This chapter explained the service grid concept and microservice deployment on Apache Ignite. We explored the core service grid APIs, the Service and IgniteServices interfaces, along with how a service can be defined, deployed, and cancelled. We also covered the importance of deploying a microservice on a service grid cluster and how the framework takes care of service availability, scalability, and inter-service communication.

This chapter also covered complex event processing, event data streaming APIs, and continuous queries. Ignite supports almost all major data streamers, such as JMS, Kafka, and Camel.

The Chapter 6, Sharpening Ignite Skills, will cover the following topics: Ignite data persistence with RDBMS and NoSQL data stores, transactional CRUD operations, locks, off-heap and native data stores, distributed data structures, including queues, sets, and ID generators, and Ignite's RESTful API.
