What characteristics of cloud computing are described by the ability to move virtual machine files between hosts?

The ability to move virtual machine files between hosts is best characterized by partition and independence. Partition refers to the separation of resources in a cloud environment, allowing different virtual machines to run on different physical hosts without interference. This separation ensures that each virtual machine operates independently, leading to efficient resource management and load balancing across various hosts.

Independence emphasizes that virtual machines can function on various hardware setups without being tied to a specific physical server. This capability allows for seamless migrations of virtual machines, which can enhance overall system performance, facilitate maintenance, and support dynamic resource allocation as workloads change.

The other characteristics, such as scalability and redundancy, relate to how resources can be increased or duplicated respectively, but do not specifically focus on the aspect of moving virtual machines. Isolation and encapsulation speak to security and process separation but do not encompass the mobility of virtual machines. Flexibility and performance address the general adaptability of cloud infrastructure but do not directly explain the mechanism of transferring virtual machine files between hosts, which is fundamentally tied to partition and independence.
