I think the approach can be applied to many companies. I have seen some companies turning every single data storing problem into an Oracle problem. Amazon turned many of the problems into ones that are easier to solve. Using 6 different technologies[1]. I am sure not all applies to all departments but it is a better approach to do this at the scale they got. For small companies this really does not matter. If your hot data fits a single node disk cache you obviously won't benefit from using a horizontally scalable database but Oracle's customers are often in the higher end of the scale spectrum. The question is how can Amazon compete with Oracle where the relationship is there for decades between a customer and Oracle. Good example of this is banks. They managed to get some of the financial companies to move some workloads to AWS but to move Oracle workloads to something else is a whole different game. 1. https://media.amazonwebservices.com/blog/2019/bye_bye_oracle_1.png https://media.amazonwebservices.com/blog/2019/bye_bye_oracle...
