Latest Blogs from Greg Ness
Today virtualization is creating new demands for another tech disruption.  Perhaps the first shots in this revolution were fired last week at an all day working session of networking legends and “Young Turks” at the SRI Infrastructure 2.0 meeting.  Time will tell, but the level of inte...
There is a revolution coming in the network equipment industry and it was awe-inspiring to recently be in the presence of the revolutionaries.  They represented some of the best and brightest minds in the network industry, assembled for a full day at SRI in the heart of Silicon Valley....
During a lunch with Peter Coffee last May at Interop Peter made a comment that really stuck with me. He said that tech marketers are essentially anthropologists. Our conversation wandered around a bit, from our upcoming Interop panel on cloud computing to the advantages of variou...
During a lunch with Peter Coffee last May at Interop Peter made a comment that really stuck with me.  He said that tech marketers are essentially anthropologists.    Our conversation wandered around a bit, from our upcoming Interop panel on cloud computing to the advantages of various ...
A series of blogs began a speculation about the impact of virtualization on the network. It’s certainly fair to suggest that the network has had little impact on first stage VLAN virtualization, or virtualization-lite. The real question, however, is whether or not virtualization (or VM...
Multiple network and virtualization bloggers are addressing concerns about the impact of virtualization on the network, as networking experts prepare to meet at SRI in early September.
As I ranted about how networks today resemble yesterday’s factories I think I inadvertently stirred up an even larger issue.  My buddy Doug Gourlay pushed the implications a bit further in his Network World blog, suggesting that the network could be at a kind of turning point:   ...
Many of today’s large enterprise networks are burning cash and are overly dependent upon layers of manual processes (like DNS, DHCP and IPAM for starters) to stay available and secure.  Networks were created this way from the start; we architected networks to work just like the environ...
Virtualization and cloud computing have generated plenty of buzz because of their potential to reshape the economics of information and technology.  Yet most of that potential is still “cooped up” in the VLAN, driving impressive gains in server management, yet within strict confines. ...
This weekend Chris O’Brien (San Jose Mercury News) referred to an “identity crisis”  at Google, which immediately reminded us of a litany of technology companies which have ended up dabbling in too many markets for their own good.  Breadth ultimately undermined synergy.  It...
I moderated a Cisco panel last week at Cisco Live! and it was readily apparent that enterprise cloud still required plenty of work from vendors and enterprise IT. No one was ready to endorse either a centralized or decentralized architecture (a move to the powerful intercloud); perhap...
Thin Margins, Change and Differentiation   As we watch the explosion of cloud events, press releases and panels is anyone getting a sense of déjà vu all over again?  It wasn’t that long ago when Webvan was going to transform the grocery business with new technology and processes.    Af...
The intercloud is the most interesting development in cloud computing (and perhaps the data center) since the migration of hypervisors into production environments.  It’s a model for driving incredible scale and efficiency from IT systems and hardware, and it can be architected for bot...
I’m moderating a panel July 1 on the data center of the future made up of a great team of executives from Cisco, Oracle, NetApp, VMware, EMC, APC, Emerson and Panduit.  Hoping to catch up with a few friends after the panel.  Drop me a line if you’re attending. [...]
Two recent posts on Cisco's blog shed light into where they see cloud computing going for the enterprise. And my is it sexy.
I don’t know who coined the “intercloud” term, but it is a big step forward in defining the enterprise cloud endgame.  See this Cisco blog and recent intercloud preso.   As sexy and compelling an idea as it is, the Intercloud would probably today be a bane according to Mark...
Virtualization and cloud computing are promising to change the way in which IT services are delivered and, in effect, transform computing as we know it today. I think the promises are likely to come true, if and only if critical technology issues are addressed. Nicholas Carr told a...
You can get the slides for today’s DNSSEC webinar with Dan, Cricket and Scott here.  The version with audio and slides will be available at the dns security center and the DNSSEC solution section next week.  You can follow Cricket’s answers to questions asked about DNSSEC at the new Cr...
A few months ago I blogged about the Three Horsemen of the Coming Network Revolution.  One of those “horsemen” was the netbook computer.  Now Microsoft wants to rename it. Maybe it has something to do with the impact of the netbook on the hard drive PC market and the powerful relations...
After Interop I moderated a Future in Review (FIRE) panel and had the pleasure of asking executives from Infoblox, Cisco, F5 Networks and VMware about their perspective on infrastructure 2.0.  The first part of the panel talked about the problems with today’s static networks, including...
As network and IT practitioners gathered in Las Vegas (Interop) and tech thought leaders conveyed on San Diego (Future in Review) the week of May 18th, there was more than a weave of flights running between them related to the timing and impact of cloud computing on the enterprise IT i...
DNS Tools If you are looking for DNS tools check out DNS test (or DNS freeware) at the Infoblox web site.  You’ll find links t plenty of tools, freeware and additional resources to help you manage DNS.   Interop If you’re planning to attend Interop feel free to visit the Infoblox booth...
Cloud computing and virtualization are promising more dynamic systems with unprecedented cost savings; and network industry leaders are promising more dynamic networks capable of keeping up with the increased rate of change (with these systems). In order for the benefits to be delivere...

I recently posted about the Dizzying Economics of Cloud Computing when it occurred to me that the technological barriers must be equally mystifying for many. So I thought I would initiate a discussion about the barriers to the adoption of cloud computing by the enterprise. At stake...
As I mentioned at 3 Major Barriers to Cloud, the transition from tech services silos to unified cloud computing fabrics will trigger rapid growth and integration in network monitoring and dns appliance solutions.  Integrated, automated, IP address management will be consolidated into G...

Static networks are already costing enterprises more on a per unit basis as they grow, per this Fall 2008 Computerworld survey. Increasing network costs will only reduce funds available for network automation. This recent TCO comparison between Google and Microsoft is just the begin...
  The billowing state of cloud computing -from expansive, hazy definitions to product proclamations establishing a new level of irony for the term “vaporware”- has clouded some potentially interesting debates about technology and business and the increasingly strategic importance of th...
A Tale of Two Networks was a lengthy blog about the need for network automation as a result of rising complexity, more endpoints and more system mobility.  A key point buried in the blog was related to the increasing importance of IP address management and DNS appliances.   I called ou...
Cloud computing and virtualization are driving new forms of IT, new requirements for vendors and new career possibilities. Today more than ever, legacy tools, investments and tactics are introducing ever-increasing risks. The race between enterprises who automate their network and th...

Infoblox has just released a new IP address management online product demo. The IPAM software demo takes less than ten minutes to guide you through the highlights of the new release, including smart folders, network map, network discovery, IP map and delegated administrator.    Infobl...
Virtualization could easily be called the most critical enabler of cloud computing.  After all, it decouples applications from hardware, freeing up companies from being tied to specialized hardware and enabling new mobility potentials for processing power.  Those potentials could allow...
Preparing for the Shift to Club Cloud Computing   A few weeks ago I talked about the coming cloud computing war by discussing the formation of multi-vendor cloud-driven alliances and their implications for the IT industry.  Now that Cisco has announced its unified computing initiative ...
Whether you’re a small business considering cloud services or an enterprise contemplating public or private cloud services, it pays to understand some of the technical challenges and players likely to have a significant impact on the availability, security and costs of those services. ...
In the last 12 months networking vendors have discovered that they are extremely relevant to the spread of system automation, especially virtualization and cloud computing.  Today’s Cisco Unified Computing announcement has capped a series of strategic developments taking place in the l...
The coming network revolution will be driven by three major developments in computing. I came back Friday a.m. fresh from the FIRE conference Meeting of the Minds planning session in Seattle with a head filled with ideas about where the IT industry is headed and what it will mean for t...
While the press and blogs are buzzing about cloud computing, VMware has made probably one of the most significant cloud-related announcements ever made; and with vShield Zones has added even more distance between rivals when it comes to data center and cloud security.   Last year at VM...
