Small businesses and non-profits may opt for Platform-as-a-Service solutions such as Heroku to avoid the operational burden of managing their own infrastructure. However, PaaS solutions quickly become cost-prohibitive for compute- or memory-intensive applications. In this talk, I’ll demo an open source infrastructure automation toolchain based on Ansible, Github Actions, Vagrant, Packer, Terraform, and Sentry. Once instrumented, this toolchain incurs a $0 recurring cost and can be safely and trivially scaled up. Each component of the toolchain requires minimal operational expertise and is managed through a UI. State-change notifications are routed to email or a Slack channel, ensuring everyone stays on the same page. Test, deploy, monitor, and scale transparently, and with confidence! The talk will demonstrate how to make the most of free, open source infrastructure tooling to fully automate tests, monitoring, code deployment and infrastructure deployment. You can get a lot of mileage out of free!
