Collection of useful, relevant or just fun places on the Internets for 22 September 2014 and a bit commentary about what I’ve found interesting about them:
Cisco ACI Infrastructure Design Guide for brief introduction the product and some of the basic design considerations.
As always, Cisco documentation is well done. Still searching for more so I can understand the product better but I’m not yet convinced that ACI is a worthwhile compared to other products. It is still in beta and maybe it will make up some ground in the future.
Microsoft will save $150MM out of $200MM projected spend by using Azure as their private cloud.
Ormond said that there was a “bow wave” of servers that would be coming to the end of their lives in the next five years, and that replacing them as-is with their workloads left in place would cost on the order of $200 million and would fill the coffers of Dell, Hewlett-Packard, and the other companies that Microsoft buys servers from. Ormond estimated that if the targets to move to the cloud could be hit over the next five years, Microsoft could eliminate about $150 million in that capital expense for servers.
Microsoft is moving all of its internal IT to Azure and this article talks about a 5 year migration plan to complete. Fascinating. Just not that this would not be a ‘public’ cloud but a private cloud.
I’ve been recommending to customers to diversity their IT strategy into different product types to take advantage of cost saving. Garter is recommending a mix of Agile and ITIL:
Bimodal IT also implies that hybrid IT is really simply the peaceful coexistence of non-cloud and cloud application components — not the idea that it’s one set of management tools that sit on top of all environments. VMware admins are obviously attracted to the ability to extend their existing tools and processes to the cloud (whether service provider IaaS or an internal private cloud), but that’s not necessarily the right thing to do. You might run traditional IT both in non-cloud and cloud modes and want hybrid tooling for both — but you should not do that for traditional-IT and agile-IT modes (regardless of whether it’s non-cloud or cloud), but instead use best-of-breed tooling for each mode.
Hard to see a typical enterprise being able to run two sets of processes but the struggle to make ITIL work couldn’t get any worse.
It is time for TFTP to pass from common use. And Lindsay Hill highlights the bad parts of TFTP, especially how slow it is and then highlights some replacements.
I love being reminded that technology has changed almost every aspect of our lives for hundreds and hundreds of years. This article looks smaller innovations that made larger cultural changes possible.
High-quality horse stirrups were a byproduct of such improved smelting techniques which; as Paolo Squatriti, a medieval historian at the University of Michigan in Ann Arbor, points out, enabled a mounted rider to whack his opponents over the head without falling out of the saddle. “This made the ‘knight in shining armor’ possible,” he said.
Warning: This link goes to Forbes.com which has a lot of popups and is somewhat spammy. The article is good though which is quite rare on Forbes.
Cisco claims that shipping fast and often is a customer value. Except it usually bugs, failures, constant time lost to service outages and much more pain besides for the customer. But does it also create a culture inside of Cisco of low quality development when the customers can find the bugs ?
Our customers expect the same quality, simplicity and customer experience from Invicta as they’ve become accustomed to with other Cisco products, so we decided to put a temporary hold on shipments while we address those deployment and experience issues We expect to resume shipments later this fiscal quarter (Aug-Oct).®
If I’m buying from a startup or buying cheap then “buggy & incomplete” is fine but paying Cisco a premium price to fix those bugs ? Thats not a good deal for the customer – what do you think ?
Ubiquity Networks is expanding from WiFi into LAN with its low cost, low frills but full features. 24 x 1GbE ports for $399 is a great deal for branch offices and SME applications.
Ubiquity have built a good reputation at what they do and seem to be gaining traction in their target market.
A signficant part of the Internet broke again:
A routing leak this morning by VolumeDrive was passed on to the global Internet by Atrato causing disruptions to traffic in places as far-flung from the USA as Pakistan and Bulgaria.
The tragedy of the commons continues. A simple mistake impacted a large number of people but no one is to blame.
