Thanks for your interest in the user group. We are a community of AWS users in Chicago. We work with AWS but are not run by, funded by, or part of AWS. As an independent group we are free to talk about success stories, AWS wish lists, failures, tools and more.
Users are familiar with AWS, but please explain the context and abbreviations. There are a lot of AWS services! The most popular talks include demos, sharing lessons learned, use cases, and slides/links to do more research.
*We strongly enforce "no sales pitch" rules*
