Although MPLS network links can be managed within a software defined WAN architecture, SD-WAN can offer a less expensive, more secure, and higher performing option.
- Deep Network visibility
- Intelligent Application Routing
- Cost efficient*
- Embedded security such as vNGFW, AutoVPN and segmentation
- Direct cloud access
- Single click connectivity & resource allocation
- No analysis of data
- No application recognition or bandwidth management
- Cost inefficient**
- Dedicated line, traffic is backhauled for inspection
- Backhauled to data centre then to cloud.
- MPLS Can have several week delay to add capacity
* Providing optimised, multi-point connectivity using distributed, private data traffic exchange and control points.
** Distributed locations are connected to a central data centre using a hub and spoke topology. In this model, all WAN traffic, dataflows and network transactions are routed and distributed centrally. In practice, this is highly inefficient and costly compared to an SD-WAN solution. Transactions, including access to cloud services or the internet, required traffic to be backhauled to the data centre for processing and redistribution.
Use case example.
One key benefit from SD-WAN is its overall lower
total cost of ownership.
Implementing an SD-WAN solution allows you to
- No need for technical expertise to set up remote sites
- Troubleshooting is no longer a time-consuming process
- Mitigate the need for manual intervention with changes
- Less reliance on MPLS due to leveraging cheaper internet links
