Data sovereignty requires data to remain subject to the laws and jurisdiction of its storage or processing location. In Kafka deployments, this makes data locality a security, compliance, and architecture concern rather than merely a storage choice. section 9.2.1
Regional Kafka deployment
A finance, healthcare, or government organization may reject a broadly distributed cloud Kafka deployment because providers can place metadata, logs, or data outside approved boundaries. On-premises Kafka, private cloud, dedicated regional deployments, or hybrid architectures provide stronger locality control, but increase infrastructure cost and operational complexity and reduce elasticity. section 9.2.1
Architectural responses include:
- Assess regulatory requirements before selecting cloud Kafka. section 9.2.1
- Use dedicated region-specific, private-cloud, or hybrid deployments when locality must be controlled. section 9.2.1
