Your Hybrid WAN already leveraged both MPLS and Internet circuits at all business locations, and gave you efficiencies in route selection and business application performance by selecting Internet paths for some traffic—but it also left some frustrated users in its wake, grouching about inconsistent network response.
Your Hybrid WAN deployment eased traffic congestion and delivered efficiencies from your investments in bandwidth. Yet specifying policies to steer the right application traffic over the right circuit at the right time continues to be a challenge, even knowing what traffic went where is often not easy to ascertain.
And how do you get SaaS traffic to its destination without taking it on a trip halfway around the world?
A Software-Defined WAN (SD-WAN) is a transformational approach to simplify branch office connectivity and networking to achieve:
Assured application performance: Transport-independent performance for the most demanding applications by leveraging the most economical bandwidth available.
Business policy automation: Simplified IT operation, offering zero-touch deployments and one-click service insertion.
Managed on-ramp to the cloud: Direct SaaS cloud access with performance, reliability and security.
SD-WAN technology provisions virtual overlays and moves network management into the cloud, limiting costly on-premise equipment and distributed policy management.
SD-WAN technology aggregates multiple connections into a virtual overlay network.
SD-WAN uses path selection, dynamic traffic engineering and link condition analytics to optimize link and bandwidth use to deliver superior application performance to all users in the most cost-efficient manner. It provides simplified, optimized, shortest-path and secure traffic delivery to SaaS without backhauling traffic through distant data center aggregation sites as hybrid WAN architectures often require.
With SD-WAN you can turn on cloud security services, leverage dynamic tunnel meshing, and rely on cloud gateway services to provide optimal and secure SaaS access from any location in the network.
