This presentation was given at LinuxCon 2010. The proliferation of cloud computing is inevitable, hosted apps, software-as-as-service and now dynamic on-demand utility computing is becoming the norm. The session will be a fire-side chat style discussion of the types of challenges presented by IT management operations personnel and how they can manage cloud infrastructure using open source tools. The talk will discuss options for deploying and integrating tools that provision, configure, orchestrate and monitor cloud (and physical)infrastructure. The session will appeal to those IT professionals (syadmins, net-ops, developers) who develop and manage infrastructure that resides in hosted environments like Amazon EC2 without disregarding traditionally hosted internal infrastructure.
