Cisco SD-WAN - Traditional and Legacy Architectures (Spanish)

These were all positive changes, but not without a certain amount of pain. In particular, the traditional WANs were struggling with these new demands. The WAN architecture worked well when all connections from branches and a distributed workforce flowed back to a central data center through MPLS lines, where security policies were also applied. But the hub and spoke WAN architecture broke down as more direct internet connections were needed to access multi-cloud resources and SaaS applications. Continuing to backhaul all traffic to data centers before routing to internet cloud applications results in increasing MPLS costs, bandwidth inefficiencies, increased latency, and poor application quality of experience. In addition, WANs were often composed of components from multiple vendors, limiting the visibility and control over performance and troubleshooting. SD-WAN was designed to answer these challenges. The technology provides methods to prioritize critical business traffic and take advantage of internet broadband connections—previously used for backup and redundancy—to connect directly to multicloud resources. SD-WAN simplifies the management of the wide area network fabric with a controller-first overlay that is independent of transport layers—MPLS, Ethernet, internet, leased lines, DSL, LTE networks, and soon 5G. SD-WAN controllers intelligently choose among the available transport mediums to deliver the best application performance as defined by IT service level agreements (SLA). #1toops #SDWAN #WANLegacy #Cisco
