What does Grid players require?

They need tools and technologies that help them in value expression, value translation, and value enforcement.

Grid Service Consumers (GSCs): How do I express QoS requirements ? How do I trade between timeframe & cost ? How do I map jobs to resources to meet my QoS needs? How do I manage Grid dynamics and get my work done? …

Grid Service Providers (GSPs) How do I decide service pricing models ? How do I specify them ? How do I translate them into resource allocations ? How do I enforce them ? How do I advertise & attract consumers ? How do I do accounting and handle payments? …

10

Solution 1: Service Oriented Architecture (SOA)

A SOA is a contractual architecture for offering and consuming software as services.

There are four entities that make up an SOA service provider, service registry, and service consumer (also known as service requestor).

The functions or tasks that the service provider offers, along with other functional and technical information required for consumption, are defined in

the service definition or contract.

Summary and Conclusion

Grids have emerged as enabler for Cyberinfrastructure that powers e-Science and e-Business applications.

Delivering ICT services as computing utilities. Australia is actively developing Grid technologies and

applications Recently Australian Govt. is pushing Grids heavily under

e-Research banner. Melbourne is leading a number of Grid projects nationally. SOA + Market-based Grid Management = Utility Grids Grids allow users to dynamically lease Grid services at

runtime based on their quality, cost, availability, and users QoS requirements.

Grids offer enormous opportunities for realizing e-Science and e-Business at global level.
