While good on the service level, ever increasing bandwith demands by cloud-based applications has rendered the old reliable T1 inadiquate as the T1 only supports 1.5 MBPS speed. Add to it that the cost of a T1 can range anywhere from $300-$500/mo on average, and a traditional MPLS installation becomes very costly depending on the number of remote offices needing support.Read More
