Core Enterprise Services

Active data still lived on a legacy AS400 database, and the streaming layer ran on Amazon Kinesis — which tied it to one cloud.

Moved active data onto PostgreSQL using change data capture, so the legacy system stayed authoritative until it did not need to be.

Migrated the streaming layer from Amazon Kinesis to Confluent Kafka.

Active data served from PostgreSQL, and a streaming layer that is no longer bound to a single cloud.
