What are the benefits of SD-WAN?
The traditional WAN architecture was limited to enterprise, branch, and data center. Once an
organization adopts cloud-based applications in the form of SaaS and IaaS, its WAN architecture
experiences an explosion of traffic accessing applications distributed across the globe.
These changes have multiple implications for IT. Employee productivity may be compromised by
SaaS-application performance problems. WAN expenses can rise with inefficient use of dedicated
and backup circuits. IT fights a daily, complex battle of connecting multiple types of users
with multiple types of devices to multiple cloud environments.
With SD-WAN, IT can deliver routing, threat protection, efficient offloading of expensive
circuits, and simplification of WAN network management. Business benefits can include the
following:
Better application experience
- High availability, with predictable service, for all critical enterprise applications.
- Multiple hybrid active-active links for all network scenarios.
- Dynamically routed application traffic with application-aware routing, for efficient delivery and improved user experience.
More security
- Integrated threat protection enforced at the right place.
- Secure traffic across broadband Internet and into the cloud.
- Application-aware policies with end-to-end segmentation and real-time access control.
- Distribute security to the branch and remote endpoints with NGFW, DNS security, and NGAV
More security
- A single, centralized, cloud-delivered management dashboard for configuration and management of WAN, cloud, and security.
- Detailed reporting of application and WAN performance for business analytics and bandwidth forcasting.
- Template-based, zero-touch provisioning for all locations: branch, campus, and cloud.
More security
- Real-time optimized performance for Microsoft Office 365, Salesforce, and other major SaaS applications.
- Optimized workflows for cloud platforms such as Amazon Web Services (AWS) and Microsoft Azure.
- Seamless extension of the WAN to multiple public clouds.
- Detailed reporting of application and WAN performance for business analytics and bandwidth forcasting
