More Security and Flexibility in Rackspace Private Cloud Powered by Red Hat

Version 10 of Rackspace Private Cloud Powered by Red Hat is now generally available, building on the partnership between Rackspace and Red Hat to extend the capabilities and usability of the Red Hat OpenStack platform as a fully managed service, operated by Rackspace.

As enterprises continue to evaluate OpenStack as a private cloud solution, their traditional but very relevant concerns include stability, flexibility and security. Specifically, enterprises want to know they can use OpenStack to provide their users with a platform for running diverse workloads, according to the needs of the business, without compromising security in any way.

Understanding the importance of these concerns, Rackspace and Red Hat have continued to innovate our jointly managed OpenStack offering. After our initial success in 2016, we have been moving full speed ahead, in conjunction with the OpenStack community to deliver new capabilities to answer stability, flexibility and security concerns.

This latest version packages a fully engineered and managed version of Newton, the most recent version of OpenStack from the open source project of the same name. As with previous versions, the community has put in a great deal of work stabilizing the platform and patching bugs in the code. Red Hat and Rackspace build on the work of the community to curate and to deliver the most stable and hardened version of OpenStack possible.


  • Ironic for bare metal – Historically, OpenStack has enabled self-service provisioning of virtual instances, which has satisfied the majority of uses cases. However, many users are also looking for the flexibility of being able to run workloads on single tenant bare-metal servers and doing so on demand through self-service provisioning. The use case for bare-metal instances range from big data Hadoop workloads to containers where users want to avoid the overhead of virtualization.

Previous versions of Red Hat OpenStack platform and Rackspace Private Cloud Powered by Red Hat supported Ironic, the OpenStack bare-metal provisioning project, for deploying the overcloud control plane but not for tenant usage. With version 10, Ironic has reached a level of maturity that allows customers to take full advantage of the performance of bare metal instances while retaining the elasticity and agility of virtual instances.

  • Composable roles – The reference architecture for version 10 calls for multiple nodes with each node running a set of services defined via five specifically assigned TripleO roles:  Controller, Compute, BlockStorage, CephStorage and ObjectStorage. Using the Director node, users now have the flexibility to assign these set roles as well as assign user-defined custom roles in different combinations across their cloud. This will enable users to adapt their cloud quickly to meet changing needs.


Security is of paramount importance for enterprise customers as they evaluate private cloud solutions. This is also the area of biggest advancement in version 10 of Rackspace Private Cloud powered by Red Hat, particularly with the Keystone project. Considerable work has been done to enable users to deploy cloud resources with more security options than ever before. Newly supported capabilities include:

  • Domain-specific roles – This capability gives cloud administrators finer grain control over how user permissions are assigned. Users can be granted specific rights to a domain or collection of projects and simultaneously be granted different rights to an individual project.
  • Multi-domain LDAP support – allows users to take advantage of multiple LDAP compatible back-ends for user authentication.
  • Fernet token – Fernet token support makes user authentication more scalable, efficient and performant by minimizing the amount identity information that is required to be transferred with each user session.

Version 10 of Rackspace Private Cloud powered by Red Hat is a major milestone for the Rackspace and Red Hat partnership and advances our joint commitment to providing our customers the best managed private cloud solution in the market.
