Kong Konnect's Runtime Groups provide a streamlined way to manage multiple configurations for Kong Gateway through a single interface, enabling users to test infrastructure changes in staging environments before deploying them to production. This feature is particularly useful for organizations that need to isolate changes, such as testing new rate-limiting features, without affecting live services. Users can create a staging environment using the Runtime Manager in Konnect, and with the help of the decK command line tool, copy and modify existing service configurations. The process involves applying changes locally, testing them, and then promoting them to production, facilitated by GitHub Actions which automates the deployment process based on branch commits. This approach enhances workflow efficiency by integrating declarative configuration management with GitHub Actions, ensuring that configuration changes are consistently managed and applied across different environments using a single Konnect account.
