Answer: Azure integration runtime

## Analysis of Integration Runtime Options ### Requirements Summary: - **Data residency**: Data must remain exclusively within the UK South region - **Minimal administrative effort**: Reduce operational overhead ### Evaluation of Options: **A: Azure Integration Runtime** ✅ - **Data Residency**: Azure IR can be explicitly configured to run in a specific region (UK South). When both source (Azure Storage) and sink (Azure Synapse Analytics) are in the same region, and the Azure IR is configured for that same region, data movement occurs entirely within that regional boundary. - **Administrative Effort**: Fully managed by Azure - no infrastructure provisioning, maintenance, or updates required. This aligns perfectly with the "minimize administrative effort" requirement. - **Optimal Choice**: Meets both requirements efficiently. **B: Azure-SSIS Integration Runtime** ❌ - **Data Residency**: While it can be deployed in a specific region, SSIS packages may introduce complexity in ensuring data doesn't traverse outside UK South during processing. - **Administrative Effort**: Requires SSIS package development, deployment, and maintenance - significantly higher administrative overhead compared to Azure IR. - **Overkill**: SSIS is designed for complex ETL transformations, not simple blob-to-data warehouse copying. **C: Self-Hosted Integration Runtime** ❌ - **Data Residency**: Can technically ensure data stays within UK South if deployed on-premises in that region, but introduces network complexity. - **Administrative Effort**: Highest administrative burden - requires provisioning, maintaining, and updating the self-hosted infrastructure, including security patches and performance monitoring. - **Not Recommended**: Contradicts the "minimize administrative effort" requirement. ### Conclusion: Azure Integration Runtime is the optimal choice because it provides regional control for data residency while being fully managed by Azure, thus minimizing administrative effort. The explicit region configuration ensures data movement occurs entirely within UK South boundaries without requiring infrastructure management.
