Introducing Big Data

When we say Big Data, we enter the petabyte space (1000 terabytes)

The phrase “Big Data” is thrown around a lot these days. What exactly is referred to by this phrase? When I was part of IBM’s DB2 development team, the largest size limit of a DB2 Table was 64 Gigabytes (GB) and I thought who on earth can use this size of a database. Thirty years later, that number looks so small. Now you can buy a 1 Terabyte external drive for less than $100.

Let us start with a level set on the unit of storage. In multiples of 1000, we go from Byte – Kilobyte (KB) – Megabyte (MB) – Gigabyte (GB) – Terabyte (TB) – Petabyte (PB) – Exabyte (EB) – Zettabyte (ZB) – Yottabyte (YB). The last one YB is 10 to the power of 24. A typed page is 2KB. The entire book collection at the US Library of Congress is 15TB. The amount of data processed in one hour at Google is 1PB. The total amount of information in existence is around 1.27ZB. Now you get some context to these numbers.

When we say Big Data, we enter the petabyte space (1000 Terabytes). There is talk of “personal petabyte” to store all your audio, video, and pictures. The cost has come down from $2M in 2002 to $2K in 2012 – real Moore’s law in disk storage technology here. This is not the stuff for current commercial database products such as DB2 or Oracle or SQLServer. Such RDBMS’s handle maximum of 10 to 100 Terabyte sizes. Anything bigger would cause serious performance nightmares. These large databases are mostly in the decision support and data warehousing applications. Walmart is known to have its main retail transaction data warehouse at 100 plus terabytes in a Teradata DBMS system.

Most of the growth in data is in “files”, not in DBMS. Now we see huge volumes of data in social networking sites like Facebook. At the beginning of 2010, Facebook was handling more than 4TB per day (compressed). Now that it has gone to 750M users, that number is at least 50% more. The new Zuck’s (Zuckerberg) law is , “Shared contents double every 24 months”. The question is how to deal with such volumes.

Google pioneered the algorithm called MapReduce to process massive amounts of data via parallel processing through hundreds of thousands of commodity servers. A simple Google query you type, probably touches 700 to 1000 servers to yield that half-second response time. MapReduce was made an open source under the Apache umbrella and was released as Hadoop (by Doug Cutting, former Xerox Parc, Apple, now at Cloudera). Hadoop has a file store called HDFS besides the MapReduce computational process. Hadoop therefore is a “flexible and available architecture for large scale computation and data processing on a network of commodity servers”. What is Redhat to Linux is Cloudera (new VC funded company) to Hadoop.

While Hadoop is becoming a defacto standard for big data, it’s pedigree is batch. For near-real-time analytics, better answers are needed. Yahoo, for example, has a real time analytics project called S4. Several other innovations are happening in this area of realtime or near realtime analytics. Visualization is another hot area for big data.

Big Data offers many opportunities for innovation in next few years.

If you’re responsible for an application that depends on the data or functionality of various IoT endpoints – either sensors or devices – your brand reputation depends on the security, reliability, and compliance of its many integrated parts. If your application fails to deliver the expected business results, your customers and partners won't care if that failure stems from the code you developed or from a component that you integrated. What can you do to ensure that the endpoints work as expect...
The Transparent Cloud-computing Consortium (abbreviation: T-Cloud Consortium) will conduct research activities into changes in the computing model as a result of collaboration between "device" and "cloud" and the creation of new value and markets through organic data processing High speed and high quality networks, and dramatic improvements in computer processing capabilities, have greatly changed the nature of applications and made the storing and processing of data on the network commonplace.
WebRTC adoption has generated a wave of creative uses of communications and collaboration through websites, sales apps, customer care and business applications. As WebRTC has become more mainstream it has evolved to use cases beyond the original peer-to-peer case, which has led to a repeating requirement for interoperability with existing infrastructures. In his session at @ThingsExpo, Graham Holt, Executive Vice President of Daitan Group, will cover implementation examples that have enabled ea...
Major trends and emerging technologies – from virtual reality and IoT, to Big Data and algorithms – are helping organizations innovate in the digital era. However, to create real business value, IT must think beyond the ‘what’ of digital transformation to the ‘how’ to harness emerging trends, innovation and disruption. Architecture is the key that underpins and ties all these efforts together. In the digital age, it’s important to invest in architecture, extend the enterprise footprint to the cl...
Cognitive Computing is becoming the foundation for a new generation of solutions that have the potential to transform business. Unlike traditional approaches to building solutions, a cognitive computing approach allows the data to help determine the way applications are designed. This contrasts with conventional software development that begins with defining logic based on the current way a business operates. In her session at 18th Cloud Expo, Judith S. Hurwitz, President and CEO of Hurwitz & ...
Fifty billion connected devices and still no winning protocols standards. HTTP, WebSockets, MQTT, and CoAP seem to be leading in the IoT protocol race at the moment but many more protocols are getting introduced on a regular basis. Each protocol has its pros and cons depending on the nature of the communications. Does there really need to be only one protocol to rule them all? Of course not. In his session at @ThingsExpo, Chris Matthieu, co-founder and CTO of Octoblu, walk you through how Oct...

The vision of a connected smart home is becoming reality with the application of integrated wireless technologies in devices and appliances. The use of standardized and TCP/IP networked wireless technologies in line-powered and battery operated sensors and controls has led to the adoption of radios in the 2.4GHz band, including Wi-Fi, BT/BLE and 802.15.4 applied ZigBee and Thread. This is driving the need for robust wireless coexistence for multiple radios to ensure throughput performance and th...
Enterprise IT has been in the era of Hybrid Cloud for some time now. But it seems most conversations about Hybrid are focused on integrating AWS, Microsoft Azure, or Google ECM into existing on-premises systems. Where is all the Private Cloud? What do technology providers need to do to make their offerings more compelling? How should enterprise IT executives and buyers define their focus, needs, and roadmap, and communicate that clearly to the providers?
