In November 2011, Oracle introduced Oracle Solaris 11—the first cloud OS. In April 2014, Oracle introduced Oracle Solaris 11.2, with updated cloud features. A cloud OS must do more than update features, however, and Oracle Solaris certainly does more, with new cloud features and technologies that will continue to open the cloud to high-performance mission-critical applications.

Ongoing Evolution

Oracle Solaris 11.2 feature updates deliver better performance for Oracle environments running the cloud OS, including kernel mode acceleration, which delivers performance acceleration for Oracle Real Application Clusters; memory prediction technology, which enables lower memory utilization; and a new shared memory model and other Oracle Database co–engineered enhancements.

Perhaps one of the most overlooked ongoing features of all recent Oracle Solaris releases has been the guarantee. The Oracle Solaris Guarantee Program ensures that even as new Oracle Solaris releases support new features, binary applications and source code developed for earlier releases of Oracle Solaris will continue to run on newer releases.

Open Revolution

Oracle Solaris 11.2 includes built-in, efficient enterprise cloud virtualization. Oracle Solaris Zones, for example, have been enhanced in the new release to include support for fully independent and isolated environments, called kernel zones. Also new in the cloud OS, application-driven software-defined networking support, from application to storage, helps to ensure that application service-level agreements are maintained within data center and cloud environments. One new feature of the Oracle Solaris 11.2 cloud OS, however, has received the most attention: a complete OpenStack distribution.

OpenStack is an open source cloud project, and the OpenStack distribution in Oracle Solaris is a foundation for building an Oracle Solaris–based cloud. OpenStack in Oracle Solaris 11.2 provides a central location for managing compute, networking, and storage resources. With OpenStack, Oracle VM templates, and the new unified archives capability, organizations can deploy a single-system, multi-virtual-machine OpenStack environment in a matter of minutes.

New features mean new choices. For virtualization, Oracle Solaris 11.2 supports multiple virtualization technologies, including Oracle Solaris Zones and Oracle VM Server for SPARC. In addition to the option to build Oracle Solaris–based clouds with OpenStack, Oracle Solaris 11.2 offers the choice to build clouds based on the Oracle Optimized Solution for Enterprise Cloud Infrastructure.
