Apache Ignite provides interfaces for developing and deploying services to Ignite nodes where your data and service will collocate. In this chapter, we will build and deploy a Java service to an Ignite cluster. We will also build a data-oriented microservice and deploy it on an in-memory cluster.

We'll also examine the complex event processing (CEP) and event streaming (ES) concepts using Ignite.

The following topics will be covered:

• Service grid
• Ignite microservices
• Complex event processing
