OpenDS is an open source community project building a free and comprehensive next generation directory service. OpenDS is designed to address large deployments, to provide high performance, to be highly extensible, and to be easy to deploy, manage and monitor. Initial development of OpenDS was done by Sun Microsystems, but is now available under an open source license.

Open ESB is an open-source project and community building the first fully open-source Enterprise Service Bus implementation based on the Java Business Integration specification and reference implementation. A rich set of components that plug into the platform are also being built including BPEL, XSLT, Event Processing, and Data Integration Service Engines, and HTTP, JDBC, FTP, SMTP, RSS, XMPP, and CORBA Binding Components. Open ESB is contributed to by Sun and community members and leverages the GlassFish and NetBeans community as well.

As the heart of the Java platform, Java SE is the execution engine and core development technology that enables the Java technology's "write once, run anywhere" promise. By open sourcing the Java Development Kit (JDK), Sun's implementation of Java SE, Sun hopes to make the Java platform a new foundation of innovation and enhance its value as the ubiquitous, essential infrastructure of the Internet experience.

OpenCDS is based on the source code of the Sun Java System Content Delivery Server (CDS), released by Sun under the Common Development and Distribution License (CDDL). The project is creating a mobile content delivery and management platform that enables mobile operators to launch and sustain content services.

The Open Media Commons is a community site for projects to develop unencumbered solutions for digital media. Current projects include Project DReaM, an open source, royalty-free and open standard Digital Rights Management (DRM) solution which will be independent of transport format. Other open source community projects are developing royalty-free codecs technology and streaming media services.

Open MPI is an open source implementation of MPI (Messaging Passing Interface) standard, a software library that is widely used in the creation of parallel, distributed high performance computing (HPC) applications. Sun is an active, contributing member of the Open MPI community, with its entire MPI engineering team working collaboratively to produce a high-quality, optimized, multi- platform implementation of MPI.

Open HA (High Availability) Cluster is the open-source code base of Solaris Cluster, a high availability clustering solution. Open HA Cluster includes over 2 million lines of code, integration with many key applications, globalization functionality, an automated test environment and documentation.

The OpenPrinting PAPI project is an open source implementation of the FSG OpenPrinting Open Standard Print API (PAPI). The project provides a set of specifications and implementations of software focused on creating standardized, scalable printing components for Solaris, GNU/Linux, or any other system with a set of POSIX interfaces. Sun has been involved in this project from the beginning. We continue to be a involved in the standards group that specified the interfaces and initiated and contributed much of the implementation of the standard in the SourceForge project.

Project Open Provisioning ToolKit (OpenPTK) is as an open source User Provisioning Toolkit exposing API's, Web Services, HTML Taglibs, JSR-168 Portlets with user self-service and administration examples. The architecture supports several pluggable back-end services including Sun's Identity Manager, Sun's Access Manager and LDAPv3.

The OpenOffice.org project was founded when Sun contributed several million lines of source code in 2000. Sun Microsystems remains still the main contributor of code.

The OpenSPARC project is making the hardware source code of the recently announced UltraSPARC T1 processor available under an Open Source license.

OpenSSO is an open source access management software distribution that provides the means to build authentication, authorization, and session management for Java and web applications and services. OpenSSO is maintained by a community of developers working closely with Sun engineers to promote the evaluation, use, and innovation of identity and access management technology.

Sun open sourced over 10 million lines of code in 2005 with the OpenSolaris project. Sun continues to sponsor the project by employing hundreds of software engineers who work on OpenSolaris, and by hosting the community site.

OpenxVM is a community hub for a number of related open source projects that related to xVM, the intersection of virtualization and management. OpenxVM projects are together creating the next generation of data center infrastructure.

PostgreSQL is an high-performance object-relational database system, based on 20 years of development and sustained by a worldwide community of developers and companies. Sun sponsors PostgreSQL developers and provides test equipment for the project. Solaris users adopt PostgreSQL as an alternative to proprietary databases capable of high-volume OLTP workloads.

Sun actively participates in the Apache Roller and currently devotes three engineers to the project, who help to plan releases, write the code and grow the Roller community. We sponsor Roller development to support the requirements of our internal and external blog sites, to advance content syndication and web publishing technologies (RSS and Atom) and to provide a great blog server for the Java community.

VirtualBox is a family of open source, powerful, feature rich x86 virtualization products for server, desktop and embedded us.
