GitOps on Steroids

In this talk we will see how the Elixir patterns such as State Machine, Templating and custom behaviors are used as building blocks for a GitOps based Self-Service platform.

The Self-Service automatically validates Git pull requests with a fast-feedback-loop and interactively engages relevant corporate stakeholders in the review and approval process.

Additionally, external approval workflows are orchestrated when required. Once approved the self-service provisions all required resources in real-time using state of the art infrastructure design principles.
