Provide a significant portion of the funding to achieve the Foundation's mission of protecting, empowering and promoting the OpenStack community and software. Each Platinum Member's company strategy aligns with the OpenStack mission and is responsible for committing full-time resources toward the project. There are eight Platinum Members at any given time, each of which holds a seat on the Board of Directors.

• AT&T
• Canonical
• Hewlett Packard Enterprise
• IBM
• Intel
• Rackspace
• Red Hat, Inc.
• SUSE

Provide funding and pledge strategic alignment to the OpenStack mission. There can be up to twenty-four Gold Members at any given time, subject to board approval.

• images registry: Download images, like Ubuntu, CentOS,Sahara Apache Spark 1.0.0,etc.

Upload image uses glance may be very slow as using http transmission. If use ceph rbd backend storage, we can speed up via rbd import command:

upload()

        if [[ -z $IMAGE_PATH ]]; then
                echo "Usage: $0 <IMAGE>"
