Oracle CEO Larry Ellison is putting his old grudges aside as part of an effort to loosen Amazon’s monopolistic grip on infrastructure-as-a-service and establish a foothold in the public cloud market. Recognizing that it needs all the help it can get, the database giant is making new friends and even warming up to arch-nemesis Salesforce.

The company on Thursday pulled the curtain back on Oracle Cloud Adapter for Salesforce.com, the newest addition to its portfolio of more than 300 connectors for migrating data to and from third party solutions. The integration is the first of its kind to unify on-premise Oracle software with a hosted service.

“Until now, organizations have relied on a mix of integration tools, each focusing on either cloud or on-premise applications,” noted Demed L’Her, the vice president of product management at Oracle. “With Oracle Cloud Adapters, Oracle has extended our commitment to simplifying and securing key applications by unifying the integration experience between cloud and on-premises applications.

The adapter is as an extension of the firm’s SOA Suite, which is pegged as the industry’s “most complete and unified application integration solution.” It uses Oracle’s Credential Store Framework, a set of APIs for managing security data, to prevent confidential credentials from being exchanged over the network, and includes a standardized wizard that speeds up the setup process. The company says that the connector can reduce integration time by half while eliminating the overhead associated with manually implementing and then maintaining the same processes.

“Oracle will continue to release additional out-of-the-box adapters with Oracle SOA Suite to help customers better connect to cloud applications,” L’Her said. The company is also planning to offer technology from Responsys, the software-as-a-service vendor it acquired last month for $1.5 billion, as part of the Oracle Customer Experience Cloud.
