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.



Duration: 21 minutes 17 seconds


Lippis Intro/Analysis @ : 00:10 sec


Question 1 @ 2:44 sec: Sandeep, What is GBP and what problem is trying to solve.


Question 2 @ 4:28 sec: Mike, What are the architectural components associated with GBP?


Question 3 @ 5:41 sec: Sandeep, How does GBP contribute to an open SDN approach?


Question 4 @ 6:48 sec: Sandeep, What does GBP mean for security and governance?


Question 5 @ 8:51 sec: Mike, Does GBP offer a means to automate network configuration and change management? 


Question 6 @ 10:23 sec: Mike, One part of GBP is that it gathers the state of the infrastructure.  How does it accomplish this, is there a state database that’s created?


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?

Attend ONUG Academy and Increase Your Value in the Networking Job Market

Watch the Video

September 23rd, 2013

AttendONUGAcademy_NickGraphicThere is a fundamental shift occurring in network engineering skill set requirements as open networking and Software-Defined Networking technologies continue their rapid deployments. DevOps will have a larger role in network purchases. New network designs are emerging, thanks to virtual overlays, white box networking, Linux-based network-programming tools, OpenFlow based pSwitches and vSwitches, etc. The CCIE skills set is being augmented with SDN skills and know-how. To keep competitive and relevant in the networking industry job market, you need SDN skills. ONUG Academy offers five tutorials taught by the experts who are deploying and developing open networking/SDN standards plus technology, including:

T1: Understanding and Deploying Virtual Networks by: Srini Seetharaman, Technical Lead for SDN at Deutsche Telecom

T2: Getting Started with OpenFlow Deployments by: Brent Salisbury, University of Kentucky

T3: Integrating OpenFlow and OpenStack by: Rob Sherwood, Open Networking Foundation Chair of Architecture and Framework Working Group

T4: Understanding White Box Networking Architecture and Economics by: JR Rivers, Co-Founder and CEO of Cumulus Networks

T5: Writing SDN Applications on Popular Controllers by: Matt Davy and Chuck Black, Tallac Networks

These tutorials and instructors were defined and handpicked by the ONUG Board, respectively, who are sending their networking, virtualization and DevOps teams, so should you. Here’s a 3-minute video on why you should enroll in ONUG Academy.

Ixia/Anue ‘s Larry Hart On Its SDN Network Visualization Strategy

May 20th, 2013

Larry_Hart_On_Its_SDN_Network_Visualization_StrategyAs the need for visibility of applications flowing inside networks grows, network architecture itself is changing thanks to network plus server virtualization in data centers, and now Software-Defined Networking. Also trends like BYOD, virtualization, and application mobility are bringing complexity and a new dynamism to today’s networks. Larry Hart, Vice President, Ixia/Anue joins me to discuss how Software-Defined Networking is enhancing the hot network visualization market.

Lippis Report 207: The Killer SDN Applications: Network Virtualization and Visualization

April 8th, 2013

nicklippis.jpgAt the last Open Networking User Group (ONUG) meeting in Boston organized with partner Fidelity Investments, it became very clear that there are two killer SDN applications: network virtualization and visualization. Some argue that network virtualization used for VM-VM networking is not an SDN technology, but I beg to differ. Sure, there are closed and open approaches to network virtualization, but over the next business cycle, the integration of OpenStack and OpenFlow will make it clear that network virtualization is an SDN application, especially as it’s extended to physical networks. The second killer app is network visualization—that is, the ability to monitor network traffic and tweak application performance.   At ONUG Rich Groves, Principal Architect at Microsoft presented his SDN based approach to network visualization he designed with Big Switch Networks, cPacket, IBM, Arista and other suppliers that everyone is now using.  Why is network visualization an SDN killer app? Because it uses SDN technology, and most importantly, lowers the capital cost significantly from existing network visualization approaches while also delivering an entirely new level of self-server flexibility. Companies, such as Big Switch Networks, Gigamon, Arista, Cisco, NetScout, Ixia/Anue, cPacket and others, are now positioning their network visualization offers within an SDN context and for good reason. In this Lippis Report Research Note, I focus on network visualization as an SDN killer app.

Lippis Report 196: VMware Bets Heavy on Virtual Overlay Networking with $1.26 B Nicira Acquisition

July 24th, 2012

If it wasn’t clear before July 23rd that the Software-Defined Networking (SDN) controller market resides within a cloud stack, then it’s clear now, thanks to VMware’s $1.26 billion acquisition of Nicira Networks. VMware is building a cloud stack that’s first to recognize the importance of virtualized networking and places a very high value on it. The multiple to Nicira’s revenue is, let’s say, very high. Microsoft, IBM, Citrix, Red Hat and the open stack community have just taken notice and are in the process of evaluating Big Switch Networks, Arista Networks, Embrane, Pluribus, Plexxi, et al. In this Lippis Report Research Note, we explore this exciting turning point in the open networking marketplace.
