The Globus Consortium has announced the release of the Globus Toolkit Version 4.0 (GT4) as a stable, enterprise ready set of services and software libraries incorporating the latest web services standards, with new security and authorization features.
The Globus Consortium, announced January 24, 2005, "is comprised of global computing leaders who support the Globus Toolkit. HP, IBM, Intel and Sun Microsystems are the Globus Consortium's Founding members; supporting entities also include Nortel Networks, Univa, and others. According to Ian Foster, Board Member with the Globus Consortium, "The leading enterprise Grid vendors and standards bodies are standing behind GT4 as the preferred open source software for enterprise Grids. For nearly a decade, a global community of Grid developers have contributed to Globus Toolkit code."
The Globus Toolkit is "an open source software toolkit used for building enterprise-level Grid systems and applications. Freely available in open source format on the Web, the Globus Toolkit provides applications for security, information infrastructure, resource management, data management, communication, fault detection, portability, and more.
Grid computing, as defined by the Globus Toolkit implementation, refers to "an information technology infrastructure that enables the integrated, collaborative use of computers, networks, databases, and scientific instruments owned and managed by many different organizations in many different locations. Grid applications often involve large amounts of data and/or computing and often require secure resource sharing across organizational boundaries."
The Globus Toolkit Version 4 (GT4) supports "interoperability, flexibility and the freedom to choose the best vendor products and equipment" to implement enterprise Grid solutions. The Globus Consortium announcement identifies four new areas of support for interoperable computing solutions: (1) GT4 complies with the latest Web Services Interoperability Organization (WS-I) web services standards, which provides maximum interoperability between different environments.; (2) GT4 includes initial support for important authorization standards, including Security Markup Language (SAML) and Extensible Access Control Markup Language (XACML); these provide business with a foundation for building a secure web-services enabled Grid infrastructure; (3) GT4 implements the Web Services Resource Framework (WS-RF) and Web Services Notification (WS-N) specifications, which are emerging standards in OASIS backed by major vendors for web services enablement of Grid and resource management systems; (4) GT4 features sophisticated authorization and security capabilities so as to make the toolkit 'enterprise ready' from a security perspective."
According to a May 2005 'Globus Consortium Update', GT4 "has been implemented with a method of execution management (GRAM) that is centered on web services. The Consortium will sponsor the creation of documents that capture the GT4 WS-GRAM interfaces, semantics, and abstractions in a form that is suitable for input to standards discussions. This will include a roadmap that describes how the functionality embodied in GT4 WS-GRAM can be standardized in stages, and how other standards efforts such as WSDM, WS-Agreement, and WS-CIM might be brought to bear on execution management standards at various stages. Working groups will either be engaged with or formed in the appropriate standards bodies, support from other organizations will be recruited, and there will be an on-going effort to participate and drive discussion within these groups."
"The open source Globus Toolkit is a fundamental enabling technology for the 'Grid,' letting people share computing power, databases, and other tools securely online across corporate, institutional, and geographic boundaries without sacrificing local autonomy. The toolkit includes software services and libraries for resource monitoring, discovery, and management, plus security and file management. In addition to being a central part of science and engineering projects that total nearly a half-billion dollars internationally, the Globus Toolkit is a substrate on which leading IT companies are building significant commercial Grid products.
The toolkit includes software for security, information infrastructure, resource management, data management, communication, fault detection, and portability. It is packaged as a set of components that can be used either independently or together to develop applications. Every organization has unique modes of operation, and collaboration between multiple organizations is hindered by incompatibility of resources such as data archives, computers, and networks. The Globus Toolkit was conceived to remove obstacles that prevent seamless collaboration. Its core services, interfaces and protocols allow users to access remote resources as if they were located within their own machine room while simultaneously preserving local control over who can use resources and when.
The Globus Toolkit has grown through an open-source strategy similar to the Linux operating system's, and distinct from proprietary attempts at resource-sharing software. This encourages broader, more rapid adoption and leads to greater technical innovation, as the open-source community provides continual enhancements to the product..." [adapted from About]

The Globus Consortium today [2005-05-02] announced the release of Globus Toolkit, version 4.0 (GT4), developed by the Globus Alliance. The Globus Toolkit is an open standards building block for enterprise-level Grid implementations.
GT4 is the most stable, "enterprise ready" version of the Globus Toolkit ever — incorporating the latest web services standards, new security and authorization features, and the collaborative efforts of a global community of open source Grid developers. GT4 can be downloaded at:
"Interoperability, flexibility and the freedom to choose the best vendor products and equipment is what enterprise Grid is all about," said Ian Foster, Board Member with the Globus Consortium. "The leading enterprise Grid vendors and standards bodies are standing behind GT4 as the preferred open source software for enterprise Grids. By building Grids with the Globus Toolkit, and by working with vendors who support the Globus Toolkit — organizations can best position themselves to exploit the full potential of enterprise Grid."
For nearly a decade, a global community of Grid developers have contributed to Globus Toolkit code, and this latest GT4 release includes all of the necessary tools for building an enterprise Grid. Key additions to GT4 include:
GT4 complies with the latest Web Services Interoperability Organization (WS-I) web services standards, which provides maximum interoperability between different environments.
GT4 includes initial support for important authorization standards, including Security Markup Language (SAML) and Extensible Access Control Markup Language (XACML). These provide business with a foundation for building a secure web-services enabled Grid infrastructure.
GT4 implements the Web Services Resource Framework (WS-RF) and Web Services Notification (WS-N) specifications, which are emerging standards in OASIS backed by major vendors for web services enablement of Grid and resource management systems.
GT4 features sophisticated authorization and security capabilities. Globus has always been diligent in Grid security, and GT4 is also "enterprise ready" from a security perspective.
"For nearly a decade, major vendors and standards bodies — including the Global Grid Forum (GGF) — have contributed to the open source Globus Toolkit," said Mark Linesch, Chair of the GGF. "The Globus Toolkit has seen terrific success in research, academic and commercial high-performance computing environments. By continuing to align with the latest grid and web services standards, GT4 is poised for broader adoption — particularly in enterprise markets where efficient resource sharing and more effective data integration are becoming increasingly critical."
North Carolina-based MCNC, which tests and deploys advanced networking solutions on its North Carolina Research and Education Network (NCREN) in partnership with North Carolina universities and state government, recently performed successful "testbed" work on GT4 — with systems set up across the OC48 NCREN backbone. Vendor participants included: Cisco, Gridwise Technologies, IBM, Network Appliance, Red Hat and Sun.
"GT4 brings in all the standards and interfaces," said Wolfgang Gentzsch, the Managing Director at MCNC who oversaw the GT4 testbed efforts. "GT4 is much more flexible — it brings in the ability to easily enhance Grid towards additional services, like accounting and billing, metering and measuring. Now that a larger part of GT4 is based on web services — it is much easier to interface and communicate with other tools which are based on the same web services standards. As a result, more and more commercial tools will be compliant in the near future with Grid services."
Also standing behind the Globus Toolkit are the Globus Consortium Members — HP, IBM, Intel, Nortel, Sun and Univa — all of which have enterprise Grid products and services built on or around the Globus Toolkit. For example, IBM has offered its IBM Grid Toolbox based on the Globus Toolkit, and later this fall will announce a version based on GT4. And Grid Engine, the open source project sponsored by Sun, has been integrated into GT4 for a project at Imperial College in London. MCNC and Gridwise Technologies have also contributed to this effort.
"Globus Toolkit 4.0 allows enterprise users to bring standardized web services into a Grid environment, further simplifying the automated allocation of resources available on a Grid," said Greg Astfalk, Chief Scientist, Office of Corporate Strategy and Technology at HP. "HP sees Grid as a powerful way to virtualize and manage resources, enabling companies to respond to changing business needs and realize HP's vision of becoming Adaptive Enterprises."
"Standards are key to accelerating adoption of Grid Computing in the commercial marketplace," said Ken King, IBM's Vice President of Grid Computing. "A key driver of grid standards is the successful implementation and acceptance of Globus with enterprise customers. The new Globus Toolkit 4.0 adds more robust web services capabilities, enhanced security and powerful authorization features that we believe will be very compelling to our customers as they look at Grid as a way to simplify their infrastructure."
"Sun is actively engaged in bringing the productivity gains of grid computing into the enterprise," said Sohrab Modi, vice president, N1 Grid Systems, Sun Microsystems. "As a major supporter of open standards and open source software, Sun is pleased to see the arrival of Globus Toolkit 4 as another key tool toward achieving widespread use of grid technologies in the enterprise."
"Enterprises are increasingly challenged by constricting IT budgets, yet frustrated with proprietary, inflexible systems that remain under-utilized," said Steve Tuecke, CEO of Univa Corporation, a provider of commercial software, technical support and professional services for the Globus Toolkit. "Since the previous release of the Globus Toolkit, we have witnessed the emergence of many Web Services standards that are relevant for Grid infrastructure. Expanded support for these standards throughout GT4 enables enterprises to more easily integrate existing IT systems with Globus in order to optimize the use of existing computing, storage and networking resources."
