Old Army is a large retail store chain operating about 1,000 stores across the United States and Canada. Each store is connected into the Old Army data network, which is used primarily for batch data transmissions. At the end of each day, each store transmits sales, inventory, and payroll information to the corporate head office in Atlanta. Most traffic is sent to and from the Atlanta headquarters. The Atlanta office is connected to 20 regional data centers, and each regional center is in turn connected to the 3070 stores in its region. Network volumes have been growing, but at a fairly predictable rate as the number of stores and overall sales volume increases. Consider cloud computing will be employed in Old Army.
