2. Statement on Sustainable Grids In order for grid infrastructure to be sustainable… –A tangible business plan for sustainability So, what would the business plan target? –Plan1: Competitive advantage and benefits to a small, high-paying users (classic supercomputer model), or –Plan2: A “must-be” part of wide-ranging users’ everyday workcycle (the Internet) OK, which one do we have right now? –Fact: production grid user base is a few thousand users –Fact: not that different from traditional supercomputer user base –So do we continue with plan 1? Claim: Grids are not sustainable with plan1: –Cannot bring much more value beyond traditional supercomputing Machines and storage are getting larger MILLIONS of users, their identity and security model available ubiquitously Alright, but what would it take to pursue Plan 2? –From infrastructure-centric view to user-centric view => from tending hardware/software to virtual organization support as premium technical challenge –Base services must be ubiquitously available => scaliability and stability –Resources must be ubiquitously available and abundunt => scalability –New services must be easy to build, deployed, serviced, and sustained –The Internet datacenter model --- services must be easily hosted, instead of being administered by the VOs themselves –Wide industry adoption => standards compliance
