Lippis Report 223: An Open Approach to Network Automation

March 3rd, 2015

nick_podium2Modern day networking is labor intensive. Configuration, monitoring and change management are manual processes for the most part. In fact, at the last Open Networking User Group (ONUG) this past Fall at Credit Suisse, most IT business leaders said that one network engineer supports approximately 120 networking devices such as a router, switch, etc. Compare this to 20,000 servers that a single engineer manages at a hyper scale firm and you can see that networking needs automation. Manual networks are not helping IT business leaders who are feeling pressure from business unit managers demanding self-service IT delivery on par with cloud providers such as Amazon, Azure, etc., but without the implied loss of security, visibility and control. Case in point: at ONUG in Boston hosted by Fidelity Investments, large financial service firms showed what happens when they offer business unit managers on-demand virtual machine (VM) creation and deletion; the trend lines showed exponential growth, demand and consumption!

Policy-Driven Infrastructure: Separating User Intent from Configuration Procedures

Listen to the Podcast

January 28th, 2015

policy_driven_infrastructure_mike_sandeepThe focus on separating user intent from infrastructure is an important new insight into how cloud environments should be run.  To drive forward this approach, Group-Based Policy is currently being developed for both OpenStack and OpenDaylight open source projects. Mike Cohen, Director of Product Management and Sandeep Agrawal Senior Marketing Manager, both of whom work at Cisco Systems join me to talk about Group-Based Policy or using intent to manage infrastructure.

Question 7 @ 12:20 sec: Mike, Does GBP assist in the creation of an application dependency map that can be shared across multiple IT teams, such as storage, networking, servers/virtualization and application development?

 

Question 8 @ 13:41 sec: Mike, How are the policies that are created configured within the products that make up the infrastructure?

 

Question 9 @ 15:09 sec: Mike, GBP is being adopted by OpenStack and OpenDayLight, but how will it be implemented by the vendor community within products?

 

Question 10 @ 18:03 sec: Mike, How does GBP compare to other efforts such as:  Congress and ONOS?
