Description Access Hide differences in data representation and how an object is accessed Location Hide where an object is located Relocation Hide that an object may be moved to another location while in use Migration Hide that an object may move to another location Replication Hide that an object is replicated Concurrency Hide that an object may be shared by several independent users Failure Hide the failure and recovery of an object Note Distribution transparency is a nice a goal, but achieving it is a different story.
Which operations do we allow downloaded code to perform? Which QoS requirements do we adjust in the face of varying bandwidth? What level of secrecy do we require for communication?
The non solution: powerful servers. Today, the challenge lies in geographical and administrative scalability. Always keeping copies consistent and in a general way requires global synchronization on each modification. Global synchronization precludes large-scale solutions. Observation If we can tolerate inconsistencies, we may reduce the need for global synchronization, but tolerating inconsistencies is application dependent. In essence, this is a grouping of users or better: their IDs that will allow for authorization on resource allocation.
Customers normally never get to see these. Infrastructure: Deploys virtualization techniques. Evolves around allocating and managing virtual storage devices and virtual servers.
Platform: Provides higher-level abstractions for storage and such. Example: Amazon S3 storage system offers an API for locally created files to be organized and stored in so-called buckets.
