Spring Boot makes the development of Spring-based applications easy. Spring Data makes it easy to connect to different data stores.

r, we looked at how Spring Data makes it easy to connect to different data stores through simple concepts such as repository. We also came to know how to use Spring Data in combination with Spring Data JPA to connect to an in-memory relational database and how to use Spring Data MongoDB to connect and save data to a Big Data store, such as MongoDB.

In the next chapter, we will shift our attention toward the cloud. We will learn about Spring Cloud and how it solves the problems of the Cloud.
