Internets of Interest for 29th February 2012

Collection of useful, relevant or just fun places on the Internets for 29th February 2012 and a bit commentary about what I’ve found interesting about them:

From the Experts: Cloud Computing’s Hidden Export Regulation Risks – Article from talking about the fact that using ‘blah blah cloud’ can be classed as an export under US law. And exporting data is illegal.

Blah blah Cloud has gots lots of problems but this is big one. Data geolocation is a huge issue for legal jurisdiction for any company that does business with their respective governments.

Does CCIE still make sense? « by @ioshints -

“As this market evolves, it’s also becoming clearer that customers don’t place additional value on trust and are unwilling to move the most mission-critical applications to the cloud before less-sensitive applications are thoroughly tested and vetted in a cloud environment,” Brown added. tweet

True. They didn’t fail though, we moved to a different solution that worked better. And now the pendulum moves back the other way to centralised control again………..

“As this market evolves, it’s also becoming clearer that customers don’t place additional value on trust and are unwilling to move the most mission-critical applications to the cloud before less-sensitive applications are thoroughly tested and vetted in a cloud environment,” Brown added. tweet

This data center was built on VCE vBlocks. Can’t help but wonder if it’s too expensive to compete with open source, commodity components.

Cisco MediaNet 2.2 Deployment-

Medianet 2.2 Deployment Guide – PDF File. Lots of hard technology goodness. I found the sales section of the Cisco website on medianet to be utter waffle and time wasting. (Cisco sales documentation is very patchy). This is a practical hands on guide to the technology.

Hat Tip to @asholomon from Cisco for the link.

The Raspberry Pi Launch -

We’ve temporarily changed to a static site, while we’re experiencing a very high level of traffic for the launch of the Raspberry Pi. The full site will return once traffic levels have subsided, hopefully later on today. tweet

For up-to-the-minute news on what’s happening, follow @Raspberry_Pi on Twitter1. 1(Only until about 6pm GMT, though, because we’re all going to the pub after that!) tweet

I love that last bit.

OpenFlow 1.2 Specificiation – It’s a PDF file and you can download it from here directly.

Making Effective Use Certification Exam Guides: Reading Ain’t Enough – Ethan Banks on study guides and attitude.

One of the things people do to study for a certification exam is buy The Book (often spoken of in hushed, reverent tones). “The Book” is some flavor of certification guide that’s intended to fill your brain with all of the information required to pass a particular exam. tweet

Facebook: The Wimps Will Inherit the Data Center | Wired Enterprise | – More on Facebook who appears to be field testing my “fantasy next generation data centre” using wimpy cores, dynamic workloads, open air coolings, roll your own storage and lots more fun stuff.

Qfabric and its role in the enterprise « CCIE 31104, what’s next? – Good all round look at data centre fabrics and the Q-Fabric.

The question that has to be asked is the risk worth the potential benefits? In the case of Qfabric in the enterprise I have my doubts. I appreciate the forward thinking and initiative being shown and I do not doubt that Qfabric will find adoption in certain provider circles. There is a reason the KISS (Keep It Simple Stupid) has been viable for so long … It seems to me that, given the information we have now, the downsides far outweigh the benefits for enterprise environments. Stay tuned. tweet

Using VASI to exchange IGP routes between VRF’s – – Nick writes up the results of his answers from the Packet Party the other night.

I attended the packet pushers party on Friday 17th and managed to have some of my questions answered during what was a great show. tweet

We will publish a recording in a couple of weeks.

Your Network Is About To Get Simpler | Virtual Now – Dan Hersey’s Blog – I used to work for Cisco selling Nexus 1000v and now I sell OpenFlow says Dan Hershey from Big Switch

Fast-forward eight years, four of which I spent developing and evangelizing a virtualization specific network platform (the Cisco Nexus 1000V), and networks have not changed at all.  Let’s face it; networking is the last major roadblock to enabling elastic workloads in the data center. tweet

Cogs Bad – William Edwards, Coder -

The first enemy of performance is multiple machines. The fewer machines that need to talk to perform a transaction, the quicker it is. If you can use a local in-process data-store (sqllite, levelDB, BDB etc) you’ll be winning massively. You might even fit your whole app onto one box. If you can use a reasonably fast runtime language (I don’t put the dynamic languages in this pile, sadly; V8 is not fast) you might also squeeze it onto one box. You might not even need tiers. tweet

This approach is the enemy of cloud which encourages the use of many machines and damn the cost. And if you can compress things to a few machines, you don’t really need a cloud.

NEC+IBM: Enterprise OpenFlow you can actually touch « by @ioshints -

Tervela’s engineers ran a number of tests, focusing primarily on latency and failure recovery. tweet

They found out that (as expected) the first packet exchanged between a pair of VMs experiences a 8-9 millisecond latency because it’s forwarded through the OpenFlow controller, with subsequent packets having latency they were not able to measure (their tool has a 1 msec resolution). tweet

Ivan doing field checking that OpenFlow works as promised with exciting results – it works as expected (good and bad)
