Interop NY Keynotes: Cisco

September 17th, 2008 by Valerie Barber

After some rousing introduction music, Marie Hatter, Vice President, Network Systems and Security Solutions Marketing / CMO of Cisco began her presentation on virtualization.

Introduction

Virtualization is a word used by consumers and also by IT. But, do we all mean the same thing?

A very cool video from Cisco provided answers to “what is virtualization” from an  engineering perspective, data center perspective, IT perspective and the user perspective (virtual world).

Virtualization is about breaking the bonds between applications and server hardware, nodes and networks, applications and operating systems.

Why is this interesting? Virtualization holds the promise to transform the way we work, live, learn and play.

Why virtualize?

The real estate boom over the last 30 years has driven people to the suburbs. People didn’t mind commuting for an hour with lower gas prices. Today, we have a weak economy and gas prices are high. Something has to change.

Many are opting to stay at home. Businesses are trying out telecommuting, some (like Cisco) are even offering telepresence. This helps by reducing carbon footprint. Corporations are breaking free from physical requirements. The global workforce is also having an impact on the network. These changes are having a huge impact on the network.

We are on the cusp of transitioning from virtualization to VIRTUALIZATION.

“One to many….many to one.”

This is Cisco’s idea of virtualization.

Consider the different roles we play in life - one to many. Spouse, executive, friend, parent, gym rat. This would be “one to many”. This is exactly what virtualization does. It allows you to partition resources off that you can use on the fly.

Where do I start?

Virtualization starts with server and storage. But, it’s the network that touches everything - it spans the physical, the virtual, and the cloud. This provides the connectivity to all these resources. The network brings transparency to the picture. It allows you to better monitor performance and better implement security - great benefits!

Why do I need this?

At Cisco, we saw that we were only using 20% of our storage utilization. We wanted to virtualize our datacenters. When we did that, we were able to get 68% storage utilization. For each year that we were able to defer buildup, we saved $40 million.

From a business standpoint, virtualization helps you differentiate and work faster. Provisioning in minutes, improved productivity and competitive differentiation, using less power (environmental impact), and up the ante of business continuity. If VMWare fails? It’s OK. You can reprovision it on the fly.

Is it for everyone?

IT organizations tend to be siloed. You have the IT side and the Operations side. Each has responsibility. For virtualization to work, these walls have to come down. The concept of virtualization depends on shared resources.

Metcalfe’s Law of the Network Effect

Everytime you add a node to the network, you increase the value. This is what happens with virtualization. Every device you virtualize increases the power of each device. More control of environment and more efficiency.

This leads to…

Cloud computing.

Wow, show of hands from the audience when Marie asked “how many are using cloud computing?” and “how many are using your own clouds?” - not a lot of hands were raised. Interesting considering the coverage cloud computing has and the focus of it.

Cloud computing has three possibilities at Cisco:

• Flexible infrastructure (hosting)
• Abstract services (APIs)
• Application services (SaaS)

Automation is going to be key, and will need to integrate virtualization-aware elements.

Can you imagine if you wanted interoperability in the cloud? People haven’t even begun thinking about it.

Conclusion

As you virtualize, your role will change. You will think more about strategy. But keep in mind these “minefields” of virtualization:

• Insufficient planning
• Lack of standards
• Weak security

Security cannot be an afterthought. It has to be planned. We’ve seen new forms of malware, hypervisor attacks, and root kit infections.

As higher expectations from end users evolve, we’re becoming not server oriented, but SERVICE oriented.

Tips:

• Think holistically
• Consider IT culture - equipment and people
