Previously I talked about the growing demands and how the role of IT has to change from a cost center to a business strategic partner. And we also looked at the journey you need to take to deliver IT as a Service. Cloud computing is part of this journey and it is happening – and I mean all types of Clouds – Private, Public and Hybrid. In other words, we are entering the World of Many Clouds. Forrester Research recently published a report that concluded, “Cloud computing is ready for the enterprise… but many enterprises aren’t ready for the cloud.”1 Yet cloud deployments are happening, driven by workload virtualization and changes in application architecture and usage.
Take a look at this short video with Paul Perez (VP/GM of Unified Computing System and CTO of Data Center Group) and me. Paul shares his insights on the trends of how Cloud is changing the way of the IT and the challenges you will be facing.
Guess what? Once again Cisco is here to help you on your journey to the World of Many Clouds. How you ask?

Previously I talked about the growing demands and how the role of IT has to change from a cost center to a business strategic partner. It’s important to acknowledge that getting an organization to the point where it can implement IT as a Service isn’t easy, nor does it take place all at once. Every customer has their own journey and different customers will take different journeys. For some, it’s all about doing what they do now, only more efficiently or perhaps adding new capabilities. For others, it’s about making that full-blown transformation to service-driven IT.
So how do you get there? Each phase expands into a series of key initiatives…
It all starts with moving into more of a unified architecture of network fabric and corresponding operations.

This post is about the onePK software architecture, and how it allows us to consistently expose network operating system (NOS) features to a wide variety of programming environments for IOS, IOS-XE, IOS-XR and NXOS.
For an overview of onePK in general, and some more context, see my October 2012 post and my slides in Slideshare.
The main elements of the onePK software architecture are illustrated Read More »

Is your network ready to help you transform and be the strategic partner that you can be? Let’s face it… Today’s data centers are challenged with siloed resources and facilities… Limited scalability… Poor resource utilization… Growing complexity…Perhaps the biggest challenge is time. When 80% of your resources are dedicated to “keeping the lights on” and managing all what you have, there is very little time left for innovation that benefits the business.
And the reality is that the role of IT has to change – from a cost center to a business strategic partner! Why? Because there are increasing demands on IT to help your business differentiate in order to survive and grow in these rough economic conditions. And let’s not forget that the increasing cost pressures, technology changes, and the advent of game-changers like cloud are forcing IT executives to look at how to deliver IT differently.
These growing demands put even more pressure on the shoulders of IT especially given the current state of your Data Centers. The data center network sits at the core of IT and is key to how IT can deliver services and provide value back to the business.
So what do you do? The good news is that …

When we talk about networks in the data center, there is often talk about bandwidth, 10Gigabit Ethernet, switch sizing, and the changes that have been wrought on the network since the inception of widespread server virtualization. The base operating system that the switch runs on, the networking software itself, is often only discussed in terms of how/when/why to do upgrades. Networking software has more relevance than that, especially from a strategic standpoint.
The strategic nature of networking software is easy to see. But the most important way networking software is important is in the flexibility it can provide over the lifetime of the product line. Poorly written or architected networking software can put a huge burden on the vendor when new features or when major changes to the networking industry occurs. As a customer that matters because the vendor may spend the time and money to accommodate those changes or has to charge an exorbitant amount. It all speaks to the investment protection a vendor can bring. Poor network software equals poor investment protection and a degraded upgrade path.
