I love the competition and I am a firm believer in the open sharing of knowledge and education.

My philosophy was that if you throw 30 students in the deep end and 8 of them figure out how to swim you will have a good team ready to go. The time frame is extremely tight to learn an insane amount of new technologies, strategies and the “meta” of the competition. This is (roughly) how our weeks we structured throughout the year.

Here is my recommendation for quickly learning at least the basics of infrastructure:

Hardware:

• If you can start with a cluster of at least 3 computers.

  • If not a single computer for a hypervisor will work

  • If not then VirtualBox or VMWorkstation will get you started with the absolute basics until you can get a hypervisor

• If you have a couple old computers or laptops (at least 8gb ram each) then start with those.
