I attended a Meetup yesterday in Mountain View, hosted by The Hive group on the subject of Lambda Architecture. Since I had never heard about this new phrase, my curiosity took me there. There was a panel discussion and panelists came from Hortonworks, Cloudera, MapR, Teradata, etc. Lambda Architecture is a useful framework to think about designing big data applications. Nathan Marz designed this generic architecture addressing common requirements for big data based on his experience working on distributed data processing systems at Twitter. Some of the key requirements in building this architecture include: Fault-tolerance against hardware failures and human errors Support for a variety of use cases that include low latency querying as well as updates Linear scale-out capabilities, meaning that throwing more machines at the problem should help with getting the job d...

Internet of Things and Big Data Coverage at CES 2015 By @JnanDash | @ThingsExpo [#IoT]

Big Data Coverage at CES 2015 I saw more discussion on big data at CES 2015 this week, compared to previous years. Everyone talked about data as the central core of everything. The IoT (Internet of Things), NFC (near Field Communication) and M2M (Machine to Machine) communication are enabling pieces for many industries  - security monitoring, asset and inventory tracking, healthcare, process control, building environment monitoring, vehicle tracking and telemetry, in-store customer engagement and digital signage. Big data is the big deal here. The Big Data ecosystem includes - cl... (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)

The World of Hadoop and Beyond By @JnanDash | @CloudExpo [#BigData]

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 Horto... (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)
