System architecture illustration When a publish request is posted to the /app endpoint, the event will first be saved in the events-registration queue for operational resilience and flexibility.
When an event retrieval request is received, it will respond with results from the internal relational database used for events persistence.
Altinn Event Architecture Flow for processing a single incoming event Sequence diagram - POST event System and service dependencies Internal Altinn Authorization: used to authorize access to endpoints Altinn Register: used to support lookup on alternative subject External Azure Kubernetes Services: hosts the docker containers for microservices and cron jobs in a fully managed Kubernetes cluster PostgreSQL: used for storage Azure Functions: used internally to process and forward incoming cloud events to subscriber webhooks. »
System architecture illustration The solution is supported by multiple cron jobs running in the same Kubernetes cluster, a Kafka server and an instance of Azure Communication services.
The following diagram illustrates the overall data flow.
