clustering strategy
