SD-WAN allows organizations to combine the bandwidth of 2 or more broadband connections into a single, faster, and more reliable virtual connection. Generally speaking, SD-WAN provides the following 4 benefits:
Immediate Stateful Failover
Aggregation and Compression
Enterprise Security and Encryption
Dynamic Allocation of available bandwidth
Real time statistics and performance metrics
The answer to this question will vary somewhat between the various SD-WAN vendors and how they’ve built their architecture. Here at Bigleaf Networks, we’ve invested in our own Gateway network in major peering centers across the U.S. for end-to-end control of Cloud-based traffic. And our onsite router always sits outside of the customer’s existing firewall for easy self-install (5 to 10 min. install is typical). Our major focus area are:
1. Customers leveraging Cloud-based applications, such as Hosted VoIP, Virtual Desktop, AWS, Azure, SaaS, Office 365, etc.
2. Customers that want to run site-to-site VPNs as a replacement or alternative to MPLS or Private connections
3. Customers that want to build carrier and physical diversity into their Internet environment with intelligent load-balancing, bi-directional QoS prioritization and seamless failover.
Other SD-WAN vendors that replace firewalls and don’t have Cloud Gateway equipment tend to focus more on site-to-site hub & spoke or full-mesh networks by either load-balancing between MPLS/Private circuits and Internet circuits for a “hybrid WAN”, or replacing MPLS/private circuits with VPNs set up on their own equipment.
Hope this helps! We’re always happy get further into the weeds on SD-WAN technology and use-cases through personalized workshops. Reach out to us anytime at firstname.lastname@example.org.
IMHO: any customer needing to “more better” control Quality of Service for voice and/or prioritize any other application over general traffic.
Any customer needing solid, uninterruptible, up time, and/or seamless redundant ISP failover
Any customer looking for “better than VPN” option for their WAN, but can’t spend the money for an MPLS.
bottom line: just about any customer 🙂
(depending on the SDWAN provider, of course. there are big differences in offerings, even from 2 different providers both offering “VeloCloud” or another primary SDWAN option.
