The Amazon Web Services (AWS) Cloud is a proven route to help organizations achieve rapid scalability, reduced time-to-market, and cost-effectiveness in their IT infrastructure. These benefits are delivered, in part, by automation, greater ease-of-use, and simplified management. Many are challenged, however, with legacy network infrastructure and management solutions, as the complexity of managing dynamic workloads, as well as inconsistency in performance and security, can impair many of the benefits AWS provides. SD-WAN helps organizations overcome this challenge by providing automation and simplified management for cloud networking. This whitepaper looks at how Riverbed SD-WAN can help organizations improve performance, agility, and security in their cloud-centric network.
