This documentation will eventually be updated to reflect the rebranding.

When running in or across cloud environments (such as AWS, Azure, GCP, or PWS), PCC with PCF offers several advantages
over trying to run and manage your own standalone {geode-name} clusters. It handles many of the infrastructure-related,
operational concerns so that you need not do so.

By default, Spring Boot applications run as a `cluster_operator` role-based user in {pcf-name} when the application

One of the reasons why Spring Boot apps default to running as a `cluster_operator` is to allow configuration metadata to
be sent from the client to the server. Enabling configuration metadata to be sent from the client to the server is a
useful development-time feature and is as simple as annotating your main `@SpringBootApplication` class with

For example, when you declare the region where an application entity is persisted by using the `@Region` mapping
annotation and declare the `@EnableEntityDefinedRegions` annotation on the main `@SpringBootApplication`
class in conjunction with the `@EnableClusterConfiguration` annotation, not only does SBDG create the required
client region, but it also sends the configuration metadata for this region to the servers in the cluster to create
the matching, required server region, where the data for your application entity is managed.

Not all Spring Boot applications using PCC need to change the schema or even modify data. Rather, certain applications
may need only read access. Therefore, it is ideal to be able to configure your Spring Boot applications to run with
a different user at runtime other than the auto-configured `cluster_operator`, by default.
A prerequisite for running a Spring Boot application by using PCC with a specific user is to create a user with restricted
permissions by using {pcf-name} AppsManager while provisioning the PCC service instance to which the Spring Boot app
