Virtualization Demands Will Drive the Next Network Revolution

Wisdom:

I think the network equipment vendors who focus on dumb pipes will face shrinking habitats and increased competition from the likes of Huawei and cloud providers. IMHO the second stage of virtualization will create more load requirements. The question would be the use of dumb versus smart beyond the enterprise network and the clouds.

Virtualization Demands Will Drive the Next Network Revolution

Dave:

I don't provide investment advice. Each of these companies has their own internal financial dynamics, etc which I don't track as I'm tech-foocused. I'm long VMW, SVVS, AMZN, SNDK and am watching CSCO as their UCS evolves. I'm not betting that they'll dominate but rather that as a set they'll have a disproportionate advantage based on their market positions and technology. I like SNDK because of the rise of flash memory; SVVS because of their cloud savvy and VMW because they seem to understand hte importance of the network and phase 2 virtualization. I think AMZN is also well positioned. Again, I'm looking at tech withj a 1-2 year horizon.

Thanks,
Greg

Will Virtualization Undermine Network Equipment Vendors?

Greg:

More than Infoblox. Addressing is a core issue... but work needs to be done with multiple players. Ultimately the network, systems and endpoints need to know each other's status on a continual basis. That's bigger than the automation of DNS/DHCP and IPAM etc as you likely know.

Thats why I think the SRI event is happening and Infoblox is a core part of the conversation. It will take a collaborative effort among multiple companies to establish connectivity intelligence in a way to build infrastructure 2.0.

This matters (the shape of this evolution) because it will impact who is relevant and strategic to virtual and hybrid infrastructure (the future of networking as we know it).

Thanks for the shameless plug opp... but I'll pass and answer that Infoblox is very relevant/strategic/nec... to this direction but not the entire solution. That is why there are several companies talking about this issue and SRI is sponsoring an event.

Stay tuned. :)

Reality Checks for the Billowing Cloud Computing Fantasy

Disappointed:

The issue is much bigger than "cloud complication." Its about risks and significant tech barriers to real enterprise adoption and the lack of preparedness for networks. Lets put it this way: if cloud isn't viable for the enterprise how viable will it be for SMB? Yes it can replace some apps (with thin apps and multi-tennant hosting); but if it isn't economical (the elastic intercloud that can follow the moon) and is really just larger VLANs with more VM density... then it won't live up to the "Big Switch" hype.

That issue may noty be that interesting to you, but its an important consideration for enterprises exploring cloud service (versus software as a service or infrastructure as a service, etc) models. And there is a sizable quantity of traditional servers powered up 24X7 (wasting energy) that could be replaced if the issues are properly addressed. If they're not, then we will go on longer wasting the energy used to power these servers while they're not be usied. According to the panel at FIRE, the amount consumed annually by those servers amounts to the entire amount produced by wind (I think it was about 5% that Gouraly mentioned).

New CIO Acronyms: DNS, DHCP, IPAM

User:

Some CIOs are more comfortable with keeping critical infrastructure in-house, especially if they can use dns appliances, etc to reduce costs and boost availability. If its not a big decision point (infrastructure = plumbing = boredom) then it might be worthwhile taking a new look. That being said you don't need my approval to outsource and dismiss DNS, etc as old news.

Thanks for the comment!

Why Cisco and F5 Networks Love VMware and Microsoft

Artful and Broken:

Thanks for your comments. Citrix is certainly worth mentioning as well as Juniper, Riverbed, Blue Coat, IBM, Foundry and others. I typically refer to the leaders in each category (application, endpoint and network intelligence) as metaphors for many other players, versus listing them out. So you are correct that Citrix is worth mentioning. I also think that they have come around on the security issue, after their CTO had a very public row with virtualization security visionary Chris Hoff.

Thanks,
Greg

Infrastructure 2.0 Outlook: Timing Is Everything

I think there are at least two approaches. You invest in the service providers or htose who sell equipment/solutions to them. For service providers its a question of who can deliver "real" cloud services (versus the marketing hype). This in itself is a lively discussion on tech blogs/Twitter etc. For the suppliers of gear/solutions its a matter of who you think will deliver the best solutions (the cloud switches/meash/automat... and be designed in by the service providers.

It is very messy at this point placing bets on who will win. The point of this article was to suggest that a big shift is coming and there are a set of milestones that one could follow to help guide a strategy. I think that Cisco, Arista (privately held) and VMware are hte furthest along to delivering on the promise of I2.0, but they certainly don't have it wrapped up. Citrix has been complementing their legacy middleware expertise and base with some great acquisitions and has IMHO been building a solid ecosystem. Yet I think VMware has led when it comes to enterprise go to market. They were the first to embrace the power of virtualization security, even during the early stage one virtualization deployments; and IMHO they were also faster in building relationships with the network equipment/security leaders.

That being said, the fruit of those relationships has been long time coming. I attribute to the challenges "binding" virtual and physical infrastructure and engaging network teams. When that happens (and by whom) will be IMHO all that matters.

I'm not making investment advice... but rather offering a perspective on tech trends that could be game changers. One cannot rule out Microsoft or Amazon either... because of footprint (MSFT) and business model compatability (AMZN).

All opinion.

Virtualization Demands Will Drive the Next Network Revolution

Jades:

You know... you should be paying me for these kinds of plugs tied to the column. :)

Will Virtualization Undermine Network Equipment Vendors?

Phil:

I wasn't saying that the comparison was based on an identical set of impacts, but rather that in both cases the demands on the network were underestimated. If you are in the virtualization-lite camp then you perhaps won't see material demands, except perhaps related to security and vmotion (I/O) within the vLAN. Some firewalls and ids solutions might require hairpins and extra processor cycles depending upon how they're deployed. With VoIP the network challenges were discussed openly in the press...

Thanks for the comment

Will Virtualization Undermine Network Equipment Vendors?

Wisdom:

That is certainly one of the schools of thought... driven in part by the success of the VLAN. The second school shows a peak to the tactical VLAN payoff and a disruptive evolution of the network.

VoIP ultimately drove more network revenue because it increased hte demands on the gear. Very few pros considered those impacts for a variety of reasons... but then they happened.

Thanks!

Thanks. I'm tempted to post the agenda for the Infrastructure 2.0 blackboard session at infra20.com to "address" some of htese comments. Let me check with the event sposnors/champions.

Z:

There are a few more titans in the battle but I think you've identified those who could be called "strategic" (value add) versus "tactical" (cheap IT service). I think how IT evolves and how well the network embraces the virtual infrastructure may have a lot to do with who wins the most.

Netbooks May Disrupt Cloud Computing

I think networks will have to me more intelligent, powerful and dynamic for them to replace the level of communications that takes place between apps and processors on the modern laptop.

Three Technology Barriers to Cloud Computing

LA Tech:

Likely that cloud will continue to evolve along specialized vertical applications and into SMB versus "just in time IT" for the enterprise. I think it is thise confusion between the vertical and the ultimate vision where most of the confusion comes from... and yet the network impacts of virtualization and cloud gets obscured.
