Greg Ness's Blog Cloud computing has replaced virtualization as the new hot topic of 2008. Yet underneath the headlines a very basic shift is taking place in the network that promises even more conversations in the very near future. Let’s call this shift the rise of Infrastructure 2.0 or the result of escalating pressures on an already tired network infrastructure. Over the last three decades we’ve watched a meteoric rise in processing power and intelligence in network endpoints and systems drive an incredible series of network innovations; and those innovations have led to the creation of multi-billion dollar network hardware markets. As we watch the global economy shiver and shake we now see signs of the next technology boom: Infrastructure2.0. Infrastructure 1.0 - The Multi-billion Dollar Static Network From the expansion of TCP/IP in the 80s/90s, the emergence of... (more)

Today's Networks Not Yet Ready for Enterprise Cloud

Enterprise networks are not ready for broad enterprise cloud IT services a la Nicholas Carr. 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 industry. It was clear from a multitude of thought leaders, vendors and data center professionals that today’s networks are not ready for the deployment of many forms of cloud computing, especially the multi-s...

Network Automation is Inevitable

The network industry could be entering yet another new stage of innovation and growth, fueled by a flood of new demands and an increasingly likely new tech refresh cycle driven by increasing network infrastructure automation and control. At the core of this new cycle is a flood of new devices being attached to the network, and at an unprecedented pace. Connectivity, or the ability for a network to recognize what is attached, becomes critical as technology users accumulate IP addresses like children building Pokémon decks. ... (more)

Hybrid Cloud Is Not Public Cloud

There is a temptation to think that all cloud operating models are identical and are commonly driven by interest in commodity IT, or IT delivered at the lowest possible cost.  For many (especially early) cloud customers may certainly be the case.  I predict, however, that hybrid cloud will be driven by very different operating expectations, driven by new solutions that set new IT productivity standards.  It will be driven more by value-added IT, or IT services delivered at the highest level of productivity and speed.  The current popular forms of cloud can be difficult to enter an...

The Coming Cloud Computing Wars

The cloud computing meme continues to billow as Juniper and IBM announce a cloud management partnership rumors swirl about heavy petting between VMware and shareholder/partner Cisco. A few months ago it seemed like every cloud discussion included Google and/or Amazon; now it appears that “the network infrastructure issue” has finally reared its head and ushered in networking and management leaders into the cloud conversation. More cloud watchers are discovering that cloud apps -at a minimum- will put more burdens on the network. As IT services decouple from hardware the network ... (more)
