Introduction

• Globus is
• A community of users and developers
• The software itself
• service implementation
• new Web services
• security infrastructure
• client APIs and command line programs
• documents
• The infrastructure that supports this community

Motivation and Concepts

• To enable applications that federate distributed
  resources (computers, storages, data, services,
  networks and sensors)
• The demand of VO in science gt Commercial
  applications
• Extensive use of Web services mechanisms
• A set of Grid infrastructure services

• How Do I Access and Move Data?
• several GT4 components implement useful
  mechanisms that can be used individually and in
  conjunction with other components to develop
  interesting solutions.
• GridFTP
• provides libraries and tools for reliable,
  secure, high-performance memory-to-memory and
  disk-to-disk data movement.
• RFT
• privides for the reliable management of multiple
  GridFTP transfers.
