The cloud has been a disruptive force that has touched every industry in the last decade. Not all cloud technology is the same, though. There are cloud-native technologies like serverless and cloud-legacy technologies like relational databases, which were first proposed in 1970. One easy way to note this distinction is to think about the cloud as the new operating system. Before there was the cloud, you had to write your application for Windows, Mac or some Unix/Linux flavor. After the cloud, you could either port your legacy application and legacy technologies, or you could design your application natively for the cloud.
