Real-world data backs up the conclusion that Docker is being widely adopted. DataDog, a cloud-monitoring system, found that by March 2016, “13.6 percent of Datadog’s customers had adopted Docker. One year later that number has grown to 18.8 percent. That’s almost 40 percent market-share growth in 12 months.” RightScale observed in its RightScale 2018 State of the Cloud report that Docker’s adoption by the industry has increased to 49 percent from 35 percent in 2017.
Docker, an open-source technology, isn’t just the darling of Linux powers such as Red Hat and Canonical. Proprietary software companies such as Oracle and Microsoft have also embraced Docker. Today, almost all IT and cloud companies have adopted Docker.
