To become an AWS Big data professional, AWS Big Data Specialty Certification is very important. These certifications validate the knowledge of an individual in executing the AWS Big data analytics services as per the architecture practices. If you are preparing for the AWS Big Data specialty certification exam, I recommend this AWS Big data Training course by Intellipaat. To take this course, a little bit of knowledge in Big data and working of AWS to implement Big Data on the cloud would be better.
