Introduction to Big Data

Currently, the data that needs to be structured and formatted is over 80% due to the constant development and advancement in the whole wide world. This unstructured data contains recordings, images, tracking details of GPS, videos, audios, and sensor records. As we are moving forward in the advanced age, the data to be formatted is piling up enormously, thus; to store and structure this amount of big data we need more efficient resources.

There is a strong need to give a certain structure to the data because it helps the businesses to make vital decisions for organizations in the long run. The statistics given by this data can consummately provide the enterprises to take risks and put themselves out there in the competitive market to achieve bigger goals.

Big Data Systems Characteristics

The data of today's world is no more similar to the data produced in the past. Therefore, we need such big data systems that have some of the most significant characteristics which are mentioned below.

  • The data systems must be able to store large bulks of data, thus; exhibiting greater volume for storage.
  • Today, the data comes in all the sizes and shapes, therefore; we should opt for those big data systems that show a variety of systems to give structure and format to the data.
  • Millions of data are getting produced in a minute all over the world by social media and other systems so it must be handled vigilantly at a faster pace as it comes.
  • The big data systems must be able to provide accurate and certain information to the enterprises.

What is Apache Hadoop?

Apache Hadoop is a system of big data that is certified to tackle any obstacle coming in the way. It is a kind of open-source operating system which is based on an effective programming language known as Java. Apache Hadoop utilizes a skilled framework for the processing of obscure and plethora of data by distributing it in several streamlined programming systems.

Apache Hadoop is a single server but it spreads to miscellaneous networks that are further connected to the machines to provide high productivity, increased efficiency, and enhanced effectiveness. All of this can only be pulled off by the experts which have the authentic Hadoop Certifications to carry out all the vital functions.

Components of Apache Hadoop

There are some of the notable components of Apache Hadoop that are significant in bringing about the responsibilities that Hadoop is entrusted upon with.

  • At the layer of the application, all the problems and discrepancies are handled and detected by a Library.
  • The bottom layer consists of storage which is guarded by Hadoop Distributed File System (HDFS) which helps to process the stored data in several chunks that are efficiently transmitted across by the help of cluster nodes.
  • MapReduce to critically cut down specific parts of the data which is also referred to as parallel processing.
  • Management of cluster resources and scheduling of the job requires Yarn.

Role of Apache Hadoop in Big Data

As the information continues to pile up and it has been difficult to control the avalanche of data, there was a dire need to produce a system to control, handle, manage, and process the over-abundance of such data. That is why Apache Hadoop came into being which has several roles to play in the big data.

  1. Storage at Lower Costs

The foremost thing which is concerning is the storage of the big data and Apache Hadoop is designed to provide such storage at much lower costs than any other systems. It can store large chunks of data for hundreds of dollars at each terabyte whereas the other systems cost you thousands of dollars for the storage of data of the same capacity.

  1. Tolerance of Fault

The processing and structuring of data are prone to get faulty, wary, and sometimes, it may also counterfeit the original data. To save your business data from such calamity, Apache Hadoop is used because even if some bits of the data may get faulty at a certain node, it will be quickly recovered or replicated before transferring it to the next node. Moreover, the recovery can also be stored in the forms of failures of rack and disk.

  1. Variety and Velocity

Apache Hadoop provides the said amount of velocity in processing the data and gives out the essential information to the enterprises on time. It keeps us with the daily incoming of the data into the systems and it uses a variety of tools and techniques to structure all kinds of data into meaningful and fruitful outcomes.

  1. Security to the Big Data

Due to the efficient use of tools and techniques by the Apache Hadoop, it is used to locate the cyber-attacks on the system. It is also being used to identify the attackers that try to gain unauthorized access to your systems by going through every node and step by step. In some countries, it is also used to counter-attack terrorism.


Apache Hadoop is undoubtedly a magnificent creation and only the professionals have the chance to become part of the movement. Therefore, one must have the proper Hadoop Certifications to jump over any hurdle that comes in his/her way. Our certifications will provide you all the training that you need and they also polish up your talents by nourishing them with enhanced learning
