COSBench is a benchmarking tool to measure the performance of Cloud Object
Storage services. Object storage is an emerging technology that is different
from traditional file systems (e.g., NFS) or block device systems (e.g.,
iSCSI). Amazon S3 and Openstack* swift are well-known object storage solutions.

COSBench now supports OpenStack* Swift, Amazon* S3, Amplidata v2.3, 2.5 and
3.1, Scality, Ceph, CDMI, Google Cloud Storage, as well as custom adaptors.
