Red Hat OpenStack Platform 12 Is Here!

We are happy to announce that Red Hat OpenStack Platform 12 is now Generally Available (GA).

This is Red Hat OpenStack Platform’s 10th release and is based on the upstream OpenStack release, Pike.

Red Hat OpenStack Platform 12 is focused on the operational aspects to deploying OpenStack. OpenStack has established itself as a solid technology choice and with this release, we are working hard to further improve the usability aspects and bring OpenStack and operators into harmony.

Enabling Keystone’s Fernet Tokens in Red Hat OpenStack Platform

As we learned in part one of this blog post, beginning with the OpenStack Kilo release, a new token provider is now available as an alternative to PKI and UUID. Fernet tokens are essentially an implementation of ephemeral tokens in Keystone. What this means is that tokens are no longer persisted and hence do not need to be replicated across clusters or regions.

“In short, OpenStack’s authentication and authorization metadata is neatly bundled into a MessagePacked payload, which is then encrypted and signed as a Fernet token. OpenStack Kilo’s implementation supports a three-phase key rotation model that requires zero downtime in a clustered environment.” (from: http://dolphm.com/openstack-keystone-fernet-tokens/)

An Introduction to Fernet tokens in Red Hat OpenStack Platform

Thank you for joining me to talk about Fernet tokens. In this first of three posts on Fernet tokens, I’d like to go over the definition of OpenStack tokens, the different types and why Fernet tokens should matter to you. This series will conclude with some awesome examples of how to use Red Hat Ansible to manage your Fernet token keys in production.

First, some definitions …

What is a token? OpenStack tokens are bearer tokens, used to authenticate and validate users and processes in your OpenStack environment. Pretty much any time anything happens in OpenStack a token is involved. The OpenStack Keystone service is the core service that issues and validates tokens. Using these tokens, users and and software clients via API’s authenticate, receive, and finally use that token when requesting operations ranging from creating compute resources to allocating storage. Services like Nova or Ceph then validate that token with Keystone and continue on with or deny the requested operation. The following diagram, shows a simplified version of this dance.

Hooroo! Australia bids farewell to incredible OpenStack Summit

We have reached the end of another successful and exciting OpenStack Summit. Sydney did not disappoint giving attendees a wonderful show of weather ranging from rain and wind to bright, brilliant sunshine. The running joke was that Sydney was, again, just trying to be like Melbourne. Most locals will get that joke, and hopefully now some of our international visitors do, too!

G’Day OpenStack!

In less than one week the OpenStack Summit is coming to Sydney! For those of us in the Australia/New Zealand (ANZ) region this is a very exciting time as we get to showcase our local OpenStack talents and successes. This summit will feature Australia’s largest banks, telcos, and enterprises and show the world how they have adopted, adapted, and succeeded with Open Source software and OpenStack.

Using Red Hat OpenStack Platform director to deploy co-located Ceph storage – Part One

An exciting new feature in Red Hat OpenStack Platform 11 is full Red Hat OpenStack Platform director support for deploying Red Hat Ceph storage directly on your overcloud compute nodes. Often called hyperconverged, or HCI (for Hyperconverged Infrastructure), this deployment model places the Red Hat Ceph Storage Object Storage Daemons (OSDs) and storage pools directly on the compute nodes.

Co-locating Red Hat Ceph Storage in this way can significantly reduce both the physical and financial footprint of your deployment without requiring any compromise on storage.
