3. 3 Overview What is a portal? How does it use certificates?

4. 4 What is a Portal? 1. In simple terms, –A Portal generates framework, and –Portlets fill in the contents 2. This is: http://portal.ngs.ac.uk/http://portal.ngs.ac.uk/

5. 5 NGS portal Grids are about people collaborating, so give tools for this! Need to run jobs, access data, … from different machines and places – but do NOT want to –carry certificate everywhere! – install GT2 before you can use any commands or resources Using the command line tools is tedious; simple tasks can be achieved easily in a portal Also, easy interface to the Information Service

6. 6 Certificates, MyProxy Rather than storing your Grid credentials on each machine you use to access the Grid, you can store them in a MyProxy repository and retrieve a proxy credential from the MyProxy repository when needed. MyProxy is part of VDT A MyProxy server is run for the NGS portal Before you can use the NGS portal, you must upload a proxy certificate: Java Web Start tool http://tiber.dl.ac.uk:8080/myproxy
