The agile admin is written by Ernest Mueller, James Wickett, Karthik Gaekwad, and Peco Karayanev, a group of experienced Web systems administrators and developers who met while working at National Instruments in Austin, TX. It is our vision to help turn systems work into a recognized and effective discipline. Some of our hot topics in this regard include DevOps, agile operations, cloud computing, infrastructure automation, Web security (especially AppSec), transparency, open source, monitoring, Web performance optimization, and more. Come join us as we explore and, hopefully, improve the wide world of Web operations!
