Hadoop and Big Data is one of the most used extract, transform, and load (ETL) tools these days. Most of the companies are using it to fetch more and more information from the data available with them. But sometimes it is found that creating and maintaining the Hadoop cluster is quite a time-consuming job, especially when you don't have much exposure to the Linux/Unix environment. Also, if you need to use Hadoop in production, you would need to hire a specialist Hadoop admin, which is an overhead in terms of cost. To solve this, AWS has introduced a hosted Hadoop as a service where you just need to provide your requirement in terms of cluster configuration (number of data nodes and the size of instances based on the size of data you want to process), additional services such as Hive, Pig, and so on, if required, and once done, on a single click of the button, you have your Hadoop cluster ready.
