SD-WAN was initially designed as a more flexible and cost-effective solution for connecting branch offices to cloud resources and the core network. And that is still the primary way it is deployed. Replacing static and costly MPLS connections and edge routers with a system that can manage and optimize connections and application performance has helped millions of organizations deploy a more robust and adaptable WAN strategy.
The right SD-WAN solution can do so much more. But far too many vendors have failed to realize the true potential of SD-WAN, or have over-promised on the flexibility of their solutions. It is not uncommon to find SD-WAN solutions, even from major vendors, that are unable to scale beyond 100 sites, provide overly complex management systems, or don’t provide solutions appropriate to meet the unique needs of essential verticals, such as retail. This failure on the part of the vendors limits the possibilities for the organizations that deploy them.
When it Comes to SD-WAN, Flexibility is Key
If you are in the market for an SD-WAN solution or are looking to upgrade or expand an existing SD-WAN deployment, there are some key considerations that should be included in the selection process. Flexibility is one of those critical considerations, and far too many legacy SD-WAN solutions were not designed with the sort of flexibility in mind that many businesses require. This is what you should look for:
- Scalability. Not every remote environment is the same size. Branch offices can vary widely, and an SD-WAN needs to meet the demands of any sized office and support thousands of distributed locations. But new considerations, such as a greatly expanded remote workforce, means that some super users could benefit from the performance and functionality that a traditional VPN connection can’t provide.
