Option B is the most suitable choice for this scenario. AWS Glue is a fully managed ETL service that can handle data integration tasks. To integrate data from multiple sources, you would first create a data catalog in Glue to store metadata about the data sources. Next, you would use Glue crawlers to scan the data sources and populate the data catalog with tables and partitions. Finally, you would create Glue jobs to perform the actual data integration tasks, such as extracting data from the sources, transforming it, and loading it into the desired destination. You can also use Glue's security features, such as encryption and access control, to ensure the integration process is secure.
