The World of Hadoop and Beyond Hortonworks went through an IPO last Friday, December 12, 2014. It’s initial price of $16 soared by 60% immediately after. Today the stock price is $24.70 with a market cap of $1.02B. Another billion dollar club member. They compete with Cloudera and MapR in packaging the open source Hadoop platform for customers. How do they make money when the basic Apache Hadoop is free? – by offering added services like training and consulting. They can also add auxiliary products (not open source) that customers must pay for. The interesting fact is that Hortonworks’s CEO had claimed a $100m revenue this year, but looks like he is way short of that – $33m during first nine months. The future is quite uncertain! In the mean time, several new start-ups have come up in the Hadoop-sphere: Databricks with venture funding of $47m so far (includes Andrees... (more)

Data Lake and Data Refinery – Gartner Controversy! | @CloudExpo [#BigData]

Data Lake and Data Refinery – Gartner Controversy! Much discussion has been going on the new phrase called Data Lake. Gartner wrote a report on the ‘Data Lake’ fallacy, saying to be careful about ‘data lake’ or ‘data swamp’. Then Andrew Oliver wrote in the InfoWorld these beginning words, “For $200, Gartner tells you ‘data lakes’ are bad and advises you to try real hard, plan far in advance, and get governance correct”. Wow, what an insight! During my days at IBM and Oracle, Gartner wanted to get time on my calendar to talk about database futures. Then afterwards, I realized that... (more)

CES 2015 Theme: The 'Internet of Things' By @JnanDash | @ThingsExpo [#IoT]

This year’s CES expects to have 160,000 attendees and tonight’s keynote by the CEO of Samsung Mr. BK Yoon was “unlocking infinite possibilities of IoT”. The Internet of Things seems to be the overall theme this year. Today I listened to an interesting panel on disruptive technologies over next five years. Here is a brief summary. 3D Printing: This year expects to see 300,000 desktop 3D printers in the US. Mainstream consumer adoption is doubtful. Someone jokingly said that you can build a statue of yourself and install it in your yard. Another term for 3D printing is additive ma... (more)

Fast Data vs. Big Data By @JnanDash | @BigDataExpo [#BigData]

Fast Data vs. Big Data – How to Combine? Today, all the discussion on Big Data centers around “static data” in a data lake (old Data Warehouse) accessed by BI tools or SQL on Hadoop (Hawk, Impala) or Map/Reduce algorithms (MapR) for analysis. This is looking at historical data and finding trends. Some new tools are trying to provide predictive analysis based on past trends. This area deals with mostly the volume and variety aspect of Big Data, but not the velocity or for “data in motion.” The term “Fast Data” is applied to data that is in motion. This component is getting more ... (more)

Big Day at Apple – September 9, 2014

On September 9, 2014, Apple made significant announcements at the historic Flint Center in Cupertino, where exactly 30 years ago, the brand new Apple McIntosh was introduced by Steve Jobs. It is worthwhile to see the entire event (almost 1.5 hours, culminated by the band U2 playing on stage and releasing a new album on iTune for free download). Three key announcements were made: the new iPhone6 and iPhone6Plus, Apple Pay, and Apple Watch. The new iPhone6 and 6Plus offer bigger screen sizes, as expected, with a new chip plus new iOS8 software. Screen size went from 4 inch (iPhone5... (more)
