AWS Certified Data Analytics Specialty 2021 - Hands-On! - Section Introduction: Processing

This video tutorial covers the AWS Certified Big Data Specialty exam's processing domain. It begins with AWS Lambda's role in connecting services for big data movement, followed by AWS Glue's ability to structure unstructured data in an S3 data lake. The tutorial then delves into Elastic MapReduce, a managed Hadoop cluster for processing large datasets, and explores various tools like Apache Spark and Hive. It also introduces AWS machine learning services, including SageMaker, and discusses the AWS Data Pipeline for creating processing workflows. The video concludes with hands-on activities, including building a product recommendation system and predicting order quantities.
