  1. There is alot of thrashing in this space and it is hard to determine which Cloud

    to goto as everyone is doing something a little different – its hard to compare

    Cloud 2 Cloud. A similar diagnosis is by David Chappell:
    “If I ruled the world”, says David Chappell, “I would make the phrase ‘private

    cloud’ illegal”. In conversation with David Gristwood, David Chappell, during his

    recent world tour, discusses the Cloud, its importance and role in the partner

    ecosystem, and cloud players, such as Google, Amazon, Salesforce.com, VMware and

    more. You can see his Cloud2Cloud comparison in brief here:

    A more recent talk with David Chappell on this topic where he covers others issues

    such as:
    – IaaS vs PaaS
    – Private vs Public Cloud
    – Applications that are not a great fit for the Cloud and those which are.
    – The threat of Public Cloud to IT departments
