This a sample geo-distributed messenger that runs on YugabyteDB database, Kong Gateway, Spring Boot, Vaadin, MinIO and several cloud services.

The messenger can be deployed as a single instance on your local laptop or function across the world in the public Google Cloud infrastructure.

Use this project as a blueprint for designing and building geo-distributed apps with YugabyteDB from scratch.
