Neon enables developers to create isolated preview environments using its database branching feature, which allows teams to create a copy of their project's Postgres cluster with unique branches that are completely isolated from each other. Kubernetes and Argo CD can be used as hosting and continuous delivery platforms to automate the deployment of these preview environments. A GitHub Actions workflow is also utilized to manage the lifecycle of the container image and Neon resources, including creating a new database branch and compute endpoint for each pull request. This setup enables developers to quickly test changes in an isolated production-like environment without impacting their main production system.
