In 2016, cloud computing started to dominate many IT market segments. As a business, Synergy Research Group reported that industry revenue for the four quarters ended Sept. 30 grew 25%. Operator and vendor revenue for six segments of cloud computing reached $148 billion during that period, with spending on private clouds accounting for over half the total but spending on the public cloud growing much more rapidly. As more and more companies are taking advantage of the benefits of moving to cloud services, there is a significant need for IT professionals to gain the skills needed to successfully use and implement a wide range of cloud services, making typical vendor-focused training solutions less valuable.
