Deploy separate Azure Data Lake Storage Gen2 accounts for each department, implementing strict access controls to ensure data is only accessible to authorized users within each department.

Implement a centralized Azure Data Lakehouse that aggregates data from all sources, using Azure Active Directory for fine-grained access control, but without integrating analytics tools for cross-departmental collaboration.

Utilize Azure Data Factory to orchestrate data movement from various sources into a centralized Azure SQL Data Warehouse, enabling users to access data via Power BI for analysis, but lacking real-time data processing capabilities.

Leverage Azure Synapse Analytics to create a unified analytics platform that integrates data warehousing, big data analytics, and data integration, enabling secure data sharing, real-time processing, and collaborative analysis across the organization.
