Employees based in Estradas de Portugal's remote office locations found that key applications were running slowly over the WAN, which was reducing their productivity. The company also used a network of local servers and backup systems, which was difficult to support and maintain. Estradas de Portugal deployed Riverbed Steelhead appliances across its data center and branch offices. The result was that key applications could be accessed much faster, and cost savings were achieved by removing a number of local servers and backup systems. Considerable savings were also made by Riverbed's WAN optimization solution negating the need for Estradas de Portugal to purchase additional bandwidth.
