Every day, people send 150 billion new email messages. The number of mobile devices already exceeds the world's population and is growing. With every keystroke and click, we are creating new data at a blistering pace.

This brave new world is a potential treasure trove for data scientists and analysts who can comb through massive amounts of data for new insights, research breakthroughs, undetected fraud or other yet-to-be-discovered purposes. But it also presents a problem for traditional relational databases and analytics tools, which were not built to handle the data being created. Another challenge is the mixed sources and formats, which include XML, log files, objects, text, binary and more.

"We have a lot of data in structured databases, traditional relational databases now, but we have data coming in from so many sources that trying to categorize that, classify it and get it entered into a traditional database is beyond the scope of our capabilities," said Jack Collins, director of the Advanced Biomedical Computing Center at the Frederick National Laboratory for Cancer Research. "Computer technology is growing rapidly, but the number of [full-time equivalent positions] that we have to work with this is not growing. We have to find a different way."

Enter Apache Hadoop, an open-source, distributed programming framework that relies on parallel processing to store and analyze tremendous amounts of structured and unstructured data. Although Hadoop is far from the only big-data tool, it is one that has generated remarkable buzz and excitement in recent years. And it offers a possible solution for IT leaders who are realizing that they will soon be buried in more data than they can efficiently manage and use.

New open-source and commercial software from Big Switch Networks threatens longtime hardware sellers as it lets customers introduce and manage commodity switches.

Hot off a new round of funding, Big Switch Networks says it now has open-source and commercial software to help companies scale out networks more easily and cheaply with commodity switches, further threatening the likes of legacy network gear sellers.

Big Switch’s new Switch Light software implements the OpenFlow networking protocol in physical and virtual switches. It lets data center administrators automatically and centrally send out policies from one location when new switches are added to the network, instead of having to go through with a time-consuming, hands-on process.

The open-source version of Switch Light is available for free because “we want to make sure (OpenFlow) industry standards are enabled in the data plane,” said Jason Matlof, vice president of marketing at Big Switch. The commercial version comes with technical support and is more scalable and highly available than the open-source version, Matlof said.

Switch Light is based on existing open-source technology developed a few years ago under the name Indigo. Customers can sign up to use the Switch Light software under a licensing agreement along with Big Switch’s other software-defined networking products — the Big Switch Controller for the network’s control plane, the Big Virtual Switch and the Big Tap monitoring program.

Consider the news another blow to Cisco, as the Big Switch software is aimed at customers that want to move away from lock-in from the legacy network hardware vendor and shift elements of their network stacks to white-label suppliers. Cisco still holds 65 percent of marketshare for Ethernet switches. Arista and Juniper play here, too.
