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 interest and discussion was exhilarating and timely.  Vint Cerf, Bob Grossman and Dan Lynch did an incredible job setting up the session with the help of SRI. Virtualization Demands will drive the next Network Revolution My take on why we met: Because of the spread of virtualization the IT industry is already experiencing the effects of an increasing disconnect between system and network automation.  Virtualization, for example, increases the rate of change and can create new levels of network complexity (see virtualization-lite) because of the proliferation of static vLANS (virtual network...

The Network Beneath the Clouds

Lew Tucker's response to the Lew's Law blog further helped to clarify the point I was trying to make about the rise of IT automation and the network's pivotal role: While I'm sure this is more obvious than brilliant, the cost of computing will continue to fall bounded only by the cost of the power to produce the computation. We're simply turning electricity into computation and communication using electrons to move around bits. What cloud computing does is to use automation, scaling, multi-tenancy, and a competitive marketplace to bring us closer to this lower bound for the cost ... (more)

The Cloud's Next Killer Apps

The public cloud has been promoted as a low cost alternative to physical data center infrastructure, mostly to small and medium-sized businesses. That has driven the creation of a robust category of cloud migration services which has emerged as these smaller businesses have made considerable investments in moving their apps from colocation and data center environments into public clouds. Enterprises, however, have been notably slower to invest in public cloud and cloud migration, at least in proportion to their overall IT budgets.  There are many reasons for the slower enterpris...

The Next Technology Boom is Already Underway at Cisco, F5 Networks, Riverbed and VMware

Greg Ness's Blog Infrastructure2.0 is the next technology boom. It is already underway. Cisco, F5 Networks, Riverbed and even VMware promise to benefit from this new infrastructure and the level of connectivity intelligence it promises. (More about these companies and others later in this article.) Cloud computing has become a reality, yet the hype surrounding cloud has started to exceed the laws of physics and economics. The robust cloud (of all software on demand that will replace the enterprise data center) will crash into some of the same barriers and diseconomies that are faci... (more)

Will Virtualization Neutralize the Network?

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 VMotion specifically) will stay contained within ever denser VLANS.   F5 Networks MacVittie [...] ...
