“Enterprise class.” Sounds awesome. But does it have any meaning to your business?
It turns out that it does, but we need to dig into a real product example to make it clear. One shining example from Cisco is our leadership in Enterprise class (there’s that phrase again!) 3G/4G. Let’s use this example to highlight how our engineers create “Enterprise class” products by focusing on: Read More »

Anticipation of the upcoming summer Olympic Games has already lifted my spirits. This week I received an invitation from Andrew Millar, the British Consul General in Houston, Texas – it’s an opportunity to attend a viewing party for the opening ceremony later this month. I’m really looking forward to that event.
You may recall that in my last story, the ICT Infrastructure Investment, I shared some of the interesting high-level details about economic outcomes and seven of the the key principles that were used to develop the overall ICT solution.

Lately I’ve been seeing some industry people trying to apply the principles of data center network fabric models to their Wide Area Networks (WANs), and implying that such can be extended through service provider WANs. Data center fabrics and WANs are horses of very different colors with way too many differences for these perspectives to hold up.
Fundamentally they are different beasts with one more easily tamed than the other. Data center networks generally have well known end points and well-ordered designs.
Multi-tenant Data Center Designs
Bandwidth within data centers is virtually unlimited relative to WAN bandwidth. It is much more stable and constrained in its characteristics when it comes to things like latency, loss, jitter, capacity, restoration capabilities – all of which have significant influence on WAN services delivery. The same data center network assumptions exist between each of the end points, which makes fabric modeling for data centers generally a good approximation and thus possible to use.
Some private WANs that interconnect data centers may align closely enough with a fabric model, making it a good enough approximation. But this is a unique case and is essentially Read More »

In a previous blog, I posted the first of three pitfalls of hitching your wagon to the cloud . Today, let’s cover the second pitfall of force fitting cloud into your current security model.
Recently, I had an opportunity to listen to the CIO of a Fortune 100 company talk about top business care-abouts for IT. We have all heard about cloud and virtualization as technology care-abouts, but this CIO boiled it all down to two things that matter for IT: Productivity and Risk. Read More »

In any water cooler conversation or a fireside chat in Silicon Valley, it is impossible to avoid a conversation about technology. Unlike Real Estate, which used to share air time with Tech before the recession, Tech has weathered the storm. We love to talk Tech here in Silicon Valley and thanks to the very high standards of innovation in the neighborhood, there’s always something different to talk about.
Here’s what some of the most common discussions this week might look like…
iJill: “Did you check out the latest iPad?? Its Retina Display, packs more pixels than my HDTV”.
gJack: “Oh yeah?.. my Android tablet has far superior specs to yours, plus it gives me the freedom to root my OS and do what I want with it!”..
iJill: “But, there’s no comparison to the number of Apps I can install and your tablet apps are a joke!”
gJack:” You only get 16GB in your iPad whereas I can get 32GB or more for a lower price”
iJill: ” Yes, but your battery hardly lasts until you complete your blog post, while I am still engaging with my blog readers responding to comments via Disqus while listening to music” …..
