DESCRIPTION

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.

Even super human operations people cant be alerted and take action in under 5 minutes.One outage per year could drop service level to three nines or worse. Monday, August 9, 2010 17.

Cultural ChangesAgile IT and DevOps movements Operations and Developers shouldcollaborate with each other todeliver excellent products Systems Administrators need to become Systems Engineers buildingautomated, fault tolerant systemsnot just maintaining infrastructure More frequent changes, moreoutages (albeit short) to rapidlyimprove IT products and services Process, version control, andautomation are important Monday, August 9, 2010 19.

DevOps ToolChain ProjectProject centered around how to automate and improveinfrastructure management using Agile/DevOps methodologiesDiscussion Topics Open questions on unied pipe architecture Distribution methods: package vs le, rscyn/murder vs yum/rpm vs DFS Conguration management: RPMs vs puppet/cfengine/chef tool? Rollback methodologies for package and cong management tools Controlling and timing package release and cong management tools Log management (aggregating, crunching, charting)Change detection http://code.google.com/p/devops-toolchain/ Monday, August 9, 2010 22.

Summary Automate to improve service, apply leverage Rethink how your operations works Choose tools that can extend and adapt to new types of infrastructure (what does cloud look like in 2015?)
