I would recommend Intellipaat as the best website for AWS and DevOps training. Because many training partners offer paid online courses on AWS DevOps, it becomes difficult to choose one from many available out there. I would say check out the entire course, its curriculum, live sessions, doubt clearing sessions, instructors' experience, projects, and assignments.
If you are satisfied with the course offerings, then choose that particular training partner. I would support my recommendation with a customer feedback video that you will find to be more insightful. Intellipaat offers you AWS DevOps Training.
