I'm new to openstack, now reading some documentation. I have question about the object storage.

Could the swift object storage be used by apps running on virtual machine? I guess the answer should be YES. If so, do apps also use the Openstack HTTP based API to operate the storage? I'm afraid the performance issue.

Can you provide more details about the particular performance issues that you are worried about? Making requests against swift just involved HTTP calls, so it should not be compute-intensive, so CPU performance shouldn't be an issue. Are you worried about network performance of moving lots of data in and out of a VM? – Lorin Hochstein Dec 9 '12 at 21:13

Yep. You can. All external apps interact with OpenStack services via their HTTP API.

Probably the easiest way to interact with Swift is via the python-swiftclient. See

If you're using PHP, you might want to consider php-opencloud. See

If you're using Java, you might want to consider jclouds. See

If you're concerned about performance, I'd suggest doing some performance testing to see if they'll meet your needs.
