What is the “3rd Platform” of IT? It comprises of the cloud, mobile, social, and big data products. According to IDC, “3rd Platform technologies and solutions will drive 29 percent of 2014 IT spending and 89 percent of all IT spending growth”. Much of that growth will come from the “cannibalization” of traditional IT markets. Here are some interesting quotes and statements I read recently: Adding terabytes to a Hadoop cluster is much less costly than adding terabytes to an enterprise data warehouse (EDW). IDG Enterprise’s 2014 Big Data survey: more than half of the IT leaders polled believe they will have to re-architect the data center network to some extent to accommodate big data services. “Big data has the same sort of disruptive potential as the client-server revolution of 30 years ago, which changed the whole way that IT infrastructure evolved. For some peop... (more)

Hadoop & NoSQL – Friends, not frenemies (Published in SDTimes, January 7, 2014)

http://www.sdtimes.com/content/article.aspx?ArticleID=67541&page=1 The term Big Data is an all-encompassing phrase that has various subdivisions addressing different needs of the customers. The most common description of Big Data talks about the four V’s: Volume, Velocity, Variety and Veracity.Volume represents terabytes to exabytes of data, but this is data at rest. Velocity talks about streaming data requiring milliseconds to seconds of response time and is about data in motion. Variety is about data in many forms: structured, unstructured, text, spatial, and multimedia. Final... (more)

Real Time Big Data or Data in Motion

Most of the discussions on Big Data begins and ends with Hadoop. It is the commercial version of HPC (High Performance Computing), whose underlying technologies have been around for years: clustering, parallel processing, and distributed file system. In today’s parlance you can read Hadoop clusters on commodity hardware, map-reduce algorithm, and HDFS in that order. There is no doubt that Hadoop has taken off in a big way, but it does not address one big emerging area called real time query and analysis on data that is moving all the time. Data can be categorized into three bucke... (more)

The Future of Data Management According to Doug Cutting (Father of Hadoop)

I joined 600 people last night at a session sponsored by Hive to listen to Doug Cutting, the creator of Hadoop. Currently he is the chief architect at Cloudera and a director at Apache  Software Foundation. The hall at NetApp facility was overflowing with an eager audience. Doug spoke about the future of data management. He narrated a brief history of Hadoop, how it was founded and how far it has come. As everyone knows, the pedigree of Hadoop came from Google’s GFS (Google File System, now HDFS) and Map-Reduce programming. Here are the key predictions he made: Hadoop has grow... (more)

Internet of Things – IoT

This phrase “Internet of Things” is making big rounds these days, specially this week at CES (Consumer Electronic Show), Las Vegas. Not sure who came up with this, maybe Cisco in one of their self-serving predictions of the enormous growth of devices connected to the Internet (from about 10 billion today to 50 billion by 2020) and hence the need for their networking gear. John Chambers will elaborate this opportunity at CES in a keynote speech tomorrow. Gartner puts the number of connected devices at fewer than 30 billion, but sees $309 billion in additional revenue for products ... (more)
