Hasura Cloud and YugabyteDB Managed are integrated to provide a seamless experience for building real-time polling applications. Hasura's GraphQL Engine connects to the database, auto-generating a production-ready API backend, while YugabyteDB offers horizontal scalability, fault tolerance, and global data distribution. The two services can be deployed on any public or private cloud, with YugabyteDB being the only distributed SQL database to provide integration and support for GraphQL applications. A real-time polling app built using React is powered by Hasura GraphQL Engine backed by a YugabyteDB Managed database cluster, showcasing the simplicity of their technology integration. The process involves creating free accounts on both services, downloading the sample application code, connecting to the database, applying migrations, configuring the app, and running it, resulting in a fully functional real-time polling application with automatic data updates using GraphQL Subscriptions.
