    Apache Hadoop and Big Data: What are they?

    Big Data

    Big data refers to a collection of complex and large data sets, which is difficult to process and store using traditional methods or database management. It is a vast subject that involves various frameworks, techniques, and tools.

    Big data constitutes data that different applications and devices produce, such as Black box, transport, search engine, stock exchange, power grid, social media, and the list goes on.

    The different processes included in Big Data are capturing, storing, curating, sharing, searching, transferring, visualizing, and analyzing data. There are three formats of Big data: Structured data, unstructured data, and semi-structured data.

    The benefits of Big Data are:

    • Boosts organizational efficiency while cutting down extra expenses
    • Helps you tailor your offerings based on the needs, demands, beliefs, and shopping preferences of customers for better sales and branding
    • Ensure that the right employees are hired
    • Results in better decision-making
    • Fuels innovation with deeper insights
    • Improvement in healthcare, educational, and other sectors
    • Pricing optimization for your product and services

    Apache Hadoop

    Apache Hadoop is an open-source software framework that organizations utilize to store data in a large amount and perform computation. The basis of this framework is Java, along with certain native codes in C and shell scripts.

    The Apache Software Foundation developed Hadoop in 2006. It is basically a tool to process big data and make it more meaningful to generate more revenue and reap other benefits. It implies that the ecosystem of Hadoop has the capability to solve Big Data, and this is how they are related, in case you are wondering.

    The different components of the Hadoop ecosystem are TEZ, Storm, Mahout, MapReduce, etc. Hadoop is affordable yet highly scalable, flexible, and includes fault tolerance in its prized feature list. This is why its adoption is growing rapidly.

    The benefits of Hadoop are:

    • The capability of storing and processing huge amounts of data in a distributed way
    • Faster and high computing power
    • Great fault tolerance, as data processing is protected from hardware failure. Even if a node fails, the job is redirected automatically to other nodes, ensuring the computing never fails.
    • It allows you to scale your system easily to tackle more data by adding more nodes.
    • The flexibility to store any amount of data and then use it however you want
    • As Hadoop is a free, open-source framework, you save a lot of money compare to an enterprise solution.

    How are enterprises adopting Big Data and Hadoop?

    Hadoop and Big Data have great market prospects across different industry verticals. In this digital age, billions and trillions of data are being produced with emerging technologies. And these technologies are efficient to store this massive data and process it so enterprises can grow even more.

    From e-commerce, media, telecom, and banking to healthcare, government, and transportation, industries have benefited from data analytics; hence, Hadoop and Big Data’s adoption is skyrocketing.

    But how?

    Look at some of the industries and how they implement Big Data.

    • Media, communication, and entertainment: Businesses use Hadoop and Big Data Analytics to analyze customer behavior. They use the analysis to serve their customers accordingly and tailor content based on their target audience.
    • Education: businesses in the education sector use the technologies to track student behavior and their progress over time. They also use it to track instructors or teachers’ performance based on the subject matter, student count and their progress, etc.
    • Healthcare: Institutions use public health insights and visualize to track disease spreading and work on active measures sooner.
    • Banking: Big banks, retail traders, and fund management firms leverage Hadoop for sentiment measurement, pre-trade analytics, predictive analytics, social analytics, audit trails, etc.
