What is SD-WAN?
Software-Defined Wide Area Network (SD-WAN) distributes network traffic across WAN and utilizes software-defined networking (SDN) to determine the best way to route traffic to and from data center sites and branch offices. SD-WAN can replace or work with Multiprotocol Label Switching (MPLS), and it can be delivered directly (through carriers) or by Management Service Providers (MSPs). It can manage multiple kinds of connections all through a single interface.
Benefits of SD-WAN
Simplifies Management
Since SD-WAN is a centralized, cloud-delivered WAN architecture, it makes it easy to scale across multiple endpoints – whether those endpoints are in your branch or the cloud. You can also automate configurations and policies through Zero-Touch Provisioning (ZTP). This way, you do not have to allocate specialized IT resources each time a policy changes, or you add a new application. Therefore, having SD-WAN helps not only to reduce human error but also simplifies what you have to manage.
Improves Your Applications Performance
SD-WAN enhances the performance of your applications by utilizing a combination of WAN optimization methods. It also automatically knows when and where to shift traffic to links that have enough bandwidth to support each of your application’s requirements. Therefore, with SD-WAN, your applications will always have high availability (with predictable SLA).
Increases Your Security
SD-WAN helps to enforce threat prevention by distributing security at the branch level. This way, your data does not have to travel back to your data center or headquarters for advanced security protection (like a firewall). In addition to integrated threat protection and secure traffic flow, SD-WAN also helps to increase your security by providing real-time enforcement when you have network problems.
Cost Savings
With an SD-WAN architecture, you can eliminate or reduce your reliance on pricy leased MPLS circuits by sending your less-sensitive data over inexpensive public internet connections. This way, you can reserve your private links for your critical information. SD-WAN’s is so flexible that it can help you reduce the need for over-provisioning, and it can lessen your overall WAN expenses.

WHAT PEOPLE ARE SAYING
”The Cloud Truth is my go-to Trusted Advisor for next-generation technologies including UCaaS, SD-WAN, and Datacenter. Our most recent project with the Cloud Truth saved my firm over $1M annually in transport costs by moving from MPLS to IP with SD-WAN. All of our cloud & telecom projects start with the Cloud Truth. They make IT easy by saving me time and money ”
– Ben R, Global Network Infrastructure Manager, CapcoCASE STUDY
Global Latency Issues
CHALLENGE: The Cloud Truth was approached by a client who was experiencing latency issues when it came to a critical application in the Asia Pac region. The client was interested in an SD-WAN solution, but didn’t know where to begin the research process.
OUTCOME: The client completed our proprietary SD-WAN matrix form, and The Cloud Truth was able to narrow the vendors from seven to one. This one vendor had the capabilities to address their specific issues.
SOLUTION: Following a brief POC, which addressed their immediate issue, the client was able to apply the solution Enterprise Wide and completely illuminate the issue.
