Nancy Kopp for IBM data magazine:
Why is Hadoop the metaphorical bun for the big data burger?
Well, as Hadoop moved further into production environments,
two very prominent use cases emerged. We at IBM refer to the first use
case as the landing zone. It is an area of the architecture where
organizations are building out the capability
to land all data—both structured and unstructured. […]
The other prominent use case is leveraging Hadoop for archiving
and offloading the data warehouse.
That’s a pretty tasty comparison. But there’s something missing from this sandwich: the gravy—how is data moving between these layers? I’d bet that in most of the cases that’s still Hadoop.
