As businesses become more digitized and increasingly dependent on cloud-based applications, traditional Wide Area Networks (WANs) are becoming less effective. Software-defined Wide Area Networks (SD-WANs) are becoming the go-to solution for businesses looking to improve connectivity and performance while reducing costs. This article will essentially take a closer look at what sdwan solutions are, how it works, and other relevant information.
What is it?
It is a software-defined networking approach that enables the creation of a virtualized network overlay. In simple terms, it connects multiple sites or branches over a wide geographical area using a combination of public and private connections, such as broadband, LTE, and MPLS.
In traditional WANs, all traffic is typically backhauled through a central data center. This approach can result in high latency and poor performance, particularly for cloud-based applications. With this new technology, traffic can be routed directly to the Internet, enabling faster access and improving user experience.
How do they work?
Sdwan solutions use software to automate network traffic configuration, management, and optimization. This means that network administrators can define policies that determine how traffic is routed, based on factors such as application type, location, and bandwidth requirements.
It also provides intelligence that enables it to adjust network traffic based on real-time conditions dynamically. For example, if a network connection becomes congested, it can automatically route traffic over a less congested link, ensuring that application performance is maintained.
The benefits for businesses
Improved application performance
It enables businesses to use multiple connections, including broadband, to improve application performance. Routing traffic over the most appropriate connection can provide faster access to cloud-based applications and improve overall user experience.
This technology allows businesses to add new sites and applications to their network more quickly and easily. This is because it allows for the rapid deployment of new connections and the ability to manage and configure network policies centrally.
It can help businesses reduce their networking costs by enabling the use of less expensive broadband connections in place of more expensive MPLS links. It can also enable businesses to consolidate their networking equipment, reducing the need for expensive hardware and maintenance costs.
It can provide enhanced security features, such as encryption and traffic segmentation, which can help to protect against cyber attacks. Additionally, it can provide visibility into network traffic, enabling administrators to identify and isolate any potential security threats.
With this new technology, network administrators can manage their network from a single console, simplifying the management of multiple sites and reducing the need for on-site IT staff.
Sd wan solution providers offer a range of software and hardware solutions that enable businesses to implement the technology in their networks. These typically include the following:
- SD-WAN software is the core component. It provides the intelligence that enables network administrators to define policies, manage traffic, and optimize application performance.
- SD-WAN appliances are physical devices that are deployed at each branch or site. These appliances are responsible for routing network traffic based on the policies defined by the software.
- Cloud-based management platforms typically offer cloud-based management platforms that enable network administrators to manage and monitor their networks from a central location.
In addition to these core components, some sd wan solution providers may offer additional services, such as analytics and reporting, application performance monitoring, and network optimization services.
In conclusion, this technology is quickly becoming a networking solution for businesses of all sizes. Its ability to provide improved application performance, flexibility, cost savings, improved security, and simplified management makes it a valuable solution for businesses in various industries.
