IT Roadmap

Meeting the needs of today’s business users is creating ever more complexity in the data center. It’s simply no longer efficient to manually assemble components at the cost of delayed service delivery. As IT leaders take a more holistic view of the data center they’ve started moving away from the notion of silos created by separate network, storage, server technology and administration stacks. At the speed of data, technology and business evolution, flexibility and an organization’s ability to adapt and respond are the true business advantages that IT must tap into.

A Cisco® Unified Computing System™ (UCS) eliminates much of the complexity that makes managing a traditional data center challenging by limiting the visibility needed to contain virtual server sprawl and to improve application performance. Simplified management is also addressed through a single system that spans server, storage and networking—as well as hardware—to create a truly integrated data center that facilitates the need for speed and transparent user experience.

During the last 18 months, Cisco has been conducting customer round tables and research to uncover the themes driving enterprises to transition their network storage and compute infrastructures to the cloud. One of Cisco's forecasts, based on this information, is that 15% of IT workloads will migrate to a cloud-based infrastructure by 2013.

In this video, Chris Osika (Senior Director of Cisco's Internet Business Solutions Group Sevices Provider Practice) shares 4 emerging themes in relation to the cloud:

In summary, the four themes are:

1. Sheer Impact. In the past, it could take up to 45 days to provision a server. Now, companies are reporting an hour or less with data center virtualization. That's a pretty dramatic change.


2. Organizational Change. Companies are addressing the need to re-align in a functional way to take advantage of of virtualization and cloud. When they do so, they are able to enact a fully holistic business transformation.


3. The Ability to Flex. Virtualization with cloud computing not only allows companies to flex compute and storage resources, but to flex the network to reap rewards of economy.


4. Virtual Desktops (VDI) Enter the Discussion. Whereas in the past, the discussion of VDI was limited, it's now included in conversations about the impact cloud computing can have on the overall enterprise.

Do these themes ring a belll with your company? What other themes do you see emerging  in relation to accelrating your company's presence in the cloud?

Gartner is estimating that one out of every four server workloads will be virtualized by the end of this year. However, the research firm argues that enterprises should invest more in the approach if they want to maximize the return they are getting on their IT dollars.

"More than 80 percent of enterprises now have a virtualization program or project, but only 25 percent of all server workloads will be in a virtual machine (VM) by year-end 2010," Gartner reports. Virtualization, the firm adds, is "the highest-impact issue challenging infrastructure and operations."

Virtualization was first introduced decades ago as a means of managing mainframe technology. More recently, it was adopted as a means of enhancing the usage of x86 servers, which comprise 90% of the server market overall.

Now, server virtualization is actively employed throughout the Fortune 500. IT executives consider it a huge win because they can drive server utilization rates from as low as 10% to as high as 70-80% — producing huge savings in the process.

However, some companies remain reluctant to plunge into server virtualization. They cite security concerns, performance issues and software licensing complications among the issues holding them back from embracing virtualization technology.

Despite these concerns, some research firms remain bullish on the technology's adoption. One firm, The InfoPro, reports that more than half of newly deployed servers are virtual machines and predicts this number will climb to 80% by 2012.

That said, the implication of Gartner's prediction — covering "only" one-quarter of server workloads — is that three-quarters of workloads on physical machines have not been virtualized.

This raises some questions about whether executives are investing their IT dollars as smartly as they might. In fact, Gartner argues that eight of every ten dollars that enterprises spend on IT can be considered "dead money" because it does not contribute directly to business value.

“We say ‘dead money’ because, while it is keeping the lights on, it isn’t directly contributing to your business growth or enhancing your competitive advantage,” says Daryl Plummer, managing vice president and Gartner Fellow. “In today’s environment, any corporate function that doesn’t contribute to growth or competitiveness is ultimately expendable. Your placement of resources is more critical than ever to your ability to deliver the growth and competitive advantage that your CEO is expecting.”

The uptake in data center and server virtualization requires that IT rethink their data center networks.  Virtualization requires a new approach  - and perhaps a new vendor choice.

Network optimization is a key issue when it comes to virtualization.  Why? Because virtualization increases server utilization, which in turn increases traffic - creating I/O congestion from the edge devices all the way into the data center.  Within the data center, network demand is geometrically increased as virtualized workloads are distributed across multiple servers. 

Vendors are targeting the network needs of virtualized data centers with a variety of solutions.  These divergent approaches to delivering next generation data center networks can be confusing – and proprietary.  Consequently, choosing the right virtual vendor can be more difficult than ever. 

It’s unclear today which vendor will dominate the virtualized data center network market. What is clear is that IT needs to be smart when selecting next generation technologies:

1. Integrated is better than standalone. Virtualization requires tight integration and scalability between the network and the virtual server architecture.  Buying separate products and knitting them together may be lower cost up front – but will most likely by higher cost in the longer term thanks to the ongoing management overhead to continually tune the products to work together.  Not to mention the finger pointing.  Solutions that are designed to work together from the network through the virtual server architecture will improve initial deployment and ongoing management (and productivity).


2. Avoid vendor lock-in and costly upgrades. As with previous technology advances, proprietary approaches will rule for the first phase of solutions. Each vendor will offer their approach – and over time, will converge to offer open solutions (or integration APIs) to achieve interoperability.  If history repeats itself – market leaders will set the open standards – meaning that buying from an unknown vendor may leave you stranded in your own locked-in world.


3. Double check that roadmap. Ask to see any vendor’s roadmap – as well as for references on their current deployments.  Don’t buy anything without customer evidence of its value.   Ask your network experts to review comprehensive technology roadmaps with each vendor to be sure that vendor is heading in the direction you want to go.

Most importantly – choose a vendor who understands your requirements, your business and can show you successful deployments in customers who mirror your own data center and infrastructure requirements.
