DevOps is a process (e.g. a bunch of key practices) that helps teams take software they’ve built and make sure it works well at scale.
Building software is only part of the battle - you need to distribute it to your customers, and it needs to work for them, all the time. Mass adoption of the cloud has moved software to the web and scaled it by a lot, which makes actually running that software kinda hard.
DevOps can be a team, but it’s mostly a process that centers around 4 big things: pre-release building, CI/CD, infrastructure, and monitoring. But in a nutshell, basically DevOps teams worry about making sure your app works for anyone who wants to use it.
