Simple Object Access Protocol (SOAP) encapsulates its information in what is known as a SOAP envelope. It then leverages common communications protocols for transmission. Object is a type of cloud storage, but also a commonly used term with certain types of programming languages. Packet and payload are terms that sound similar to envelope but are not correct in this case.
