Open Enterprise Interview: Mike Olson, Cloudera
Yesterday, I wrote about the launch of the open source company Cloudera.
It's always hard to tell whether startups will flourish, but among the most critical factors for survival are the skills of the management team. The fact that less than three hours after I sent out some questions about Cloudera to Mike Olson, one of the company's founders, I had the answers back would seem to augur well in this respect.
Olson explains the background to the company, and to Hadoop, the software it is based on: what it does, and why business might want to use it; he talks about his company's services and business model, and why he thinks cloud computing is neither a threat nor an opportunity for open source.
GM: What's the history of the Hadoop project?
MO: Google developed its MapReduce technology beginning in the very early part of this decade in order to process the huge amounts of data it collected in its web crawls. Google, like other web properties that operate at scale - Amazon, Facebook, Yahoo and others - builds its infrastructure from cheap servers with lots of local storage. The MapReduce software was designed to run well and to scale easily on unreliable hardware.
MapReduce is able to survive disc and server failures without interrupting jobs and without losing data. Google published a widely-read paper on MapReduce in 2004. Doug Cutting, the engineer behind the Lucene and Nutch open source projects, read the paper and decided he would like to build an open source implementation of MapReduce.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
