"We want to do Hadoop in the cloud." That's what we increasingly hear from enterprises that have successfully run on-premises Hadoop proof-of-concepts. CIOs charge their enterprise architecture (EA) pros with understanding the strengths and weaknesses of Hadoop in the cloud and to make the case for it versus on-premises deployments. Forrester's 37-criteria evaluation of eight leading big data Hadoop cloud solution vendors — Altiscale, Amazon Web Services (AWS), Google, IBM, Microsoft, Oracle, Qubole, and Rackspace — will help EA pros understand the available solutions and recommend the best one for their organization.
