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.

The primary purpose of the gap analysis is to begin the benchmarking process against risk and security standards and frameworks.

Explanation
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.
