AWS EMR

Amazon EMR (previously called Elastic MapReduce) is a cloud-based service offered by Amazon Web Services (AWS) that helps us process and analyze large amounts of data. It simplifies running big data frameworks like Hadoop and Spark on AWS for data processing and analysis. 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 for what we use. In this lesson, we will learn about the features of EMR and how it works.
