Platform sharing refers to the practice where multiple companies or services utilize the same underlying technology or infrastructure to deliver their products. This approach allows businesses to reduce costs, increase efficiency, and enhance collaboration. For example, various apps can operate on the same operating system, like Android or iOS, benefiting from shared resources. In addition to cost savings, platform sharing can foster innovation by allowing developers to build on existing frameworks. This can lead to a diverse range of applications and services that enhance user experience. A well-known example is Amazon Web Services, which provides cloud computing resources to numerous businesses, enabling them to scale efficiently.
