Spoilt for Choice – How to choose the right Big Data / Hadoop Platform?

Almost all big software vendors such as IBM, Oracle, SAP, or even Microsoft use it. However, when you have decided to use Hadoop, the first question is how to start and which product to choose for your big data processes. Several alternatives exist for installing a version of Hadoop and realizing big data processes. This article discusses different alternatives and recommends when to use which one.
