We outline existing flavours of SD-WAN available on the market. Part 2 of a three-part mini-series exploring SD-WAN technology from an enterprise perspective.
This is the second in a mini-series of three reports which seek to explore SD-WAN technology from an enterprise perspective, covering the challenges that SD-WAN is designed to address, the differing flavours of SD-WAN product on the market today, and how we envisage SD-WAN-type services evolving in future.
The first and third reports in the series are:
- Enterprise networking challenges: How can SD-WAN help?
- Predicting the future: Where next for SD-WAN?
This report examines the role that different types of SD-WAN solutions can play in helping digital enterprises address their growing networking challenges.
SD-WAN as a solution to the networking challenges of digital enterprises
In the first report, we discussed some of these challenges. These revolve around the need to carry a growing range and volume of mission-critical, application-specific data flows – reliably and securely – across a hybrid multi-cloud, multi-domain and distributed WAN environment. This includes different types and sizes of enterprise sites, branches, campuses and remote workers served by diverse access networks on a 24/7 basis.
We highlighted seven main networking challenges that SD-WAN products and services are designed to address, as follows:
- Managing the costs of WAN links
- Improving control of hybrid WAN and multi-cloud environments
- Assuring service and prioritising business-critical traffic
- Introducing new sites and capabilities
- Preventing attacks and mitigating security risks
- Managing different network domains and services across the whole enterprise
- Future-proofing enterprises’ advancing requirements while reducing complexity.
