Thanks a lot for you answer. One more question, I log CB as maginatics user and I find out that the "/opt/maginatics/jclouds/bin/" directory has a program named "jclouds". And "jclouds" command includes blobstore blob-exists, blobstore blob-container-clear, group destory, node create, node list and so on. I want to know whether "jclouds group * " or "jclouds node * " or "jclouds image * " or "jclouds location list " is used to communicate with cloud storage ?

jcloud command:

maginatics@cloudboost1:/opt/maginatics/jclouds-cli/bin$ ./jclouds

Command not found: Usage: jclouds {category} {action} {options/arguments}

Valid commands:

    blobstore blob-exists

    blobstore blob-metadata

    blobstore container-clear

    blobstore container-create

    blobstore container-delete

    blobstore container-exists

    blobstore container-list

    blobstore container-metadata

    blobstore list

    blobstore location-list

    blobstore read

    blobstore remove

    blobstore write

    group destroy

    group runscript

    hardware list

    image create

    image list

    location list

    node create

    node destroy

    node destroy-all

    node info

    node list

    node resume

    node runscript

    node suspend

Options:

    --properties: File containing properties

    --provider:   The id of the provider

    --api:        The id of the api

    --endpoint:   The endpoint

    --identity:   The identity

    --credential: The credential

jclouds is an open source multi-cloud toolkit that has many other features. CloudBoost only uses the subset related to object storage.

So, does CloudBoost only use "./jclouds blobstore * " command to communicate with object storage ?

That is correct only the blobstore commands are used. CloudBoost does not create any compute resources in the cloud.

OK ,Thank you so much.
