The Norwegian health care sectors success is dependent on the security and availability of enormous amounts of critical data. The state of affairs is that data does not flow. At Norsk helsenett we have recently started using Kafka to secure this flow.

Our critical data is your critical data, and a matter of life and death. This I how we do that:

- Redundancy to us starts with the number 3, creating the infrastructure and using it to manage "always available" services and data, working towards zero downtime and data loss.
- Security is paramount, how did we implement mTLS?
- How do we monitor and support usage of data we cannot look at using the benefits of .Net and SignalR in Blazor together with Kafka.
