Pigs and lipsticks
A cloud that relies on shared storage it's not Cloud.
1.000 nodes is a respectable figure (for not-CSPs), however I would like to see the price of the supporting infrastructure to reach that.
Cloud is synonim of near-linear scalability at low price (the latter trending to linearly decrease), I don't see this happening on shared storage architectures.
Heck, even VMWare admits they are looking for alternatives as distributed storage.
Nimbula, Eucalyptus and (on the application side) Hadoop: those are examples, to my knowledge, of scalable "shared-nothing" architectures for the Cloud, moreover, they all implement some sort of data/process vicinity.
Rebranding massive deployment tools as Cloud architectures seems to be the trend of the last months...
Where is a "fake cloud" icon?
