SQL Azure Federation Architecture Solution

Federations is one of the most effective aspect of any architecture design, which basically provides de-centralization of operations, effectively providing parallelism, scalability, de-coupling and multi-tenancy. Cloud has become a dominant platform for any kind of architectures, and federations on the cloud for multi-tenant solutions are even more interesting and challenging. In Microsoft parlance, this would translate to SQL Azure Federations. A lot of reference material is already available on the same, so I would not go into explaining the same again.
