The technology that provides an interface for defining and linking the services of the cloud is known as API (Application Programming Interface). APIs allow developers to create applications that can seamlessly interact with cloud services and resources. They enable the integration of various functionalities, facilitating communication between different software components. Through APIs, developers can request and manipulate data, leading to greater flexibility and scalability in deploying cloud applications. Using well-defined APIs also contributes to the interoperability of systems, ensuring that different cloud services can work together effectively in a unified ecosystem.
