Apache Kafka for financial services
Kafka in banks, payment firms and fintechs: real-time payments and core banking events, exactly-once processing for ledgers, DORA and PCI DSS controls, multi-site resilience and audit evidence.

How self-hosted Kafka is used and controlled in specific industries, the systems it connects there and the regulations that shape its design.
Kafka in banks, payment firms and fintechs: real-time payments and core banking events, exactly-once processing for ledgers, DORA and PCI DSS controls, multi-site resilience and audit evidence.
Kafka for hospitals and health platforms: streaming HL7 and FHIR events between clinical systems, HIPAA safeguards for ePHI in topics, retention limits and integration with FHIR servers.
Kafka on the factory side: ingesting machine and sensor data through MQTT bridges, edge and plant clusters mirrored to a central cluster, segmented OT networks and long retention for quality analysis.
Kafka for utilities and grid operators: smart meter and SCADA telemetry pipelines, separating OT and IT networks, NERC CIP and NIS2 obligations, and multi-site replication for control centers.
Kafka in government agencies: data exchange between departments, sovereign hosting and air-gapped deployments, open-source licensing for procurement, and security controls for sensitive data.
Kafka as the event backbone of a SaaS product: multi-tenant topic design, quotas per customer, change data capture into analytics, SOC 2 evidence and cost control as volume grows.
