How do go about learning more about the cloud?

I'm a recent graduate of an A.A.S degree in IT focusing on networking. I'm currently trying to find a job and I was just casually browsing through this subreddit and I saw a lot of people saying to learn more about the cloud.

I have a huge interest in cloud technology, especially since I.a.a.S is becoming a bigger industry, but I have no idea on how to start learning about this stuff that would make me desirable for an employer.

Any advice on where to start and what to learn? I'm also not afraid of programming.
