" which take cares of marshaling and un-marshaling of messages into function "
"calls. Each Nova service, such as Compute, Scheduler, and so on, creates two"
" queues at the initialization time, one which accepts messages with routing "
"keys ‘NODE-TYPE.NODE-ID’, for example, compute.hostname, and another, which "

" can kill the instance. The API acts as a consumer when RPC calls are "

"OpenStack Object Storage (code-named Swift) is open source software for "
"creating redundant, scalable data storage using clusters of standardized "
"servers to store petabytes of accessible data. It is a long-term storage "
"system for large amounts of static data that can be retrieved, leveraged, "
"and updated. Object Storage uses a distributed architecture with no central "
"point of control, providing greater scalability, redundancy and permanence. "
"Objects are written to multiple hardware devices, with the OpenStack "
"software responsible for ensuring data replication and integrity across the "
"cluster. Storage clusters scale horizontally by adding new nodes. Should a "
"node fail, OpenStack works to replicate its content from other active nodes."
" Because OpenStack uses software logic to ensure data replication and "
