The answer is C. REST.
REST, or Representational State Transfer, is an architectural style for building distributed systems. It uses HTTP messages to transfer data between applications residing on different hosts. RESTful APIs rely on the HTTP protocol to send and receive data. This means that applications can communicate with each other over the internet using standard HTTP methods, such as GET, POST, PUT, and DELETE.
HTTP is a widely used protocol for transmitting data over the internet. It is the foundation of the World Wide Web and allows for the transfer of text, images, audio, video, and other types of data. RESTful APIs use HTTP to transfer data in a format that can be easily understood by both the sender and receiver.
OpenStack is a set of open-source software tools for building and managing cloud computing platforms. OpFlex is a protocol used in Cisco's Application Centric Infrastructure (ACI) for communicating between the ACI fabric and network devices. OpenFlow is a protocol used in software-defined networking (SDN) for controlling the flow of network traffic. While each of these technologies may use HTTP as a transport protocol, they do not use it exclusively for transferring data between applications on different hosts.
