To ensure ultimate traceability in T2R2, we needed an exceptionally fast and efficient backend that would be able to store all sorts of events.

We started building our own and in parallel kept looking at what was available on the market.

Nothing was getting close to our to requirements like immutability, distributed, cloud-native, streaming until we discovered Kalix.

Kalix enabled us to focus on the traceability business logic rather than on the plumbing.

The Kalix team has recently reported on our case study.
