|'''instance''' | |'''instance''' | ||
| | | OpenStack virtual machines are called ''instances'', mostly because they are instances of an image that is created upon request and that is configured when the instance is launched. | ||

|'''[[Arbutus_Object_Storage|object storage]]''' | |'''[[Arbutus_Object_Storage|object storage]]''' | ||
| | | Object storage (or ''object-based storage'') is a storage type that manages data as objects, as opposed to other storage architectures like filesystems which manage data as a file hierarchy, and storage where data is managed as blocks. Each object typically includes the data itself, a variable amount of metadata, and a globally unique identifier. Offered as S3 and Swift protocols. Allocated in TB. See https://en.wikipedia.org/wiki/Object_storage. Currently only available with Arbutus. | ||
