Cisco Champion Radio on ACI and Nexus 9000

March 3, 2014 at 11:07 am PST
  • How ACI lets you manage a network cohesively instead of box-by-box ?
  • What a network looks like in ACI mode vs. stand-alone mode ?
  • How ACI works with network protocols like spanning-tree and TRILL ?
  • Upgrading the Nexus 9000 Series to ACI
  • When does ACI make sense for your business ?

For this new episode of the podcast with Cisco Champion, we are fortunate to have a great technical (and casual) dialog between two active members of the data center and cloud social media sphere.

LynchOnisick2

Colin Lynch (@UCSguru) based in London is a subject matter expert for Cisco UCS, Integrated Systems, Converged Infrastructure and writes also on SDN . Colin has an independant blog at UCSguru.com He was nominated ComputaCenter Consultant of the Year in 2013 .

Colin talked with Joe Onisick (@jonisick) who works for Insieme Networks, now part of Cisco. Joe writes an independant blog at DefineTheCloud.com. He talked about ACI in multiple videos and podcasts.

After attending Cisco Live Europe in Milan, Colin was at VMware PEX to have an in-depth analysis of NSX , and wanted to “challenge ” Joe on several points, which makes this conversation even more lively !

I found this dialog extremely rich, as both participants were willing to address difficult and controversial aspects of the Data Center architecture today and tomorrow,  for instance around layer 2 and layer 3,  network programmability and management, or the future of networking certification ! You will also better understand, why Cisco is heavily investing in ACI solutions, when at the same type keeps developing other paths .
A very exciting 40 mn conversation between two great subject matter experts, really passionate by this topic, spiced  with additional questions from other Cisco Champions and…humor.

Listen now to our guests and enjoy the show hosted by @commsninja.

I also encourage you to read this very didactic explanation from Tom Edsall, Cisco Fellow and CTO of Insieme Networks, in this new blog from Shashi Kiran
ACI Design Principles : The Role of SDN Overlays in Application Centric Deployement . Shashi  will publish the second part tomorrow .

As a reminder, Cisco Champion is a community of  technical professionals who are passionate about sharing their knowledge and expertise. They are ready to offer their time to help others to learn about Cisco and connect with Cisco in unique way
For Data Center and Cloud , we have now more than 40 members, who have been nominated by peers for one year . We invite them to give their opinion on market trends, Cisco solutions and products . We encourage also them to participate to our Cisco Live events , webcasts, podcasts , Google + HOA , blogs and tweet to share their experience and wisdom.

Network Programmability Is Real: Five Use Cases for Our Disaster Recovery Cloud Services

SunGard AS has more than 9000 enterprise customers who count on our cloud services and managed services when disaster strikes. Lately, we’ve seen that the “Internet of Everything” is changing customer expectations. Our customers want new types of cloud services—and they want them sooner. They’re also asking to provision and control the services on their own. To keep delivering new products and services, we need a network that’s more flexible, intelligent, secure, and agile than ever before.

Our strategy for the future is to create a platform for service agility by enabling network programming. This is a radical change for our business and our customers. Not having to wait for engineers to program the network will help us bring new services to market sooner. Network programmability will also make it possible to offer new self-service options our customers are requesting, like bandwidth calendaring and service on demand. Read More »

CiscoLive Milan Highlights: IoE, SDN and a lot of wine

Aside from an ill-timed Milanese taxi strike and a lot of rain and snow, the first CiscoLive of 2014 was a fascinating week. Cisco EVP Rob Lloyd announced our latest Cisco ONE capabilities with a new APIC Enterprise module and the new Inter Cloud capability for moving workload (virtual machines) between private and public clouds.  Both of these announcements underscore Cisco’s expansion into software-defined infrastructure. Now IT administrators can centrally apply policies across data center, WAN and access networks and transparently move workloads and apps across private and public clouds. Now, that’s agility. That’s lower operational costs.

My App anywhere: On devices, on controller, on both!

January 29, 2014 at 12:41 am PST

Current differences in app development on devices and controllers disappear. Devices and controllers will share a common programming environment – offering a unified development and deployment experience.

While SDN is moving from concept to reality, we notice that many deployments which focus on creating new network features interpret the role of the “controller” very pragmatically. In these deployments, the controller is not used as an independent layer of software which abstracts the entire underlying infrastructure as in the traditional view of SDN (see for example ONF’s SDN Definition). The pragmatic approach to network programming simply extends the distributed development environment of the network devices using a set of qualities offered by the controller.  Developers move those components of their distributed apps to the controller that benefit from the logical centralization or the enhanced resources (CPU, memory) that a controller typically offers while keeping other components on the network devices. Example use cases fall into the categories of distributed network analytics, DDoS thread mitigation, or routing optimization based on performance measurements. What does this mean for our development environment?
