Here’s a very good chart of big data eco-system prepared by Matt Turck and Shivon Zilis (see this link for more). Like the way they have classified major big data players across Infrastructure, Analytics, Applications and Data Sources.
My take on this ecosystem is that we are going to see a lot of action on big data analytics front as it is the analytics layer where major value addition happens in Big Data stack – others, namely Infrastructure, Application and Data Sources are geared for collection and storage of information that is used by Analytics layer for deriving insights for decision making.
