Both solutions can help maximize your current resources and technology dollars
Like many technologies that were once available only to large organizations, virtualization and cloud computing are being scaled down for small business use. The two technologies are often mentioned in the same breath as though they’re interchangeable—they’re not. Here’s where the two technologies overlap: Virtualization is one of the fundamental technologies that makes cloud computing work. However, virtualization is not cloud computing.
In enterprise networks, virtualization and cloud computing are often used together to build a private cloud infrastructure. For most small businesses, however, each technology will be deployed separately to gain measurable benefits. In different ways, virtualization and cloud computing can help you keep your equipment spending to a minimum and get the best possible use from the equipment you already have.
First, you need to understand what virtualization and cloud computing are. Virtualization software allows one physical server to run several individual computing environments. In practice, it’s like getting multiple servers for each physical server you buy. This technology is fundamental to cloud computing. Cloud providers have large data centers full of servers to power their cloud offerings, but they aren’t able to devote a single server to each customer. Thus, they virtually partition the data on the server, enabling each client to work with a separate “virtual” instance of the same software. Read More »

On February 3rd of this year, Cisco announced its membership in, and commitment to, the OpenStack community. OpenStack is an open source cloud computing software project founded in the spring of 2010 by Rackspace and NASA, and which provides compute, storage and image management services for cloud computing environments.
In his announcement, Lew Tucker, VP and CTO of Cloud Computing at Cisco, stated:
Since joining Cisco several months ago, you may have heard me talk about the importance of architecture, APIs, and open source in Cloud Computing. So today, I’m particularly proud to announce that Cisco has joined the OpenStack community. The effort here is being led by the CTO organization but also draws on other engineers throughout Cisco’s product groups to help with the design, specification and development of this open source cloud stack. And yes, that does mean code.
Fast forward to September 23rd, 2011. On this date, Cisco, along with an extremely dedicated group of developers from several fellow members, including Nicira and Citrix, delivered the first fruits of that labor. The first experimental release of OpenStack’s cloud network service, Quantum, is now available for download.
Details of Quantum’s functionality and architecture can be found on the OpenStack Quantum wiki page. The source code for the service can be downloaded from OpenStack’s Launchpad repository.

Today’s IT organizations face a broad set of challenges today.
- How to deal with the proliferation of end-user devices? (smartphones, tablets, etc.)
- How to deal with the proliferation of virtualization and it’s new operational model?
- How to adapt to requirement for new application traffic patterns (east-west, VM mobility)?
- How to manage the edges of their networks as work/life locations blur?
- When do they decide to deliver a business need via internal resources vs. external resources?
- With all this technology change happening so rapidly, how do they align their teams?

I just arrived home from a couple of days visiting customers in Asia and I was a little surprised by all the attention around Cisco’s increased competitive posture. It seems some people are surprised Cisco is calling out its smaller networking competitor by name, although I’ve heard few mentions of their Wall Street Journal cartoon advertisements ridiculing Cisco a while back. I guess that didn’t count.
Here’s the issue. If you’re going to claim innovation leadership in networking, you better be prepared to back it up with facts.
What matters most to customers is whether their networking partner is ready right now to help them adapt to, and benefit from, the massive network-centric changes that are transforming their businesses and their customers’ businesses.
My recent trip to Asia provided some great examples of exactly what I’m talking about:
First, Mobility is red hot. Tablet growth is exploding as the shift from the PC to new consumer based devices accelerates. With our service provider customers, the new Mobile Packet Core is THE number one conversation. The Cisco ASR 5000, combined with our CRS-1 and CRS-3, is the most innovative technology available to handle this explosion of mobile data and develop new services to help service providers monetize mobile content.
Twenty of the world’s top twenty five mobile operators are already deploying the Cisco ASR 5000 and this number is only going to increase. We also hear growing interest in Asia for SP Wi-Fi as an alternate method to address the escalating requirements for mobile bandwidth and data services. For sure, there’s a lot of competition for the mobile packet core and SP Wi-Fi, but our smaller competitor from Sunnyvale just doesn’t seem to be relevant in these conversations.
Cloud is on fire as enterprises accelerate their migration to private cloud to capture the economic, operational and agility benefits. In this area Cisco innovations have rocked the industry. Let’s check the facts. From a decade long position of undisputed leadership in data center switching based on our flagship Catalyst family of Ethernet switches, Cisco led the market with the first purpose built data center core switch and operating system, the Nexus 7000 with Cisco NX-OS software. Then we led the market with the introduction of Unified Fabric on the Nexus 5000, the first to consolidate data center networks over FCoE. We also introduced the first data center fabric extension on the Nexus 2000. And the Nexus 1000 was the industry’s first distributed virtual switch for VMware environments. The Nexus 3000 ultra low-latency switch has achieved immediate success in financial services customers and at massively scalable data centers.

As a resident of Austin TX, I got to experience a record setting heat spell and drought this summer. Not to mention, some of the worst forest fires which are yet to be contained. I was fortunate to escape the heat in the last week of August and attend VMWorld 2011.
One of the themes at the conference was Desktop Virtualization – desktop access through a range of devices and access to cloud-based virtual machines. This is a timely issue in light of the June Cisco Visual Networking Index report which predicted that there will be twice as many networked devices as people on earth by 2015. With the proliferation of devices such as the iPhone and iPad, it is not inconceivable that workers will use the same devices in the office as well as home.
Another theme at the conference was management of servers and desktops including provisioning, ongoing maintenance and automation to meet service level agreements. VMWare’s CTO in his keynote also mentioned that some of their biggest investments are around operations management of the virtualized environment.
Not surprisingly, another theme at the conference was Cloud Computing. Whether virtualization is required for Cloud Computing can be a topic for heated debate. Although virtualization is not an integral part of the NIST definition of Cloud Computing, the resource-pooling characteristic of Cloud Services is enabled by virtualization.
These themes prompted me to revisit a study by Forrester Research Cisco sponsored on the basics of management for Cloud Computing. Although it was aimed at Cloud Management, the basic steps and concepts should be valid for any data center on a journey towards a dynamic, connected world. The paper is titled “Elements of Cloud Service Orchestration”. A closer look under the hood is warranted even though the term “Service Orchestration” has taken a life of its own, with Wikipedia calling it a buzzword. A webcast on the top is also available. What do you think service orchestration means in the context of data center management? I am very interested in your feedback.
