An application is considered cloud-based when it has been subsequently adapted for operation in the cloud. In other words, it already existed and was not “born in the cloud” (i.e., it is not cloud-native). Instead, it was adapted and optimized for the cloud.
Companies reduce effort with the cloud-based approach: it enables them to use cloud platforms and dynamic cloud infrastructures without having to redevelop the application from scratch. In addition, there is no need for the company’s internal IT to procure and maintain hardware. Instead, companies rent IT resources from a cloud provider as needed. This eliminates the need for long-term investments in IT infrastructure. Moreover, the flexible on-demand model in the cloud provides companies with rapid scalability. This allows them to quickly increase the availability of their application when demand peaks.
