Enterprise Manager contains three built-in roles for the Database Cloud Service Portal, namely:

M_CLOUD_ADMINISTRATOR: Users with this role can set up and manage the cloud infrastructure. This role is responsible for deploying the cloud infrastructure (servers, zones, storage, and networks) and infrastructure cloud operations for performance and configuration management.

EM_SSA_ADMINISTRATOR: Users with this role can define quotas and constraints for the self service users and grant them access privileges. Users with this role also have provisioning and patching designer privileges that allow them to create and save deployment procedures, create and view patch plans, and support the plug-in lifecycle on the Management Agent.

EM_SSA_USER: Users with this role, by default, can only access the Self Service Portal. An administrator with the EM_SSA_ADMINISTRATOR role can provide additional privileges that allow users with the EM_SSA_USER role to access other features in Enterprise Manager.
