How do we evolve the IT architecture to enable an ever-increasing set of services while multiple MegaTrends are rapidly transforming the environment? How do you deliver the best possible experience to your users and applications while maintaining agility and keeping cost under control?
Today, in my first blog after the summer break, I’d like to start exploring a topic which is critical to building this new architecture supporting current and upcoming Megatrends – and which can be seen as a Megatrend itself as well: Software Defined Networking (SDN) and the Cisco Open Network Environment (ONE) strategy and architecture.
Bruno Klauser, Consulting Engineer in my team has been focusing on Network Programmability and network-embedded automation for some time – and is currently working with many of the early adopters across EMEAR.
Q: Bruno, with Software Defined Networking being an increasingly popular discussion topic we’re hearing a lot of of comments -- from “nothing new at all” to “complete revolution of IT” – what, if anything, is different from how we built solutions in the past? Read More »
On September 30th at Interop New York we announced the Cisco Nexus 3100 top-of-rack flexible switches. The show floor was buzzing with the news and the Techwise TV video below with Senior Product Manager, Jag Tamvada and self proclaimed Chief Networking Geek Jimmy Ray Purser discuss details of the switches.
In my first SDN blog, I asserted that “Services” -- that is technical support, professional and consultancy services -- are the missing “S” in the SDN debate. I’d now like to apply our Cisco Domain TenSM framework “in anger” to examine in more detail the impacts that SDN may have on your IT services and operations. While come of our competitors will only talk about the network switches and new device protocols, l’ll show how it’s not just the network switches that you should be concerned with: your SDN and Cisco ONE journey could involve impacts across multiple “domains”.
As I bogged about Cisco Domain Ten this past year, I’ve positioned it as a mechanism to help you on your data center journey. Let me now extend that use -- SDN after all is more than just a data center technology play. My experience with Cisco Domain Ten over the past year has helped me realize that it is, in fact, an excellent framework for considering impacts to more general IT services, and not just to the data center . I’ll also illustrate my case with both service provider and enterprise/business/public sector examples.
The following diagram summarizes the areas impacted -- let’s discuss each one.
Someday soon, personal sensors, wearable gadgets, and embedded devices and services may make today’s PCs, laptops, tablets, and smartphones look quaint by comparison. But as the Internet of Everything (IoE) ─ with its diverse array of devices accessing a plethora of existing and new services ─ continues to rapidly evolve, user friendly interfaces mask growing complexity within networks. An article on today’s digital designers in the September 2013 issue of Wired captured how the focus is now “creating not products or interfaces but experiences, a million invisible transactions” and that “even as our devices have individually gotten simpler, the cumulative complexity of all of them is increasing.”
Which inevitably takes us behind the curtain to the exciting challenge of building hyper-efficient programmable networks using virtualization, the cloud, Software Defined Networking (SDN), and other technologies, architectures, and standards.
So far, this blog series on The Programmable Network has described various new and exciting capabilities leading to greater efficiencies and cost benefits. We’ve shared with you how you can now:
Visualize and control traffic using path computation via a network controller
Monitor and optimize traffic flows across network connections
Order services through an easy-to-use online portal which then launches automated service creation tasks
As enterprises are consolidating their IT infrastructure into private cloud (enterprise data-centers) or public/hybrid clouds they’re realizing massive economies of scale in application deployments. Further, they’re taking advantage of XaaS (Software/Infrastructure as a Service) offerings from Cloud Service Providers with Pay As You Go models that increase the speed of deployment and the agility of their business critical applications. This is a major shift in how applications are now being delivered over the WAN to their end-users in branch offices and on mobile/BYOD devices. IT consolidation and virtualization in the data-center are placing a lot of requirements on the enterprise WAN. Business agility and end-user and customer application experience are imposing critical requirements on the WAN. The major challenges that enterprises are facing with cloud migration are: Read More »
