The Three Vs of Big Data

Data-intensive computing to unify, theorize, experiment, and do simulation at scale

Big Data is a top technology trend for 2012 according to Forrester Research. The Economist said that Big Data is a new game changing asset and The Harvard Business Review termed it as a scientific revolution. Scientific Revolution? Because it is data-intensive computing to unify, theorize, experiment, and do simulation at scale.

It is also termed the Fourth Paradigm – “The techniques and technologies for such data-intensive science are so different that it is worth distinguishing data-intensive science from computational science as a new, fourth paradigm for scientific exploration.”



Big Data is when the size of the data itself becomes part of the problem. But Big Data is not just “big”. There are the 3V’s of Big Data:

  1. Volume – Terabyte records, transactions, tables, files. A Boeing Jet engine spews out 10TB of operational data for every 30 minutes they run. Hence a 4-engine Jumbo jet can create 640TB on one Atlantic crossing. Multiply that to 25,000 flights flown each day and you get the picture.
  2. Velocity – batch, near-time, real-time, streams. Today’s on-line ad serving requires 40ms to respond with a decision. Financial services need near 1MS to calculate customer scoring probabilities. Stream data, such as movies, need to  travel at high speed for proper rendering.
  3. Variety – structures, unstructured, semi-structured, and all the above in a mix. WalMart processes 1M customer transactions per hour and feeds information to a database estimated at 2.5PB (petabytes). There are old and new data sources like RFID, sensors, mobile payments, in-vehicle tracking, etc.

Because of these characteristics, traditional DBMS solutions are inadequate. Hence we have seen the growth of technologies such as Hadoop (map-reduce algorithm started at Google) mostly processing unstructured data in batch mode. New solutions are needed for realtime processing.

"We're developing a software that is based on the cloud environment and we are providing those services to corporations and the general public," explained Seungmin Kim, CEO/CTO of SM Systems Inc., in this SYS-CON.tv interview at 21st Cloud Expo, held Oct 31 – Nov 2, 2017, at the Santa Clara Convention Center in Santa Clara, CA.
Enterprises are adopting Kubernetes to accelerate the development and the delivery of cloud-native applications. However, sharing a Kubernetes cluster between members of the same team can be challenging. And, sharing clusters across multiple teams is even harder. Kubernetes offers several constructs to help implement segmentation and isolation. However, these primitives can be complex to understand and apply. As a result, it’s becoming common for enterprises to end up with several clusters. Thi...

Data scientists must access high-performance computing resources across a wide-area network. To achieve cloud-based HPC visualization, researchers must transfer datasets and visualization results efficiently. HPC clusters now compute GPU-accelerated visualization in the cloud cluster. To efficiently display results remotely, a high-performance, low-latency protocol transfers the display from the cluster to a remote desktop. Further, tools to easily mount remote datasets and efficiently transfer...
WebRTC is great technology to build your own communication tools. It will be even more exciting experience it with advanced devices, such as a 360 Camera, 360 microphone, and a depth sensor camera. In his session at @ThingsExpo, Masashi Ganeko, a manager at INFOCOM Corporation, introduced two experimental projects from his team and what they learned from them. "Shotoku Tamago" uses the robot audition software HARK to track speakers in 360 video of a remote party. "Virtual Teleport" uses a multip...
