InsightaaS: Founded in 2009, SiliconANGLE provides IT news and analysis focused on "where computer science intersects social science." In this post, Wikibon analyst Jeffrey Kelley asks, and then answers, the question "Will Hadoop replace your enterprise data warehouse (EDW)?" The article states that Hadoop "is not going to outright replace your EDW," but highlights areas in which Hadoop offers a cost-effective means of supporting compute and storage-intensive EDW workloads, and others where Hadoop provides capabilities that are beyond traditional EDW systems. In the end, each approach will have discrete strengths, and there will be overlap between them - challenging vendors to create effective positioning, and giving enterprises a richer set of tools with which to approach the "data economy."
