DevOps 100: Top leaders, practitioners, experts to follow

If you're not following veterans and newcomers in the DevOps community, you're not seeing the whole picture and staying ahead of the curve. Almost three years ago, TechBeacon compiled a list of the top 100 DevOps leaders, practitioners, and experts to follow on social media. Since then, many new luminaries and new topics have emerged, and the article was in need of an update.

Here is a hand-picked list of 100 exceptional writers, speakers, and leaders who can teach you a great deal about DevOps. The list is organized into sub-topics: general DevOps, cloud, containers, serverless, monitoring, systems engineering, agile, and testing.
