Cloud adoption continues to rise, and a multi-cloud strategy has become the de facto approach in 2019. According to the RightScale 2019 "State of the Cloud Report" from Flexera -- based on a survey of 786 technical executives, managers and practitioners -- 79% of all respondents run workloads in the cloud, and 94% use at least one public or private cloud. In addition, respondents are running applications in 3.4 clouds and experimenting with 1.5 more.

Meanwhile, the days of single cloud usage -- be it a public or private cloud -- have continued to wane, as a multi-cloud strategy has continued to garner a strong rate of adoption. In 2019, for example, 84% of respondents in organizations with more than 1,000 employees plan to use multiple clouds (up from 81% in 2018), and 58% intend to use a hybrid strategy (up 7 percentage points from the previous year's 51%).
