One way to best ways stay abreast of the latest DevOps developments is to focus on what the leaders in the field are talking about on social media, and there's no better way to do that than to follow TechBeacon's DevOps 100 list.

This year's crop of leaders includes nearly 60 new names, as well as additional information about the folks who also made last year's list. Our list is based on input from IT Revolution and its DevOps Enterprise Summit programming committee.

DevOps 100 is organized into categories, from noted authors and next-generation operations to value-stream mapping, so you can quickly find the experts you most want to follow. Those pros speaking at the annual DevOps Enterprise Summit Las Vegas - Virtual this year, or who spoke at DevOps Enterprise Summit - London earlier this year, are noted with asterisks (**).
