OpenStack Juno


Since block storage or a virtual disk in a different location could be attached to a VM, getting full console access to help an administrator rescue a failed server can be a complicated process, Bryce said. In Nova, as part of OpenStack Juno, that process has been simplified and improved with the new rescue mode.

"So a user can now go into rescue mode and check for disk corruptions and make sure that a reboot won't wipe out important data somewhere," Bryce explained. "It also allows an administrator to boot into any arbitrary image, including a Linux rescue disk or data recovery tool to manage a virtual machine that has some kind of problem."

Keystone Identity

The OpenStack Keystone project, which provides access and identity features, has been enhanced in the Juno release with improved multi-cloud federation features.

"The OpenStack Icehouse release had the first round of basic multi-cloud federation capabilities, but it was limited to very specific use-cases," Bryce explained. "What the OpenStack Juno release brings is support for standard federation protocols, including SAML [Security Assertion Markup Language]."

At the OpenStack Summit in Atlanta in May of this year, Troy Toman, cloud architect at Rackspace, delivered a keynote speech in which he postulated that OpenStack could become a planetary-scale cloud operating system. Having multi-cloud federation capabilities is a primary enabler of the planetary-scale idea.

"I won't say that we have reached the nirvana state of a planetary-scale operating system," Bryce said. "But it is now certainly possible to connect various OpenStack environments to each other and use a single access credential."
