Glen Campbell is the manager of the Rackspace Developer Relations Group and the lead developer for the PHP-opencloud library and the little-known Siteframe website framework. His computing experience started in the 1970's programming the COSMAC ELF and changing tubes in an IBM magnetic ledger card reader. He worked on the OpenStack Compute project, including the integration of Rackspace's Next Generation Cloud Servers product, and has presented at various conferences since the early 1990's. Formerly a manager and senior architect at Yahoo!, he has experience in building and deploying extremely large websites that sustain massive traffic loads. Prior to his involvement with the Internet, he was an IT architect and consultant for numerous data management projects. He lives in San Antonio, Texas, and is sometimes mistaken for a country and western singer.
