If you're writing about RDO, or about OpenStack on CentOS, Fedora or RHEL, and you're not on my list, please let me know!

OpenContrail on the controller side by Sylvain Afchain

In my previous post I explained how packets are forwarded from point to point within OpenContrail. We saw the tools available to check what are the routes involved in the forwarding. Last time we focused on the agent side but now we are going to understand on another key component: the controller..

Highly available virtual machines in RHEL OpenStack Platform 7 by Steve Gordon

OpenStack provides scale and redundancy at the infrastructure layer to provide high availability for applications built for operation in a horizontally scaling cloud computing environment. It has been designed for applications that are “designed for failure” and voluntarily excluded features that would enable traditional enterprise applications, in fear of limiting its’ scalability and corrupting its initial goals. These traditional enterprise applications demand continuous operation, and fast, automatic recovery in the event of an infrastructure level failure. While an increasing number of enterprises look to OpenStack as providing the infrastructure platform for their forward-looking applications they are also looking to simplify operations by consolidating their legacy application workloads on it as well.

Virtualization has been a key technology for making this kind of work possible. OpenStack is great of managing virtualization. Added to that is the benefits found when one “Fly our own airplanes.” Thus, I am using OpenStack to develop OpenStack.
