10 Top Commercial Hadoop Platforms via @Data_Informed @BernardMarr

Bernard Marr shares his view of several commercial Hadoop distributions on Data Informed.

Many of the companies that offer Hadoop (including some on his list) offer their own version of the open source software.  As he points out, many of them are within their own cloud and therefore are via a subscription.  I have a concern as to how easy it would be to then change vendor and not lose functionality or data in some form.  Or even if you then get stuck being tied to a vendor and having to pay increasingly higher costs. Something that needs to be taken into account when picking a vendor.
