Seven Myths About Big Data
It may be clear that there is enough information to be found on the web regarding big data. Everyone has a different explanation of big data and what it can mean for organisations. With so much information around big data to be found, it is easy to become confused and to read the wrong information. So let’s dispel some of the most common big data myths and big data strategies.
1. Big Data is New
90% of the available data has been created in the last two years and the term big data has been around 2005, when it was launched by O’Reilly Media in 2005. However, the usage of big data and the need to understand all available data has been around much longer. There are a lot of examples of companies that were into big data before it was called big data. A well-known example is Walmart that has been using data analytics already for many years.
2. Big Data is Just a Hype
Big data is not something like social media, which indeed was a hype a few years back. At the beginning of social media everyone thought that social media was the Holy Grail, well it ended differently. Social media is just a marketing tool to better understand you customers. Big data on the other hand is a transformative trend that will mean a paradigm shift in all industries for all companies, big or small. The amount of data will only grow in the coming years and all that data can be turned into information that can be used to improve organisations in many different ways. Already, companies that have developed and implemented a big data strategy financially outperform their peers by 20%. This will only increase and companies that will not move into the direction of big data most probably will not be able to survive in the future.
3. You Need to Have a Lot of Data to Talk About Big Data
Big data does not necessarily have to be a lot of data. Although Volume is one of the three V’s that is generally used to describe big data, it is definitely not a requirement to have a minimum of for example a Petabyte of data. Especially the combination of different data sets (such as combining company data with social data and public data ) provides a lot of insights and this can also happen with smaller data sets.
4. Big Data is Only for Large Corporations
A small business has to look differently at big data, simply because less data is created. That does not mean however that small businesses cannot develop a big data strategy. Especially when small businesses start combining various data sets they can also obtain the insights that large corporations achieve with big data. It will however probably take a bit longer before small organizations will start to see the benefits of developing a big data strategy.
5. You Need to Hire a Big Data Scientist to Start With Big Data
There are many big data startups that offer innovative tools for companies as a SaaS or DaaS (Data-as-a-Service) solution. For each aspect of big data (processing, storing, analysing, visualizing) there are different startups that offer such a SaaS or DaaS solution. For these solutions there is no need at all to build a Hadoop cluster and to hire an expensive big data scientist or big data analyst.
6. Hadoop is the Holy Grail of Big Data
Hadoop offers a lot of advantages such as massive amounts of data that can be easily stored, processed and analyzed in a fraction of a second. It uses commodity hardware and can easily be scaled at relatively low costs. Combined with a fault tolerance system that copies all data several times over different clusters and nodes, Hadoop offers a lot of advantages. However, Hadoop is not the Holy Grail. There are quite some substantial disadvantages of Hadoop. Getting Hadoop operational is difficult and requires specialized engineers that are expensive. Subsequently cluster management is hard and debugging is pretty difficult and without a top layer real-time analytics is not possible. Therefore, using Hadoop is not a guarantee for success.
7. A Big Data Strategy is an IT Responsibility
Quite often, big data is seen as an IT matter, after all you need hardware and software to implement a big data strategy. It is true that the hardware and software need to be developed by highly skilled technical big data employees (in-house or outsourced). This is nothing strange, as the required IT of big data is different from what we have had so far. However, the required IT is merely a means to an end to achieve a big data strategy defined by the organization. This strategy could be “to increase customer satisfaction” or “to increase revenue” or “to improve the operational efficiency” and the route to achieve that strategy could be big data or any other solution for that matter. If the strategy is “to increase customer satisfaction” it would be strange to define it an IT matter or have the IT Director be the sponsor of the strategy. Therefore, big data is a strategy matter that should be dealt with, ideally, at board level.
