Portal is the point-of-entry to the FlowGrid system. From the
Portal the several actors in the FlowGrid system can perform
their basic tasks.
- Users can subscribe to FlowGrid
and download the Client. End-users are able to subscribe/register
to the FlowGrid service. New subscribers are presented with
a Registration form which they need to fill and submit. Existing
users are able to modify/update their records, after logging
in to the system. On registration, end-users are presented
with the option of downloading the FlowGrid client. Furthermore,
end users are able to apply for a Certificate from the Certificate
Authority, to enable them to use the FlowGrid facilities.
- Resource providers. A Resource
Provider is able to access information on the systems/resources
that she has made available to the FlowGrid services. This
is a web-based interface displaying information on the Resource
Provider and the resources that have been made available.
Resources can be added to or withdrawn from the system by
the resource provider
- The administrator oversees
these tasks. The FlowGrid administrator has the authority
to add or remove Resource Providers from the FlowGrid service.
These actions are controlled by the Certificate Authority
or any other organisation that has the authority to manage
the Resource Providers accounts. After login-in, an administrator
has a view of all the resource providers that have joined
the FlowGrid service.
- The software required for
the management of subscribers, resources and resource-providers
can be accessed through the FlowGrid Manager Interface. Behind
the FlowGrid Manager Interface consists of Perl/CGI modules
running on an Apache Web-server, and performs all the portal
functions, including the management of information through
the MySQL database management system (DBMS). The flow of information
in the FlowGrid Portal is illustrated in the figure.
