Components

The Confetti backend is composed of different components:

  • A Spring Boot GraphQL server in service-graphql. This server serves the main API.
  • A KTor Import server in service-import. This server updates the conference data when needed.
  • Conference data is stored in Google Datastore.
  • Bookmarks data is stored in Google Datastore.
  • The static landing page is served from Google Cloud Storage.

You can run the backend locally with the following task:

Developing locally

For the GraphQL server:

./gradle :backend:service-graphql:bootRun

Note that you will only be able to use the "test" conference as access to the real data requires additional GCP credentials.

For the Import server:

./gradle :backend:service-import:localRun

Deploying to Google Cloud Platform

The backend is deployed in Google Cloud on each push to main.

Confetti uses Terraform to manage Google Cloud infrastructure. The configuration is in terraform/main.tf and the terraform state stored in Google Cloud Storage.

Terraform manages:

  • Google managed HTTPS certificate
  • The static IP
  • The load balancer to listen to that static IP and redirect to GraphQL, Import, Landing, etc...
  • Google Cloud CDN
  • Artifact registry & Cloud Run resources

The DNS is managed outside of Terraform. Once terraform apply is run, it'll output the IP address of the load balancer to configure in Google Domains.
