Reminds me of GFS. Though it is certainly interesting technology,
no one has come out with models that show it's performance
benchmarks exceeding the performance of local storage.
Does anyone know of large and mission critical databases that are
heavily used, implemented with GFS?
I think cloud computing may be interesting campus projects, but
hardly a serious solution to critical business requirements.
