As SDN technologies become more mainstream, it is imperative to replicate the success of DevOps techniques from the IT world to bridge the gap that few envisioned in the first place –between the Application/Service and the Network layer. This presentation made in the DevNet Zone at Cisco Live, San Francisco, 2014.

Can we help tie the workflows? – We need an enabler!
• An Easy to use, automated environment to code in
• A platform to leverage the ecosystem and refactor existing
apps
• A Complete continuous integration suite to test my apps
• One environment to work with all the Network programmability
technologies – Device APIs, Controllers, containers, DevOps tools..
• A simulation environment to ensure high fidelity on deployment
• Test results that can be trusted in the real world
• Packaging tools for code deployment
