In this post, let’s understand Pega Constellation Development and deployment pattern usage in Docker and Kubernetes. Pega recommends leveraging the Pega Constellation for all the new applications from PEGA 8.8 version onwards. It is a major leap in CX. Constellation uses Single Page Architecture. The browser will orchestrate the react component refreshes. This pattern makes the network traffic lite and provides a better user experience.
