+* [Web PubSub Service](./infra/modules/webPubSub.bicep): Deploys a Web PubSub service.
+* [Private Endpoint for Web PubSub](./infra/modules/privateEndpoint.bicep): Creates a private endpoint for the Web PubSub service.
+* [Web PubSub Hub](./infra/modules/webPubSubHub.bicep): Creates the Web PubSub Hub.
+* [Web App Service](./infra/modules/webapp.bicep): Deploys the web app service.
+* [Custom Web Domain](./infra/modules/customWebName.bicep): Assigns a custom domain to the web app.
+* [Private Endpoint for Web App](./infra/modules/privateEndpoint.bicep): Creates a private endpoint for the web app.
+* [Private Endpoint for Storage](./infra/modules/privateEndpoint.bicep): Creates a private endpoint for the web app's storage account.
+* [Application Gateway](./infra/modules/appgw.bicep): Creates an Application Gateway to serve the web app and Web PubSub service endpoints.
