There has been an issue about who is Cloud engineer, DevOps engineer or even SRE. What is your opinion about these roles and what technical tasks do they do that are different from one another at GitHub?
Titles evolve as we go, and I've seen both folks doing the same job while having different titles, and folks with the same title doing very different jobs. If you are looking into acquiring skills in these areas, I would look at job descriptions with similar titles from a few companies that you would like to work for, and develop my learning plan based on the common denominators of these job descriptions.
