The Microsoft Perspective

• Strong design skills
• Good Microsoft product knowledge
• Microsoft values EPCC input to Globus and GGF on
  best practices for using Web services in Grid
  Computing
• Work is important to show that pure Web services
  are a platform of choice for Grid computing
• EPCC have handled the project very professionally
  and have kept Microsoft informed of their
  progress
• They have taken Microsoft feedback into account

Future Plans

• Ongoing support for users
• Dissemination
• Microsoft Academic Days, Dublin, April 2004
• WWW site continuing to make available software
  and training materials
• Exploitation
• Contribute to WSRF debate
• Use of Web Services programming model
• Providing WS-Resources using files or Microsoft
  SQL Server
• Possibility of related projects in
