An Innovative Infrastructure to Capture the Value of the Internet of Everything

As the saying goes, the constants in life are death and taxes. We all know there are more than those two, including change and its counterpart, disruption. Business success will result from responsiveness and adaptation that will happen at a rate and with intelligence that we’ve only begun to get our heads around.  And, most CIOs I speak with are asking about how they can adapt and scale their infrastructure to be prepared as the Internet of Things evolves into the Internet of Everything.

This change brings big implications for IT. The role of IT is changing, in the face of cloud and mobile apps, and the growing understanding that every company is a technology company. From the consumerization of IT to what Gartner Vice President David Cearley calls the “four powerful forces: social, mobile, cloud and information,” IT must increasingly demonstrate it can add value to the business, by rapidly and securely rolling out new services, apps and capabilities in a connected world.

SDN Reflections on the London Gartner Data Center Conference – Part 1

December 6, 2013 at 4:58 am PST

Last week I was in London for the Gartner Data Center Conference.  As always there was a wide range of interesting topics being discussed, all very useful.  Working in Cisco Data Center Services, I am interested in many data center topics, however this year I was interested to hear perspectives on SDN, how the market is evolving, and how the attendees -- including many senior IT practitioners -- are considering SDN adoption.

London's Big Ben at Night

London’s Big Ben at Night

From a Cisco perspective, we were showcasing the recently launched Application Centric Infrastructure (ACI), which generated a lot of interest.  There is growing awareness among our customers that ACI could do for networks and applications what the Cisco UCS has done for the server market (with UCS server profiles in the latter proving a good analogy to help customers understand the potential of ACI).

So what were some of my key takeaways from the SDN discussion I heard here?  And what were the questions that in my view are still not being discussed sufficiently across the industry?

Autonomic Networking – From Theory to Practice

Autonomic Networking is well understood in theory, but real, consistent and extensible implementations don’t exist. In this post I suggest a reason for the lack in execution, and our vision to provide a working, implementable Autonomic Networking Architecture.

Wipe off the dust…

When asking a researcher about autonomic systems, (s)he might blow the dust off a stack of papers, or proudly pull a couple of old books off his shelf. Or point to IBM’s IEEE paper from 2003. From a research perspective, autonomics is well understood. It’s this self-management thing, with all those self-* properties. Self-configuration and self-optimisation for example. Distribution, control loops, and so on. Even the Wikipedia articles are written. So, we’re done, aren’t we?

No we’re not.

Ask your friendly neighbourhood network engineers about Autonomic Networking. The one that proudly hacks expect scripts at night to make his admin database talk to his routers. Or the front line engineer who applies a network service class to one of his customers. Likely, both of them would look at you with big eyes, and after explaining that the network manages itself, intelligently, you’d hear back: “That’s like Skynet, isn’t it?”

No it’s not. Read More »

A Software Aware Society Driven by Sensors, Analytics and APIs

1“Software is Eating the World” is a quote attributed to Marc Andreessen and somewhat further explored by his business partner Ben Horowitz.  Mark Andreessen gives compelling reasons to validate this quote.  To some extend I have to agree with some of his reasons (but I am also a little bit biased as a software engineer). On the other hand, when I read this (and this is partly based on working in different domains on software), I wonder if software is that disruptive? If you look “under the hood” of software applications, you find that a lot of software is based on fundamental software principles that are already 20-30 years old, yet Read More »
