Oracle Cloud Application Foundation

 

Oracle Cloud Application Foundation provides services between the clients and databases for an organization.   These services are provided through the implementation of Application Services and Cache Services.    Application Services are provide through the use of WebLogic Server which handle all deployment of Application via web services, database connections, security, and all other common application required needs.   The Application Services allows the organization to focus on the core requirements of their application and deliver quicker business value.  Cache Services are provided through the use of Oracle Coherence which allow for ready access to common data resources.   Cache data services allow for quicker access to common data used by multiple applications or multiple times by the same application.   Additionally, reduces the database resource requirements by reducing the frequency and intensity of data access.  Both WebLogic and Coherence support clustering to allow an organization scalability as their processing needs grow.   Oracle WebLogic and Coherence are the base of Oracle Cloud Services and all other oracle services such as Finance, SOA, Identity Management, System Management, etc are built on top of them.
