On a larger scale, tech giants are investing in DevOps as well. Just a few years ago, investors would have balked at developer-focused startups. But in 2018, the industry proved that it’s here to stay. Microsoft acquired GitHub, Google Cloud is snapping up a DevOps research firm, and now, with DevOps startups, developers want in. These startups range from ones that help companies release code faster, to those that help IT departments keep up.
