In this chapter, we will start by learning the theoretical basis of OpenShift storage configuration. Later, we will show you how to deploy a database in the cloud and configure your cloud applications to use it.
In the last section of the preceding chapter, we deployed the simple version of CatalogService in the cloud, using OpenShift. We also got an initial feeling for the web console and OpenShift cli. Now, it is time to go further. We will reconfigure our application to use the database.
Before doing that, we will cover OpenShift persistence storage concepts.
