According to Gartner’s Andrew Lerner, many of the networking practitioners running mainstream corporate networks have only surface-level knowledge of OpenStack as evidenced in his recent blog. To assist networkers to understand Openstack, we created an easy white-board style video illustration of OpenStack for beginners with specific use-cases, featuring networking in a Cisco ACI context. Lucien Avramov from Cisco’s Insieme Business Unit, a lead Technical Marketing Engineer and an OpenStack evangelist gleefully signed up to do the Videos. In this blog, I am pleased to present highlights of the videos.
Lucien rightfully starts his white-board Videos with one that discusses the basics, namely “What is OpenStack and Networking”.
This video covers OpenStack and Networking. Lucien does a deep-dive into the Neutron project and explains Neutron basics and its interaction with the physical and virtual networks of a Data Center.

The last video covers the benefits of ACI with OpenStack. In this Video Lucien describes the workflow between ACI and OpenStack. You will learn the benefits of ACI with OpenStack including the ACI policy model, physical and virtual environment integration, hardware tunnels, service chaining and telemetry such as health scores, troubleshooting and visibility.
Cisco highlighted its support for OpenStack at the recent OpenStack Summit in Atlanta, which hosted 4500+ attendees and included many more users, in addition to the developers and operators that have dominated past conferences. A common theme among keynote presentations was the speed and flexibility of IT required to support the clouds that will soon dominate commerce and communication worldwide. The effort underway to improve stability was also a recurring discussion topic.
OpenStack Summit, May 12-15 in Atlanta
From its beginning as an open source project at NASA, the OpenStack movement has grown as an open alternative to propriety cloud services and applications. The Summit serves as a forum for those interested in hashing out the direction and adoption of the model and standards, as well as a learning opportunity for those ready to build and deploy on them.
Keynote speakers from Wells Fargo and Disney helped transition the Summit from an academic exercise to a forum for learning how innovative companies are taking control of their cloud environments.
Glenn Ferguson, Head of Private Cloud Enablement for Wells Fargo, described the compliance, auditing and governance Wells requires in its private cloud, that aren’t available in public cloud offerings. Wells has designated OpenStack their “cloud infrastructure model” to facilitate rapid deployment of infrastructure to meet application developers’ needs and requires all IT vendors to work within the OpenStack specifications. “This is something we have to do to remain agile and competitive in this environment,” Ferguson said. “Our infrastructure needs to keep pace with the software.”
Chris Launey, Disney’s Director of Cloud Architectures and Services, was blunt in how he described the value of speed. “If you’re a business that deals in any kind of information, you need speed (to thrive.) “If you give (developers) their own ‘fast’, they’ll make their own ‘cheap’ by getting their product to market quickly and responding to customer demands. And (they’ll) make their own ‘good’ by shrinking development cycles and introducing improvements more often, until they reach a virtual continuous cycle of improvements.”
The OpenStack Foundation divides the work into individual projects focused on the various cloud components: servers, object-based storage, networking infrastructure, security, etc. Proponents are excited about the innovation that can be unleashed when developers are freed from having to worry about the complexities associated with underlying infrastructure and can focus on the innovation of cloud services and applications.
Cisco was highly visible at the Summit, drawing standing-room-only crowds to sessions in the Networking Track, as network stability and scalability are top-of-mind for users deploying critical applications and services to an open source cloud.
Lew Tucker, Cisco Vice President and CTO for Cloud Computing and Vice-Chair of the OpenStack Foundation, painted a picture of what is possible in his presentation “Open Stack and the Transformation of the Data Center.” He described how the data center is becoming a large, highly automated “fabric” consisting of interconnected physical systems and virtualized services. In this environment, OpenStack acts as a platform for building a highly efficient cloud, providing management of diverse infrastructure “below” and orchestration of a vast set of application services “above”.

Cisco’s key contribution to OpenStack has been participation in the development of Neutron, the OpenStack Networking Service. There is clearly a need to have the same level of visibility and management flexibility that Cisco has been offering its customers in an open source cloud model. In addition to driving connectivity generally, Cisco has received approval on blueprints for plugins to integrate VPN- and Firewall-as-a-Service as part of OpenStack networking. (Referred to as Network Function Virtualization (NFV) plugins.) Cisco is also working on the integration of OpenStack Neutron with OpenDaylight, a separate project started to focus specifically on network programmability. Cisco’s extensive work in the open source community will bring even greater value to its existing customers by extending the ecosystem of solutions integrated with Cisco products.
In the Expo Hall, Cisco highlighted the integration of its networking, compute and management products with OpenStack APIs, demonstrating:
This week has been the semi-annual OpenStack Summit in Atlanta, GA. In a rare occurrence I’ve been able to be here as an attendee, which has given me wide insight into a world of Open Source development I rarely get to see outside of some interpersonal conversations with DevOps people. (If you’re not sure what OpenStack is, or what the difference is between it and OpenFlow, OpenDaylight, etc., you may want to read an earlier blog I wrote that explains it in plain English).
On the first day of the conference there was an “Ask the Experts” session based upon storage. Since i’ve been trying to work my way into this world of Programmability via my experience with storage and storage networking, I figured it would be an excellent place to start. Also, it was the first session of the conference.
During the course of the Q&A, John Griffith, the Program Technical Lead (PTL) of the Cinder project (Cinder is the name of the core project within OpenStack that deals with block storage) happened to mention that he believed that Cinder represented software-defined storage as a practical application of the concept.
I’m afraid I have to respectfully disagree. At least, I would hesitate to give it that kind of association yet. Read More »
