Let’s Clear Up Some Misconceptions – Is SDN Relevant to the Enterprise WAN?

June is summer weather in the San Francisco Bay Area, but quite different from the June I was used to in Boston. A common misconception around Mark Twain and his relationship with San Francisco summer is that he never said “The coldest winter I ever spent was a summer in San Francisco.” But he did say: “Cold! If the thermometer had been an inch longer we’d all have frozen to death.”

June is always exciting here and in Europe. NBA playoffs are on and the Giro d’Italia just ended with the Italian Vincenzo Nibali winning it emphatically. The San Antonio Spurs have been so good but King James brought the Heat back from a certain death in Game 6. Game 7 decides it all!

Equally exciting is the buzz in networking circles, especially in the Bay Area, around Software Defined Networking (SDN) and how it is potentially commoditizing networking infrastructure. However, just as we cleared up that misconception about Mark Twain, I’d like to clear up some points around WAN challenges with cloud migration and how SDN might be applied to overcome these challenges.

In this blog post I will discuss the challenges in the Enterprise WAN and relevancy of SDN in overcoming these challenges.  In part 2, I’ll cover how the Cisco ONE Enterprise Networks Architecture addresses these WAN challenges. Read More »

Cisco Partners: How Well Can You Adapt and How Quickly?

If you heard Padmasree Warrior, Rob Lloyd and Edzard Overbeek during Day 2 of Cisco Partner Summit, you know the overall focus was on Cisco technology strategy, innovation and services. Padma and Edzard shared additional thoughts with the Cisco Channels social media team during interviews at the event, and so did Rob – particularly as it relates to Cisco’s unique value proposition to customers and how Cisco and partners can offer simplicity, flexibility and agility when designing solutions.

Let’s hear what Rob, Cisco President, Development and Sales, wanted to make sure Cisco partners took away from their time at Partner Summit:

The Model for Next Generation IT

The promise of the Internet of Everything (IoE) looms near, and as the networked connections between people, process, data and things exponentially increase, the opportunity for private industry sits at $14.4 trillion USD.  And the potential for humanity is limitless.  This means that the future of information technology (IT) will look very different.

Realizing the potential of IoE will require what I have been calling the Model for Next Generation IT.  It’s a familiar view of IT, but the value is shifting in each layer.  And as the value shifts, we’re seeing new business models emerge, in great part due to the adoption of cloud computing and everything as a service (XaaS).  But we must keep in mind the value that the network delivers in the future as I wrote in my earlier blog, “Three Truths About Networking – the Next Chapter”.

In the past, category leaders that provided separate components defined the infrastructure layer of IT. In fact, we referred to them by what they delivered – server companies, storage companies, networking companies, security companies and so on.  But as we see the needs for IT shift with the consolidation of major technology trends like mobility, cloud, M2M (or the Internet of Things / IoT), big data and analytics, and a whole new breed of applications -- the infrastructure needs in IT have changed.

Cisco, IBM and the Linux Foundation discuss Open Source in Networked Environments

Hi all,

As we continue to expand on the conversation of the Cisco Open Network Environment (Cisco ONE), this week provides yet another educational opportunity (Register here) to discuss a topic that has become some what top of mind to customers, partners and even investors alike. This is the topic of open source in networked environments.  While Cisco has always been known for open standards,  it has now stepped up into the open source conversation in a fairly big way over the couple of years with its contributions to both OpenStack and the more recent OpenDaylight project under the Linux foundation.

Using Open Source in Networked Environments

While the topic of Open Source is not new,  the topic of using open source in today’s networks has gained momentum in recent times, which, not surprisingly, coincides with the broader conversation of open networking. While there is considerable interest, there is also a lot of confusion. Several questions pop-up:

- What is Open Source vs. an Open Standard?

- How do Open Source consortiums work?  What is the governance model?

- What are the security implications of Open Source based implementations?

- What are the likes of Cisco and IBM doing in this space?

- What is the Open Daylight project?

- Is open networking the same as open-source networking?

If you would like to get an overview of not only  mechanics behind open source projects and communities, but also get a great overview of the recently announced OpenDaylight project from the Linux Foundation, I invite you to register for the 4th session of the Cisco Open Network Environment webcast series “Using Open Source in Networked Environments – Discover the Possibilities and Benefits” broadcasting on June 18th at 9 a.m. PST.

OpenSource

Joining me in this webcast as I host three industry luminaries in the Open Source community including Michael Enescu, Cisco Chief Technology Officer for Open Source Initiatives at Cisco, Daniel Frye, Vice president of Open Systems Development from IBM joining and Jim Zemlin the Executive Director of the Linux foundation.
