Oracle Multi-VM Autonomous Database lands on Exadata systems

Oracle has extended the capabilities of its Exadata Cloud at Customer hardware service with a multi-VM autonomous database feature that has become generally available today.

Oracle Cloud at the customer enables organizations to use Oracle Cloud Infrastructure in an on-premises deployment.

The approach is similar to what other major cloud providers use, such as Amazon with its AWS Outposts Platform.

Autonomous and non-autonomous

the Exadata platform is Oracle’s on-premises hardware to run the Oracle database. Until now, Exadata was not running the standalone Oracle Database – which is a fully managed service – but rather the non-standalone version of the Oracle Database.

With the new Oracle Multi-VM Autonomous Database features for Exadata Cloud at Customer, organizations can now run both types of Oracle database (autonomous and non-autonomous) on the same physical infrastructure.

With this move, Oracle is now taking on-premises database automation to a new level by providing a complete self-service database cloud option, said Ron Westfall, analyst at Futurum Research.

Oracle Multi-VM Autonomous Database on Exadata Cloud at Customer provides cloud database functionality in customer data center deployments that can meet the needs of Oracle database users, Westfall said.

How the Multi-VM Autonomous Database Works

It is important to Oracle to allow its users to run multiple versions of Oracle Database.

Robert Greene, vice president of product management/strategy at Oracle, noted that many organizations have large database deployments that can run hundreds or even thousands of Oracle database instances.

With such large deployments, Greene said it can be difficult to move existing on-premises Oracle databases to the Oracle Autonomous Database. Meanwhile, many organizations will need to support and operate non-standalone Oracle database deployments for years to come, he added.

It was possible for organizations to run both types of Oracle databases before the release of the Multi-VM Autonomous Database for Exadata, but Greene said it would have been a bit more expensive if users were running both. types of databases on different hardware or cloud services.

“In the past, it took a fairly large second capital investment to make both of these non-standalone and standalone systems work,” Greene said. “Now they can do everything together. Thanks to virtualization, they can deploy multiple clusters of virtual machines on Exadata systems.”

Greene explained that the virtualization technology Oracle uses to enable the new feature is based on Kernel-based Virtual Machine (KVM) hypervisor clustering.

KVM is part of Oracle Linux, the base operating system run by the Exadata system. The multi-VM standalone database inside the Exadata hardware also uses Oracle Real Application Clusters and incorporates the RDMA over Converged Ethernet protocol which enables 100 Gbps network connectivity between virtual machines.

Multi-VM Autonomous Database support is a somewhat late decision for Oracle.

Greene acknowledged that this is a feature that Oracle customers have long requested. But it was a difficult and complex effort to deliver the service in a way that Oracle could guarantee service-level agreements in mixed-mode environments, he said.

“It was just an engineering effort for us to do it,” Green said. “We’ve been working on it for quite a long time, and now it’s ready.”

Oracle Multi-VM Autonomous Database enables the organization to operate both stand-alone and user-managed versions of the Oracle database on the same physical hardware.
