I am seeing quite a few comments appearing regarding Cisco Overlay Transport Virtualisation recently so I figured it was worth commenting on.
One element of Cloud is being able to easily move workloads around, in and out. The harder this is the more difficult the adoption. If you have ever architected or even harder, implemented, a DR solution you know that re-addressing the networking for a pile of machines can be either difficult, "non-trivial" or just down right impossible. At the same time we see companies such as EMC and F5 working on doing VMotion across sites.
An outcome of this workload migration into the Cloud and long term VMotion across sites is the spreading of layer 2 networks across physical sites. [..]
