26th April 2011 by 1 Comment
Exposing cloud failures The result of the Amazon EC2 failure this week has exposed a number of technology strategies in cloud infrastructure as being less than perfect.

Packet Pushers – Show 42 – Protect My B00B1E5 by Hating on Firewalls
25th April 2011 by Leave a Comment
We covered a lot of topics in this show, mainly hating on firewalls and the lack of security process in most corporate companies.

Musing: Targeted Recruitment Means Bows and Boobs

Geoff Huston has some evidence about how bad it is.

A lot of people regard Virtual Trunking Protocol(VTP) as nothing but trouble. Indeed, it’s hard to find many people who will implement it on their network. I find this baffling – it’s a great tool that dramatically reduces time, errors, and troubleshooting is something that we should all embrace and use wherever we can. Naturally, with great power comes great evil. So, lets be clever instead.
Musing: How Many 10Gigabit Ethernet Ports Do You Really Need ?

I was doing a Data Centre Design recently and did some numbers around the numbers of 10 Gigabit Ethernet ports that need to be deployed. I got a bit of a realisation shock.
