During the last 10 years of system administration I have been involved in a number of data center migrations and build-outs. As these projects came and went I began to see patterns emerge in the set of services and software required to run a successful operations infrastructure. This presentation will describe these patterns, and provide an overview of the Open Source software available to implement them. About Dan: Dan Hanks has been involved with Linux System administration since 1998, when he worked for EagleNet Online, a small ISP in Provo, which, in a sense, was the birthplace of PLUG. After EagleNet he worked as a systems and database administrator for Nothsky/About.com/Primedia/United Online and is currently a system administrator for Omniture. He has varied interests, ranging from computers and technology to astronomy, geology, music, art, and family history research. He holds a Bachelor's degree in Computer Science from BYU, and is the father of 4 adventuresome children. He (occasionally) blogs at https://brainshed.com, and tweets as @danhanks.
