Cloud adapters simplify and accelerate integration between SaaS applications, and between on-premises applications and SaaS applications. These adapters provide lower costs of implementation and maintenance, ease of use, improved developer productivity and faster time-to-market for Saas application integrations. The cloud adapters are automatically included with Oracle SOA Suite Cloud Service.
If you use the cloud adapter pack, before you can use Fusion Middleware Control to deploy applications, you must add a managed server IP in to a non proxy host.
