Introduction Globus is • A community of users and developers who collaborate on the use and development of open source software, and associated documentation, for distributed computing, virtual organizations, resource federation • The software itself – Globus Toolkit: a set of libraries and programs that address common problems that occur when building system services and applications

  3. Introduction(cont’d) • The infrastructure that supports this community code repositories, email lists, and problem tracking systems. All are accessible at dev.globus.org • Developed in the late 1990’s

  4. Globus Toolkit Version 4 • Provides a variety of components and capabilities, including: • A set of service implementations that address resource management, data movement, and service discovery • Tools for building new Web Services • A powerful standards-based security infrastructure, for authentication and authorization • Detailed documentation on these various components, their interfaces, and how they can be used to build applications

  5. Globus Architecture • A set of service implementations implement useful infrastructure services • Three containers can be used to host user-developed services written in Java, Python, and C • A set of client libraries allow client programs in Java, Python, and C to invoke operations on both Globus Toolkit and user-developed services
