About Course

About BIG DATA course

Is Big Data / Hadoop the big new word on the data streets? Of-course with the nature of IT world and applications evolving data has become the key resource. Every data in the various formats that it comes can be useful for the business. However, this isn’t easy. It comes with challenges like: single machine dependency, excessive amount of processing to fit this data into traditional Databases, performance issues, systems not being immune to failures etc.

Hadoop framework solves all this and brings in a level of efficiency and transparency into big data. Hadoop uses parallel and distributed processing to store data in multiple clusters across many systems. It is scalable, cheaper, faster, fault tolerant among various other things.

Hadoop has a huge scope for evolution and the demand for Big Data Hadoop professionals is and will be on a rise. Our Hadoop Big DATA course is just what you need to make you one of them.

What is Hadoop?

Hadoop is an open source computing framework that processes large data sets, in a distributed computing environment. High volume of data can be processed with ease by using parallel computing. Parallel computing is the back bone of Hadoop. Map Reduce development infrastructure, enables us to read, write and perform basic aggregation like operation on the stored data, in batches.

Why Hadoop?

Hadoop File System (HDFS) was made to store the huge amount of data. Companies like Yahoo, Facebook, Amazon, NYSE, LinkedIn, eBay, Sears and Walmart generate 30000 gigabytes of data every second. This data is now being used to generate various analytics. So it has to be stored. Traditional databases cannot handle data of this size. The Map Reduce infrastructure helps to run different kinds of diagnostics on them.

Significant features of our Hadoop Training
