SD-WAN Vs Traditional WAN: Which is Right for Your Business?


SD-WAN provides greater application performance and resiliency while simplifying the WAN architecture. It also improves network security and reduces management complexity.

With centralized control, an SD-WAN solution steers traffic securely and intelligently, using multiple transport options to deliver a superior application experience. It also moves to an OpEx model, eliminating CapEx and reducing IT expenses.

What is SD-WAN?

The enterprise network is a complex environment with multiple connectivity points to the Internet and internal systems. It’s a challenging space that is continually impacted by threats and vulnerabilities. To meet this challenge, IT and security teams need a simple solution to deploy and manage at branch offices, providing centralized visibility and control across the entire enterprise network.

The answer is SD-WAN. This software-based technology delivers the WAN agility businesses need to support various applications, including SaaS and IaaS. It improves application performance and end-user experience by ensuring traffic is routed to the best-performing WAN links. It prioritizes pathing for high-demand applications such as video conferencing and Voice over IP, and it provides business insight by continuously monitoring WAN performance to identify issues before they become noticeable to users.

Unlike traditional MPLS WAN architecture, SD-WAN simplifies the operational environment by decoupling the transport layer from the logical layer. This allows enterprises to utilize a wide range of Internet services from multiple providers at each location and provides flexibility in terms of cost and quality. It also offers scalability with the ability to add bandwidth on demand, delivering on the “anytime, anywhere” promise. A fully managed SD-WAN solution unites firewall, segmentation, routing, and WAN optimization functions in one centrally managed platform to deliver on the promise of improved productivity and security.

What are the Pros of SD-WAN?

Pros of SD-WAN include improved security for businesses by encrypting data in transit and reducing the opportunity for hackers to intercept and disrupt services. The technology also helps improve network efficiency by enabling traffic to be routed through the best available connections, such as MPLS or broadband internet, based on geographic requirements. Additionally, Software-defined Wide Area Network offers benefits like load balancing and disaster recovery through carrier diversity.

It’s also easier to manage because it centralizes the management of WAN policies for all locations and devices. This can assist in reducing the number of gadgets that IT teams should maintain and assist, in addition to streamlining the procedure of making changes to the community configuration.

Another gain of SD-WAN is that it is able to improve utility performance by using supplying a more reliable connection to the cloud. This may be done thru packet loss reduction and jitter reduction, which may assist in making certain that applications are usually running as intended. Additionally, SD-WAN can provide granular visibility into application performance which can be helpful for troubleshooting issues.

It’s important to note that while Software-defined Wide Area Network can offer significant benefits for business, it does require specialized knowledge to manage effectively. For this reason, many organizations outsource their SD-WAN network management to a managed service provider. 


What are the Cons of SD-WAN?

SD-WAN isn’t just another networking technology. It’s a solution that addresses business problems such as remote access, security, and application performance. It allows IT teams to optimize network resources and lower costs in a world where the cloud, unified communications, and BYOD all demand attention.

SD-WAN also helps companies to improve application performance and reduce network congestion, delivering better connectivity from branch offices to headquarters. Reducing latency and increasing bandwidth can provide more reliable and consistent application performance, boosting employee productivity, customer satisfaction, and profitability.

It is critical to take into account the safety implications of an SD-WAN answer earlier than imposing it. However, maximum answers offer the capability to encrypt traffic and shield records at relaxation and in transit. Some additionally offer the choice to set up a digital firewall this is break away the application-aware routing characteristic of the WAN device.

Keeping your infrastructure flexible and adaptable is critical as the IT landscape changes. With a Software-Defined WAN, businesses can use existing internet connections or even mobile data to connect sites and deliver high-performance applications without the cost and complexity of MPLS. As a result, SD-WAN can reduce network complexity, improve application performance and scalability, enable a seamless onramp to the cloud, and increase flexibility for future growth.

What is the Future of SD-WAN?

SD-WAN is a software-based network solution that offers better control over data flows and improves user experience. It eliminates expensive hardware and allows adding new network connections easily. It also allows the WAN to use a mix of connection types, including MPLS, LTE, and broadband internet, which increases bandwidth and performance while reducing cost. Its centralized configuration and management reduce the need for expert staff at every branch location, further decreasing operating costs.

SD-WAN leverages cloud and net abilities to offer seamless connectivity among headquarters and branches. It permits utility prioritization throughout the WAN, offloading visitors to a lower value and greater reliable service hyperlinks. SD-WAN can deliver a more responsive WAN with the use of a cloud-primarily based primary controller this is always updated to reflect the latest routing and addressing policies. It also can speedily discover and transfer to alternate links based on actual-time traffic tracking so brownouts do not interrupt commercial enterprise-crucial services.

A software-described approach can simplify and automate the complete community architecture, ensuing in a much extra agile community built to help new commercial enterprise model necessities. It can enhance WAN reliability by using imparting redundancy and overall performance improvement and supply a far better end-user revel with fewer human errors. It also can lessen the time to install and control a new community at a branch workplace, saving businesses months of planning and logistical assistance.
