Object storage runs on its own independent systems, which have their own redundancy and distribution. To ensure data consistency, sufficient time is needed for objects to fully replicate to all potential locations before being accessed. Object storage is optimized for high availability and will not be any less reliable than any other virtual machine within a cloud environment. It is hosted on a separate system that does not have dependencies in local host servers for access control, and it is optimized for files of all different sizes and uses.
