Relevance of Big Data
In today’s world, where operations are entirely dependent on business intelligence and utilize the platform of information warfare for execution of the same, data has become one of the most vital entities for execution of business and it is very difficult to discard any form of data because regardless of how irrelevant it may seem, the possibility stands that it might be an ancillary structure to develop other form of relevant results. Large amounts of data of diverse nature is generated all over the world, in all forms, both structured and unstructured. The vitality of the big data is such that its growth and demand has accelerated exponentially, to a point where storage of the same has become a looming challenge; for instance, one may consider a social media interface such has Facebook and try and fathom how many likes are received by the website for all the uploads made by all the users over the year. One can say it is impossible to store data with such a borderline-infinite girth and hence can only be recorded over multiple machines, this data is known as big data.
Big data is characterized by three vital aspects, volume, velocity and variety of its generation. As we insinuated earlier, big data can be generated at large volumes, the data is generated from various sources, which may bestow it with a variety formats and depending on type of data and nature of its origin, it may be generated at variable speeds. The data may be generated at an extraordinary rate of speed and hence may require advanced or for that matter state-of-the-art hardware and software components.
Big data has become vital to our existence, in consideration one may take into account the recommendations provided by the e-commerce sites based on our search queries of for that matter analysis of our interests based on an acute analysis of our browser history and other frequent activities.
As one may understand the size of such data may be ever-increasing and here a problem is imposed, how should one approach analysis and execution of such a data without compromising on quality or hampering reliability. To ensure effective management state-of-the-art big data handling software, such as Hadoop are utilized. Hadoop uses simple models of programming that divides the data into clusters that can be further analyzed and hence provides the user with an ease of approach. This data is then executed in two consecutive stages, which are; first the data is converted into a Hadoop Distributed File System (HDFS) and then the data is subjected to a process called Mapreduce. The series of machines running Mapreduce and HDFS together constitute, what are known as clusters. Nodes or the machines that are used to carry out these operations sort the data in a 64mb pieces and spread across the cluster which is then replicated three times. This culminates the storage aspect of the process and then Mapreduce initiates analysis. The required tasks are distributed to every node and when the individual machines complete the tasks, the completed data is collected, mapped and reduced by the process of shuffling and sorting, which makes the analysis of big data easy and fast with no difficulties.
With more and more companies making the transition into the big data market and those that are not making the transition are incorporating and utilizing big data to harness benefits of optimizing corporate efficiency, it is imminent that the gradual exponential growth of big data will result in abundance of new career and revenue generation opportunities. It is vital that one equips themselves with the relevant skill-set and proficiency to enable themselves to capitalize on this situation.
