Exacc overview

Overview and scope of Customer 

Oracle’s Exadata Cloud@Customer (ExaCC) is an on premise cloud solution offered by Oracle for clients who want to venture into the Cloud technology with its elasticity and agility for hosting its databases but do not want to expose its data into the public cloud. 

ExaCC solution design involves the deployment of Oracle’s Exadata Platform in the customer’s data centers with appropriate networking components configured with sufficient controls for any interaction with the Oracle cloud interfaces.

In an ExaCC platform, the Exadata Appliance, which is hosted on a client’s data center, is configured with a control plane server and interfaces with Oracle cloud interface using a secure tunnel.  While Oracle manages the infrastructure components, the clients manage the virtual machines and database components.
