The Big Data course is designed to offer a comprehensive training on Hadoop Ecosystems and Big Data. The course will give a detailed insight behind the art of writing MapReduce programs and also enable understanding on management of large data sets with Pig Latin, Hive and HBase. The training also offers in-depth analysis on HDFS (Hadoop Distributed File System) and managing Hadoop Cluster.
How big is Big Data?
The growth of internet and advancement in real-time system has led to an increased requirement in proper storage of large dataset and enable quick access. This large records and new data-type generate from areas like social network sites and other real-time systems. This is what we refer as Big Data.
Let's see an example: Facebook stated that 500+ terabytes of new data gets added every day into their databases. "So what's the big deal here, Facebook can buy a dozen of hard disks every day to store this data". Storing the data is not a problem for Facebook, it’s the retrieval. Imagine how long it will take to search your Facebook photo into petabytes or exabytes of data that has been uploaded by users till now. You may end up waiting a couple of hours for sure.
Recent study indicates that there are more than 150 million personal blogs, Facebook has more than 700 million and Twitter has more than 250 million registered users. This clearly indicates such a gargantuan proportion of data generating each day and it needs proper management.
Big Data is usually classified by three main measurement approaches: Volume, Velocity and Variety.
Volume: A Home Computer has 1-2 TBs of storage. Today, a single one way flight from Mumbai to Delhi generate 200 TBs of flight data; Facebook ingest 500+ TBs of data every day; Online Stores, Health Care, are generating and storing very big amount of data. Large amount of data gets generated each day from real-time sources such as traffic control system.
Velocity: There was a time when we used to believe that yesterday's data is recent. Now a couple of minutes old messages and tweets are not interested to us. Clickstreams, Ad impressions saves millions of events every second; Stock trading changes, Mobile Phones, Online Videos, Real Time Gaming, Sensors etc. are generating millions of events per second. This high velocity represents BIG DATA.
Variety: Data isn't just numbers and strings now, real world have data in many different formats including 3D data, audio, video, unstructured text of log files, financial transactions and many more forms which we can expect to see in future. Traditional databases are unable to store and process this vast amount of unstructured and structured Big Data in a reasonable time frame.
What is the solution then?
There are some complex data management tools available to manage distribution of the data of which Hadoop is one common name that we often come across. Developed by Apache Foundation, it is an open source framework that facilitates storing and managing large set of data in a distributed environment.
Why learn Hadoop?
Hadoop can be considered as the most common requirement in IT sector for those who have planned for Big Data management. Understanding Hadoop offers a comprehensive idea behind the usage of the application. Moreover it helps to determine the pros and cons using the application when dealing with large data sets.
“Big Data” has come a long way and is probably the most significant contribution in the field of data management. The rise of this new technology is also increasing the requirement for quality professional and here, learning Hadoop comes in play for those willing to switch to this new domain.
There has never been a better time to get Hadoop training.
