Clouds presentation, aws meetup v2
This document discusses challenges faced by a system engineering team supporting multiple DevOps teams and projects on AWS. Manual creation and management of AWS CloudFormation stacks became inefficient. The author developed a Ruby gem called "clouds" that allows managing CloudFormation stacks from the command line similar to git, with stacks stored in source control. This allows mass stack updates in minutes rather than days, easy cloning of stacks, and self-service environment creation for developers. A demo is provided and the benefits of standardization and automation through clouds are discussed.
