SD-WAN stands for software-defined wide area network which is a software-defined wide area network that utilizes device components to control network operations. Dedicated management software virtualizes network hardware in the same way as hypervisors and other components virtualize data center operations.
SD-WAN is a technique for using software to make wide area networks smarter and more flexible. Actually, what is the use of this SD-WAN? According to an article published on Technopedia, SD-WAN can help wide area networks to handle network traffic with a specific protocol while providing an intuitive interface for users.
Not only that, but SD-WAN can also support features such as firewalls, gateways, and virtual private network tools for privacy. Apart from that, SD-WAN can also help with redundancy, per backup and restore, and troubleshooting. Why is SD-WAN important? This is because SD-WAN can solve common problems in IT organizations such as downtime which can affect the reputation and bottom line.
If you have this, you need an IT solution that is agile, flexible, and can save costs. With the existence of SD-WAN, the problems mentioned above can be overcome with a new approach that also brings company scale and security. That’s why SD-WAN is becoming one of the most popular networking solutions available today. There are 5 advantages or advantages of SD-WAN that can be obtained as follows:
1. Lower Connectivity Costs
The first advantage of SD-WAN is that it can reduce ongoing operational costs by switching to expensive MPLS (Multiprotocol Label Switching) lines to commodity broadband such as fiber, cable, DSL, or even cellular technology.
2. Higher Performance for the Cloud
A further advantage is that with SD-WAN, new lines can be added quickly and easily to sites that require more capacity. By linking sites directly to the internet, SD-WAN reduces the bottlenecks and delays common to longer WANs.
3.Multiple Link Resilience
Traditional WAN environments usually have one incoming network link to each location. With SD-WAN, multiple links from different ISPs can be used, eliminating a single point of failure that can bring down the network.
4. Higher Agility
When you open a new branch, time is money. SD-WAN allows you to quickly set up a reliable and secure network, using whichever ISP is most suitable for each location.
5. Optimized Use of Resources
SD-WAN allows you to intelligently assign the main application to various links, including internal paths and Internet connections, providing a different Quality of Service (QoS) assurance for each. This allows you to apply the right resources in every situation to maximize performance and productivity while minimizing costs.
