One thing I learned from BioIVT’s transition from Internet-based VPN (Virtual Private Network) to cloud-based SD-WAN is selecting the right networking solution for the use case can have tremendous business impact. In their case, time spent provisioning new locations was reduced by months.
Internet-based VPN, which is the use of IPsec tunnels (or similar encryption methods) and physical or virtual VPN appliances to securely connect multiple sites on a WAN over the public Internet, has been a staple on corporate WANs for years. By providing enterprises a means to reduce bandwidth costs, albeit, with some reliability and performance tradeoffs, Internet-based VPN has served as an alternative to MPLS (Multiprotocol Label Switching) for select WAN connectivity use cases.
While Internet-based VPN vs MPLS was the debate for some time, WAN technology has evolved in recent years. During that time, SD-WAN has emerged as an enterprise WAN connectivity solution that provides a combination of cost efficiency, agility, and cloud-friendliness that neither MPLS nor Internet-based VPN can match. Cloud-based SD-WAN, in particular, has proven to be a game-changer by adding reliability and baked-in security features to the mix.
With all the moving parts involved in making a decision, how can you determine if Internet-based VPN or SD-WAN makes sense for your organization’s use case? We’ll answer that question here.
