Picking Winners In Big Data Neeraj-Nathani SmartBridge



Picking Winners In Big Data
Big data solutions are picking up speed in the IT industry. There’s a Cambrian explosion of interesting start-ups, and all the database and business intelligence incumbents have moved to create big data offerings, or rebrand into the new universe.
The key to seeing the value of big data is understanding that it’s a business problem, not a matter of picking the right tools and waiting for the magic to happen. That said, technology choices still need to be made in an increasingly crowded and confused market.
The biggest question for anybody wanting to invest or adopt technology in this area is how to pick the winner? Glancing through marketing materials will do little to help you: everybody claims relevance to big data.
As I am often asked my opinion about big data companies, I thought I’d share some of the principles I use to help me think about the industry.
Where’s the value?
We need to understand where the actual value is in the data world. For the most part, this value doesn’t lie purely in the software. Over the past decade we have seen a rising tide of commoditization of the software stack: from operating system, to relational databases, to Hadoop itself. In fact, without this, we wouldn’t have the big data revolution as we know it.
As Hadoop has become a de facto standard, so has the notion of building on top of it with open source. There is some advantage in software innovation, but it is momentary. Once something is known to be possible, there are enough smart programmers out there that reproducing it becomes straightforward. (Because of this, I gloomily predict no shortage of patent battles in the not-too-distant future.)
Despite the flux in the software world, two things about big data remain constant: the need for compute and storage, and data itself. It’s ultimately to ownership of one or both of these factors that IT industry value will gravitate.
Compute and storage
The ever growing need for computing power and storage bodes well for companies providing the basics. These fall into two categories: hardware manufacturers, and cloud infrastructure providers. Not that these two markets are immune to their own fluctuations, thanks to standardization and commoditization, but fundamentally, getting paid for use of metal is the name of the game.
In this respect, it’s not too much of a mystery why storage company EMC has plowed so early and so deep into the big data world. Neither is it hard to see the reasoning behind Intel creating its own optimized Hadoop distribution.
Data
Value resting in data is the more subtle of the two axes of big data success.
Big data is ultimately about the smart use of data to drive a business. There are two kinds of data: data about your business, and data external to your business that you can create value from.
It’s easy to see who might get success from the latter, external data. We can expect that massive data owners such as Google, Facebook, Thomson Reuters, Bloomberg will experience ongoing success for as long as they are able to create product from their data.
Who owns your data, though? The obvious answer, you, isn’t the only answer. In fact, your data is locked up inside the platform choices you make, at both the hardware and software level. If your systems are based on Oracle, Microsoft, you are very unlikely to move in a hurry. Data likes to stay where it is, and tends to attract more data as you build systems around it. Production systems are expensive to replace.

So, the vendors of your software platforms of choice also get long term value from your data. For this reason, it’s hard to bet against existing enterprise application platform incumbents in the big data world. Big data, for most of today’s organizations, is an additive phenomenon, not a challenge to the core of IT.
We’ll see more large platforms ensuring nobody needs to move away. Examples include SAP adding HANA, in order to enable their existing customers for big data, or Amazon Web Services’ addition of their data warehouse Redshift, to ensure that the entire data needs of a company can be met on their platform.
Finally, it would be lunacy to bet against either Oracle, who have been portentously quiet in the big data world over the last year, or Microsoft, who in Excel have the world’s most popular data manipulation environment.
It is all business as usual?
I’m not saying there is no new opportunity in the big data industry. What I am saying is that, as an additive technology, big data is unlikely to enable anybody to challenge Oracle or Microsoft for the throne.
There will be change, though, and it will bring both winners and losers.
The area of value we haven’t yet looked at yet is the point where data interacts with the actual mechanism of a business. That’s where it transfers value to you and enables you to leverage data to get ahead. This breaks down into several areas of opportunity for big data innovators.
  • Domain specific: tools that enable the manipulation and exploitation of data in a way that’s specific to a business segment. We see initial evidence of this market opportunity in the evolution of web and customer analytics products.
  • Machine learning: more data means more to understand, and the only way an organization can realistically do this is with the aid of computers. Machine learning helps automate many parts of the data wrangling process. Furthermore, cross-company data sharing can significantly boost the effectiveness of machine-learning, creating the opportunity for companies gaining early market share. A recent example of this is Sift Science, a fraud detection application.
  • Tools for exploration: human interaction with data is a requirement that’s hard to abstract away. Tableau has a head start in this market for big data, filling the role of “Microsoft Office for Data”, but the field is ripe for new innovation, especially with the increasing power of graphical capabilities and new device formats.
  • Data agility: speed-to-decision is a critical factor in business competitiveness. Any solution that removes laborious steps has an advantage: a particularly problematic area here is data integration, the loading of both internal and external data sources ready for analytics. Most of today’s big data solutions are frankensteined combinations of layers: there’s a great opportunity for vertically integrated solutions that removes needless impedance to data manipulation.

Areas of risk
What are those riskier big data options? If a solution isn’t scoring high in the categories above, it’s not likely to be around for the long run.
The biggest risk is with solutions that address only a single horizontal part of the data architecture. Time is against companies in this game. By selling just part of a complete solution, they’re working against the rising tide of commoditization. Customers will demand standardization (e.g. Hadoop compatibility) in order to feel safe adopting such solutions, but that prevents the lock-in that will protect that business. It’s not Oracle’s relational database that cements their position: it’s their vertical position up and down the application stack.
Therefore, it’s not surprising to see the pure Hadoop distribution companies making partnerships, and branching out into other vertical layers. In the long term, it’s a tough road they’ve chosen.
One company working actively to solve this problem is DataStax, who have pivoted from being seen as the corporate backer for the Cassandra NoSQL database—a risky horizontal play—to selling an integrated stack of Cassandra, Hadoop and Solr, intended as a complete platform for building enterprise applications. They’re going after some of the platform business: being involved in the actual use of data to drive business value.
For some start-ups, not having long term big data viability might be just fine as a strategy. As the bigger enterprise companies lumber into the arena, they’ll prove handy acquisitions. But given the crowded space and progressive commoditization, this isn’t a certain future. And certainly for their customers, the risks are growing.
More controversially, another area at risk is that of traditional ETL. Or in its broader sense, data integration. This is a hard, hard, problem. It’s not easy to integrate data retrospectively, and it’s not all certain that the integration players from the data warehouse world will be able to translate that success into the big data world. Many early adopters of Hadoop were motivated by the fact that existing ETL solutions couldn’t meet their needs.
In the long term, data integration is likely to be best served by entire new architectures that don’t try to separate and tame the data in the first place. It’s a lot easier to build truly integrated data infrastructure as greenfield.
For those who crack the integration problem, the potential rewards are high. But so is the risk.
Conclusion
In the long term, the additive nature of big data, combined with inertia, makes it a safe bet that current enterprise IT incumbents will continue their reign, as long as they move to embrace big data in their architectures.
There is plenty of opportunity though, especially in greenfield and cloud scenarios. Expect to see increasing returns for those who provide integrated solutions and do a good job of equipping human decision makers.
There’s long term value in metal, and value in data. About everything else, it’s worth thinking carefully.

Big data Neeraj-Nathani SmartBridge



Big data
Big data[1][2] is a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications. The challenges include capture, curation, storage,[3] search, sharing, transfer, analysis,[4] and visualization. The trend to larger data sets is due to the additional information derivable from analysis of a single large set of related data, as compared to separate smaller sets with the same total amount of data, allowing correlations to be found to "spot business trends, determine quality of research, prevent diseases, link legal citations, combat crime, and determine real-time roadway traffic conditions."[5][6][7]
As of 2012[update], limits on the size of data sets that are feasible to process in a reasonable amount of time were on the order of exabytes of data.[8][9] Scientists regularly encounter limitations due to large data sets in many areas, including meteorology, genomics,[10] connectomics, complex physics simulations,[11] and biological and environmental research.[12] The limitations also affect Internet search, finance and business informatics. Data sets grow in size in part because they are increasingly being gathered by ubiquitous information-sensing mobile devices, aerial sensory technologies (remote sensing), software logs, cameras, microphones, radio-frequency identification readers, and wireless sensor networks.[13][14] The world's technological per-capita capacity to store information has roughly doubled every 40 months since the 1980s;[15] as of 2012[update], every day 2.5 quintillion (2.5×1018) bytes of data were created.[16] The challenge for large enterprises is determining who should own big data initiatives that straddle the entire organization.[17]
Big data is difficult to work with using most relational database management systems and desktop statistics and visualization packages, requiring instead "massively parallel software running on tens, hundreds, or even thousands of servers".[18] What is considered "big data" varies depending on the capabilities of the organization managing the set, and on the capabilities of the applications that are traditionally used to process and analyze the data set in its domain. "For some organizations, facing hundreds of gigabytes of data for the first time may trigger a need to reconsider data management options. For others, it may take tens or hundreds of terabytes before data size becomes a significant consideration."[19].

Definition

Big data usually includes data sets with sizes beyond the ability of commonly used software tools to capture, curate, manage, and process the data within a tolerable elapsed time. Big data sizes are a constantly moving target, as of 2012[update] ranging from a few dozen terabytes to many petabytes of data in a single data set. With this difficulty, new platforms of "big data" tools are being developed to handle various aspects of large quantities of data.
In a 2001 research report[20] and related lectures, META Group (now Gartner) analyst Doug Laney defined data growth challenges and opportunities as being three-dimensional, i.e. increasing volume (amount of data), velocity (speed of data in and out), and variety (range of data types and sources). Gartner, and now much of the industry, continue to use this "3Vs" model for describing big data.[21] In 2012, Gartner updated its definition as follows: "Big data are high volume, high velocity, and/or high variety information assets that require new forms of processing to enable enhanced decision making, insight discovery and process optimization."[22


Examples

Examples include Big Science, web logs, RFID, sensor networks, social networks, social data (due to the social data revolution), Internet text and documents, Internet search indexing, call detail records, astronomy, atmospheric science, genomics, biogeochemical, biological, and other complex and often interdisciplinary scientific research, military surveillance, forecasting drive times for new home buyers, medical records, photography archives, video archives, and large-scale e-commerce.

Big science

The Large Hadron Collider experiments represent about 150 million sensors delivering data 40 million times per second. There are nearly 600 million collisions per second. After filtering and refraining from recording more than 99.999% of these streams, there are 100 collisions of interest per second.[23][24][25]
  • As a result, only working with less than 0.001% of the sensor stream data, the data flow from all four LHC experiments represents 25 petabytes annual rate before replication (as of 2012). This becomes nearly 200 petabytes after replication.
  • If all sensor data were to be recorded in LHC, the data flow would be extremely hard to work with. The data flow would exceed 150 million petabytes annual rate, or nearly 500 exabytes per day, before replication. To put the number in perspective, this is equivalent to 500 quintillion (5×1020) bytes per day, almost 200 times higher than all the other sources combined in the world.

Science and research

  • When the Sloan Digital Sky Survey (SDSS) began collecting astronomical data in 2000, it amassed more in its first few weeks than all data collected in the history of astronomy. Continuing at a rate of about 200 GB per night, SDSS has amassed more than 140 terabytes of information. When the Large Synoptic Survey Telescope, successor to SDSS, comes online in 2016 it is anticipated to acquire that amount of data every five days.[5]
  • Decoding the human genome originally took 10 years to process; now it can be achieved in one week.[5]
  • Computational social science — Tobias Preis et al. used Google Trends data to demonstrate that Internet users from countries with a higher per capita gross domestic product (GDP) are more likely to search for information about the future than information about the past. The findings suggest there may be a link between online behaviour and real-world economic indicators.[26][27][28] The authors of the study examined Google queries logs made by Internet users in 45 different countries in 2010 and calculated the ratio of the volume of searches for the coming year (‘2011’) to the volume of searches for the previous year (‘2009’), which they call the ‘future orientation index’.[29] They compared the future orientation index to the per capita GDP of each country and found a strong tendency for countries in which Google users enquire more about the future to exhibit a higher GDP. The results hint that there may potentially be a relationship between the economic success of a country and the information-seeking behavior of its citizens captured in big data.

Government

Private sector

  • Amazon.com handles millions of back-end operations every day, as well as queries from more than half a million third-party sellers. The core technology that keeps Amazon running is Linux-based and as of 2005 they had the world’s three largest Linux databases, with capacities of 7.8 TB, 18.5 TB, and 24.7 TB.[37]
  • Walmart handles more than 1 million customer transactions every hour, which is imported into databases estimated to contain more than 2.5 petabytes (2560 terabytes) of data – the equivalent of 167 times the information contained in all the books in the US Library of Congress.[5]
  • Facebook handles 50 billion photos from its user base.
  • FICO Falcon Credit Card Fraud Detection System protects 2.1 billion active accounts world-wide.[38]
  • The volume of business data worldwide, across all companies, doubles every 1.2 years, according to estimates.[39]
  • Infosys has also launched the BigDataEdge to analyse the Big data.[40][41]
  • Windermere Real Estate uses anonymous GPS signals from nearly 100 million drivers to help new home buyers determine their typical drive times to and from work throughout various times of the day [42]

International development

Following decades of work in the area of the effective usage of information and communication technologies for development (or ICT4D), it has been suggested that Big Data can make important contributions to international development.[43][44] On the one hand, the advent of Big Data delivers the cost-effective prospect to improve decision-making in critical development areas such as health care, employment, economic productivity, crime and security, and natural disaster and resource management.[45] On the other hand, all the well-known concerns of the Big Data debate, such as privacy, interoperability challenges, and the almighty power of imperfect algorithms, are aggravated in developing countries by long-standing development challenges like lacking technological infrastructure and economic and human resource scarcity. "This has the potential to result in a new kind of digital divide: a divide in data-based intelligence to inform decision-making."[45]
Technologies
DARPA’s Topological Data Analysis program seeks the fundamental structure of massive data sets.
Big data requires exceptional technologies to efficiently process large quantities of data within tolerable elapsed times. A 2011 McKinsey report[49] suggests suitable technologies include A/B testing, association rule learning, classification, cluster analysis, crowdsourcing, data fusion and integration, ensemble learning, genetic algorithms, machine learning, natural language processing, neural networks, pattern recognition, anomaly detection, predictive modelling, regression, sentiment analysis, signal processing, supervised and unsupervised learning, simulation, time series analysis and visualisation. Multidimensional big data can also be represented as tensors, which can be more efficiently handled by tensor-based computation,[50] such as multilinear subspace learning.[51] Additional technologies being applied to big data include massively parallel-processing (MPP) databases, search-based applications, data-mining grids, distributed file systems, distributed databases, cloud based infrastructure (applications, storage and computing resources) and the Internet.[citation needed]
Some but not all MPP relational databases have the ability to store and manage petabytes of data. Implicit is the ability to load, monitor, back up, and optimize the use of the large data tables in the RDBMS.[52]
DARPA’s Topological Data Analysis program seeks the fundamental structure of massive data sets and in 2008 the technology went public with the launch of a company called Ayasdi.
The practitioners of big data analytics processes are generally hostile to slower shared storage[citation needed], preferring direct-attached storage (DAS) in its various forms from solid state disk (SSD) to high capacity SATA disk buried inside parallel processing nodes. The perception of shared storage architectures—SAN and NAS—is that they are relatively slow, complex, and expensive. These qualities are not consistent with big data analytics systems that thrive on system performance, commodity infrastructure, and low cost.
Real or near-real time information delivery is one of the defining characteristics of big data analytics. Latency is therefore avoided whenever and wherever possible. Data in memory is good—data on spinning disk at the other end of a FC SAN connection is not. The cost of a SAN at the scale needed for analytics applications is very much higher than other storage techniques.
There are advantages as well as disadvantages to shared storage in big data analytics, but big data analytics practitioners as of 2011[update] did not favour it.[53]
