SD-WAN is a Business Necessity
Explore the key characteristics and business impact of SD-WAN and learn what to look for in a solution provider.
The Problem with Traditional WAN
Traditional WAN design is based on multiple devices stacked in the branch office with siloed management and disparate WAN links connecting them.
Expensive Bandwidth
Limited bandwidth of expensive private/MPLS circuits inhibits rollout and impacts performance of applications. At the same time, private/MPLS WAN redundancy is complex to deploy and manage.
Unpredictable Application Performance
Application traffic over Internet links lacks SLAs for predictable performance. Every change in the application quality of service requires manual changes across the branches and the data center.
Data Center Dependence
With no direct access to cloud resources from the branch with the archaic hub and spoke network design, the traffic is backhauled through the enterprise data center with heavy performance penalties.
Complex Infrastructure
Traditional WAN includes multitude of single-function devices and appliances connecting via different WAN links. This infrastructure sprawl causes complexity of branch IT management.
SD-WAN Makes Branch Networks Better
Virtual WAN
Deliver a network overlay with multiple links from different service providers to form a unified pool of bandwidth. Provide superior performance and high availability for applications independent of the underlying transport links.
Simplified Branch Services
SD-WAN provides insertion of network services whether on the branch CPE, in the cloud, or in regional and enterprise data centers. Software-defined flexibility with automation and business-policy abstraction simplify complex configurations of traffic routing and policy definitions.
Cloud Optimized
Enterprise-grade performance is assured even when traffic is going to cloud applications. Incremental overlay design abstracts the software layer from the underlying hardware layer and the physical transport to make an elastic network.
Pay-as-You-Grow Model
With SD-WAN, you can deploy a wide area network on-premises or in the cloud. SD-WAN eases the services insertion with application-aware forwarding to enterprise data center or cloud. Cloud-based management enables pay-as-you-grow subscription model for cost efficiency.
