Oracle Exadata Cloud@Customer is the simplest way to move an organization’s business-critical Oracle Database workloads to the cloud. It simultaneously runs Oracle Exadata Database Service and the fully managed Oracle Autonomous Database Service inside customers’ data centers and behind their firewalls to help meet strict data residency and security requirements. Built using the latest Exadata technology, Exadata Cloud@Customer delivers the highest cloud database performance, scale, and availability, enabling organizations to run all types of database workloads faster and with up to 69% less management, according to IDC’s Business Value Analysis. Now Oracle makes it easier and less expensive for customers to adopt Autonomous Database by running it on VMs in Exadata Cloud@Custom.
