Traditional WAN (Wide Area Network) is used to connect various branches or campuses to applications hosted on servers in the data center. For connectivity and reliability, MPLS circuits are used that aren’t working for cloud computing. As the world is changing rapidly, cloud computing has taken over the tech world, traditional WAN has become outdated. The solution to this problem is SD WAN products.
What is SD-WAN?
Before going any further, let’s take a look at what SD-WAN is. It is a network that addresses the current IT challenges. An SD-WAN (software-defined wide area network) virtualizes the WAN connections.
It develops a visualized network by decoupling the network software services from the hardware. This new WAN network approach helps lower operational costs and improves the usage of resources for multisite deployment. It is designed to support applications hosted in public or private clouds, on-premises data centers, and SaaS services.
The changed network game
Enterprises used private and dedicated MPLS networks between branches, which was bandwidth-constrained and expensive. But as the utilization of cloud-hosted applications increased among the enterprises, MPLS started to prove inadequate.
Enterprises needed a network that allows them to quickly access:
- Every location in the network
- Cloud applications over the internet
Is SD-WAN the right choice?
The network technology optimizes traffic over various connections and delivers a better experience anywhere. It steers traffic to the best link and remediates if any transmission issue comes up, ensuring high performance of applications.
Let’s have a look at how SD-WAN products benefit your business:
- Network agility
To be slow in today’s era can cost you so much. Speed matters the most as customers have high expectations from you and expect to get what they want at the time they want it. SD-WAN makes sure that multiple branches can connect in a streamlined and efficient manner to understand the immediacy.
- Simplified management
SD-WAN makes connectivity seem so much easier by simplifying everything from the management perspective. The fewer issues also result in higher reliability.
- Application performance
Businesses today, rely mostly on their applications. Once the app goes down, everything starts to go down from there. But with SD-WAN, the performance of the application is enhanced, meaning there will be managed traffic for improved user experience with greater consistency.
There are plenty of vendors when it comes to picking the right SD-WAN solution for your business. You have on-site solutions in application or software form and cloud services. Make sure you choose a reliable vendor that is efficient as well as reliable.
