Cloud environments are based entirely on virtual machines and virtual devices, and those images are also in need of storage within the environment. What type of storage is typically used for virtual i

Volume storage (block storage) is typically used for operating system disks and application data requiring high performance, not for collections of virtual images themselves.

Structured storage refers to data organized in a defined schema (e.g., databases), which is not the primary way virtual machine images are stored.

Unstructured storage is a broad category, but object storage is the specific and most appropriate type for virtual images within that category.

Object storage, such as AWS S3 or Azure Blob storage, is highly scalable and durable, making it ideal for storing large numbers of immutable virtual machine images, container images, and snapshots due to its cost-effectiveness and accessibility characteristics.
