Containers: Innovation or Evolution? Will They Rule the World?

CloudComputingThe latest and greatest thing in the data center is apparently containers. For those of us with long enough teeth to remember the heady days of the early millennium, they look and smell a lot like Solaris Zones.

Containers in their current incarnations are garnering a great deal of attention, especially in the DevOps world, where continuous deployment is the latest word in deployment strategies.

It is said that nothing is new in the world, and with containers, this statement could not be truer. I think, therefore, that an overview of the evolution of the container may be useful.

Another Missile Fired in the Cisco vs. VMware SDN War

Network VirtualizationYesterday I was reading about Cisco’s fourth quarter earnings results, as you do when you are bored and waiting for the next episode of EastEnders to start—well, we all have to take a rest from SDN goodness every now and then. Now, this was interesting for two reasons. It was the last quarter under the leadership of big bad John Chambers and the first announced by new head honcho Chuck Robbins (sounds like a cross between a cage fighter and a liberal comedian). Firstly, congratulations are in order on the results—Cisco exceeded analysts’ predictions of $12.6 billion in revenue, with $12.8 billion and a per-share profit of 59 cents, up almost 4% over the previous year, and an overall year-over-year increase of 4%.

DesktopVirtualizationOn the 29th of July, Microsoft released to the world the latest iteration of its highly popular desktop operating system. Well, I say “popular” because in over 80% of all desktops and notebooks it is the desktop operating system of choice. However, “choice” may be too strong a word, as the OS comes with the hardware, so perhaps “Hobson’s Choice” would be a better phrase.

Business Performance and Agility: Are We Measuring the Correct Metrics?

Speed.In the EUC world, it is euphemistically stated that the only performance metric that counts is user experience. What this means is that from a business and management perspective, it does not matter a single jot how much green is showing in your NOC view; if your users are not happy, you have a problem. Is this the case in the server world? Continue reading Business Performance and Agility: Are We Measuring the Correct Metrics?

Choices We Have Plenty: Your Guide to Virtual Switches

DataCenterVirtualizationI was tinkering around with XenServer the other day. I know I can hear you saying “is that a thing?” Well, it is, but this is not what I am going to talk about today. Time for a tangent shift. I thought I would have a look for a third-party switch for XenServer, but it seems that XenServer is a third-rate citizen in this space, as there is no Cisco Nexus 1kV available for XenServer, even though Cisco previewed it at Citrix Synergy Barcelona in 2012.
