I work as a full time Linux Sysadmin and Network admin for for medium to large internet facing services.

Quick summary of my job for non-techies

A large website (for example) will run on dozens of machines (really large sites like facebook or google run on thousands), each running special software that processes the requests you web browser sends and produces your webpage.

My job is to design, plan, build and maintain those machines and the services on them (and other services on which they depend) to ensure the site is working.

I don’t usually update the content of the sites (write the words on it) or the code (the software that is written just for the website) but I look after (just about) all the other technical stuff.

More technical explanation.

I look after multiple server platforms for Internet services. Groups of 1 to 50 machines with with features like GSLB, load balancers, frontend servers, databases, cache servers, DR failover, firewalls, monitoring, graphs, etc

I’ve built and looked after services for email, radius, DNS for ISPs with hundreds of thousands of customers and websites serving thousands of hits per second.

I like to both “build cool stuff” and operate it.

My resume is available on request,

Stuff I do at my current job

Fun stuff I get to play with at work:

  • Websites that do thousands of hits/second normally but can jump up a factor of 10 in minutes (without warning)
  • HP rackmount and blade hardware
  • GSLB load balancing & Software Load balancers
  • Distributed Pops, Our own mini-CDN
  • Having a small site & team so being able to roll-out newish (we try avoid the bleeding edge) technologies easily.
  • Rolling out configuration management.
