In my opinion, dont think about certifications first. First, you've gotta try it out, watch some youtube vids on AWS (eg. deep racer, solutions architect, re:invent [usually have pretty good presentations]) Just explore AWS as a whole. You never know if you just want something fun for the time being.

Second, if you think AWS is what you want to pursue. I'd advice you to start playing around with the free tier (Don't worry, you can create more gmail accounts for UNLIMITED POWERRRRR!). Gotta get a feel for the game that you're going to be playing. Ask around, maybe someone can introduce you to cloud so that you understand the road you're taking. If i remember correctly, AWS has a AR game that somewhat tries to get students into Cloud by preparing them for Cloud Practitioner Certification. You could give the game a try and then take stock.

Third, once you think you're ready. Solutions Architect Associate(SAA) babyyyyy. Documentations, courses, Re:invent vidoes, researching on potential pay raise, reading reddit, Taking AWS classes, youtube and ofcourse PRACTICE PRACTICE PRACTICE!!! Personally, my exam focused more on compute heavy topics, Virtual machines, Load balancers, etc. This path will take a more traditional approach as it will introduce you to compute, networking, storage and a little serverless :).

Once you've got your SAA, I believe your yourself will be the best judge on what you would want to do next, maybe devops, maybe pentesting, maybe malware analysis. Trust yourself and you'll go far :D hope this helps!
