Just thought I’d open the new year with a quick post about my expectations for 2013 from a technical/personal point of view. I’ve been a little slack in my Blog Posting over the last couple of months, but this has been mainly due to an intense work load due to a surge in large client […] Read More
How-To: Citrix NetScaler GeoIP Restrictions
I had a request from a Hosting Client this week to look at options around blocking malicious users from causing trouble on a local Auction site. As the site was only for Australian and New Zealand users we needed to come up with a solution to block the whole world except AU and NZ visitors. […] Read More

For our ESXi monitoring we have chosen to use the OS – vSphere Service Checks. Post here on how to get […] Read More

While not overly complicated in terms of understanding what and how the SSO Service fits into the 5.1 puzzle, I found that it did add a couple of additional […] Read More
VMworld – The EUC Revolution is Here
A few years ago there was a theory put forward by a certain Apple CEO that we were entering the Post PC Era…while I have never subscribed to that theory (which was affirmed by VMware CTO Steve Herrod at VMworld 2012) it’s obvious to see that the revolution is more based around the ways in […] Read More
VMworld – Where is the Zephyr?
There where some pretty big announcements and reveals at VMworld 2012, but unless I missed something (which was totally possible had any accouncement been made on Wednesday morning) nothing significant/direct was said of Project Zephyr VMware’s public cloud offering. What is slightly confusing is that VMware have been very open in the beta for the […] Read More
Quick Post: From 36,000 feet
This is just a quick post from somewhere in between SF and LA. Got to say that Virgin America is very impressive. Seats are comfortable and the entertainment system is well advanced over Qantas or AA. I won’t be so privileged on the A380 back to Sydney… But I have lots of time to go […] Read More
First Look: Apache DeltaCloud

As described on the website: Deltacloud provides the API server and drivers necessary for connecting to cloud providers. Deltacloud maintains long-term stability for scripts, tools and applications and backward compatibility across different […] Read More

The Backup Delusion – Part 2
It’s been a while since my first post on this topic, but there has certainly been a lot of thought and effort put into this subject since then. At first I envisaged this to be a two part post, but I think I’m going to break this up over a couple more posts, that focus on a […] Read More
