AWS certifications are split into nine sub-groups. Big Data is one of the vendor’s three Specialty certifications—the others being Advanced Networking, and Security. As the name suggests, this badge covers all things related to big data analysis on AWS, and is aimed at professionals who’re responsible for running intricate Big Data analysis. Broadly, the certification validates your ability to implement AWS Big Data services, design and maintain Big Data infrastructure, and take advantage of AWS tools to automate parts of the analytical process. The exam is a multiple-choice, multiple-answer test, and you have 170 minutes to complete it. The AWS Certified Big Data – Specialty certification needs to be renewed every three years. With effect from April 2020, this certification shall be called as AWS Certified Data Analytics – Specialty.
