Oracle and Open Source

Choice, Flexibility, and Lower Cost with Oracle and Open Source

Oracle is committed to offering choice, flexibility, and lower cost of computing for end users. By investing significant resources in developing, testing, optimizing, and supporting open source technologies such as MySQL, GlassFish, Java, Linux, PHP, Apache, Eclipse, Berkeley DB, NetBeans, VirtualBox, and Xen, Oracle is clearly embracing and offering leading open source solutions as a viable choice for development and deployment.

We cannot stress the importance of using open standards enough, whether in the context of open source or non-open source software. Today, many customers are using Oracle together with open source technologies in mission-critical environments and are reaping the benefits of lower costs, easier manageability, higher availability, and reliability along with performance and scalability advantages.
