For many months now, we’ve talked about the Journey to Cloud Computing and how an evolution within your Data Center is needed to make that a reality. In many cases, we looked at this from an application perspective, focused on the interaction between automation, applications, servers, storage and the edges of the network.
But many of you have asked us to provide you a broader understanding of the role the Network plays in the Journey to Cloud Computing. Specifically you’ve asked us to highlight several areas:
- What is Cisco’s perspective and strategy around the usage of multiple types of Cloud Computing (Private, Public, Hybrid, Community) and what is needed from the network to interconnect all these offerings?
- How does my business manage the network transitions needed between today’s applications (often client-server), the virtualization of those application, and next-generation web and big data applications?
- What considerations do we need to make within my Data Center as we try and maximize efficiency and scalability?
- What considerations do we need to make at the edges of our networks when the proliferation of devices is almost out of control?
- Are there ways to protect my network investments while still having the flexibility to deal with the business uncertainties that are around the next corner?

I hope you are all packed and ready for Cisco Live – Las Vegas next week. In the Sin City we will demo our innovative products and solution architectures that will help simplify and accelerate your journey to private and hybrid clouds. The best way to quickly learn about our products and solutions is by seeing them “LIVE IN ACTION”. With more than 50-60 demos being showcased across different focus areas (e.g. Borderless networks, collaboration, data center etc.) in the Cisco Main Booth, I thought it would be helpful to highlight the data center specific demos.
Dedicated to Cisco Data Center products and solution architectures, we have total of 12 demo kiosks with different themes as listed below. Each of the kiosks will have one or more demos that will highlight Cisco’s unique offering in that focus area. All the kiosks will be staffed by Cisco experts to answer all your tough questions. I am very excited to be part of the show and would love the opportunity to meet you in person. I will be available at the data center demo kiosk 12 -- “Automate and Simplify Your Journey to Cloud”.

I’m not a car person and I don’t worry too much about what’s under the hood. That means that I’m just a car user, I only want to turn the ignition key and drive. In the Data Center world, the server team is typically a user of the network. Server guys don’t want to know how the network is implemented. They just want their VLANs to extend to the whole network so that they can connect their devices with no constraint, without having to worry about high availability, risk containment, link provisioning… network stuff. That’s precisely what FabricPath is designed to offer them: a network that looks like a single switch, the simplest networking entity. This “Fabric” offers efficient any-to-any connectivity with high bandwidth and low latency, all without having to understand how it works.
Of course, this user perspective is an abstraction. The following Figure 2 represents an example of the physical topology of the network, a Clos fabric, typical in Data Center environments. Note that this could just as well be a ring, a star, or even a network distributed across two sites. FabricPath turns an arbitrary topology into a Fabric and does not lock you into a particular model.

Based on the positive feedback I received from my Cisco UCS videos, I decided it was time to tackle a slightly more complicated set of topics. While it’s fairly easy to come up with a set of keywords that spell out C-I-S-C-O, sometimes it’s valuable to take off the training wheels and go a little broader. So in today’s video, we combine the simplicity of M&Ms with the complexity of VMs. How do we take technology that provides tremendous value to customers and explain it in a way that’s fun and easy to replicate? Well, let’s see what happens… Read More »

I’ve written before (here, here, and here) that Cloud Computing is more than some cool software running on a server. Sure, the applications are the sizzle on the steak (+ all the marketing terms -- dynamic, elastic, on-demand, etc.), but there’s a little more to it than that. A user needs to access the application, get the information quickly (or sent it information), and feel confident that the information was delivered securely. The application doesn’t always know what type of device will access it (PC, Mac, Browser, Tablet, Smartphone, etc.), so it can’t be 100% sure it’ll deliver the best user-experience. And users will demands that applications continue to run regardless of the mobile device’s location. All those demands on applications get a lot easier, and in some cases require, an intelligent network providing the infrastructure.
But people often forget those details because they have become so accustomed to a robust network always being there. They might struggle to define the value of that network, just as Kodak did in defining “original technology” in the famous Mad Men episode (Carousel).
Don’t take my word for it, hear what Cisco Cloud CTO Lew Tucker had to say during a recent set of meetings with industry analysts -- here, here, here, here and here. Read More »
