Containerization is a software deployment process that bundles an application’s code with all the files and libraries it needs to run on any infrastructure. Containerization does not include an underlying operating system that would require patching and management, as containers share the host operating system kernel and run in isolated user spaces. Containerization allows applications to run consistently and portably on any platform or cloud, regardless of the differences in operating systems, hardware, or configurations. Containerization also enables faster and easier deployment, scalability, and fault tolerance of applications. Therefore, containerization would best meet the need of a vendor who wants to distribute a cloud management application in a format that can be used on both public and private clouds.

The other options are not relevant to the question. Federation is a process of integrating multiple cloud services or providers to create a unified cloud environment. Collaboration is a process of working together on a shared project or goal using cloud-based tools and platforms. Microservices are a software architecture style that breaks down a complex application into smaller, independent, and loosely coupled services that communicate through APIs. Microservices can be implemented using containers, but they are not a software deployment format. Therefore, the correct answer is A. Containerization.
