Yesterday I took and passed the AWS certified cloud practitioner exam.
For the past 2.5-3 months, I studied pretty hard for this exam. It's listed as "Entry Level" but without any previous AWS experience, I found it fairly challenging. It's a great stepping stone for someone who is trying to get their feet wet in AWS and the certifications they offer.
Amazon offers free video training and white papers that are made for the exam. In addition to those resources, I used some practice exams from Udemy and ACloud.Guru.
From here I'm going to go after the AWS Solutions Architect.
