multi-regional deployment on AWS in Japan, Europe and US

A.
The logistic software has a 3-tier architecture and currently uses MySQL 5.6 for data persistence. Each
region has deployed its own database
In the HQ region you run an hourly batch process reading data from every region to compute cross-regional
reports that are sent by email to all offices this batch process must be completed as fast as possible to
quickly optimize logistics how do you build the database architecture in order to meet the requirements’?

B.
For each regional deployment, use RDS MySQL with a master in the region and a read replica in the HQ
region

C.
For each regional deployment, use MySQL on EC2 with a master in the region and send hourly EBS
snapshots to the HQ region

D.
For each regional deployment, use RDS MySQL with a master in the region and send hourly RDS
snapshots to the HQ region

E.
For each regional deployment, use MySQL on EC2 with a master in the region and use S3 to copy data files
hourly to the HQ region
