AWS EMR

Amazon EMR (previously called Elastic MapReduce) is a cloud-based service offered by Amazon Web Services (AWS) that runs big data frameworks like Hadoop, Apache Spark, HBase, and Presto on AWS for data processing, machine learning, and data analysis-related tasks. It’s a managed service, so it removes the complexity of managing the big data infrastructure, i.e., it scales processing power based on data volume, and we only pay a per-second rate for what we use. In this lesson, we will learn about the features of EMR and how it works.
