An organization's corporate and 15 regional offices are between 1,000 - 2,000 kilometers apart from each other. Each regional office has a data center that serves between four to six branch offices that are located approximately 30 - 200 kilometers away. At the close of business each evening, the organization shuts down their primary application and transmits new information to each regional office. The amount of new information sent from corporate headquarters each night is around 1.5 GB. Later each night, the application at the regional offices reads the data and generates approximately 50 MB of new information appropriate to the branch offices. What is the most cost-effective solution you would recommend for the organization?
