Which template format is specifically created for compressing multiple files into one in FusionCompute?

The format specifically created for compressing multiple files into one in FusionCompute is recognized as the Open Virtualization Archive (OVA) format. OVA is a single-file format that encapsulates an entire virtual machine package, including the virtual machine configuration, disks, and additional descriptive files.

This consolidation into a single .ova file simplifies the distribution and deployment of virtual appliances because you are able to package everything together for easier transfer. OVA files use the TAR file format to bundle the contents, making it easier to manage virtual machines as single entities when moving between different environments or platforms.

While other formats mentioned, like OVF (Open Virtualization Format), are relevant in virtualization and contain important information about the virtual machine, they are primarily used to describe a virtual machine and are not as straightforward for compressing multiple files into a single format. Other formats, such as .vhd (which relates to virtual hard disks) and .zip (a general compression format), are not tailored specifically for the use case of virtual appliances in FusionCompute. Thus, the OVA format is the correct answer in this context.
