An enormous sea shift has occurred in the world of WANs with the advent of software-defined wide area networks or SD WAN Technology. It simplifies the administration and management of a wide area network (WAN) by employing software to automate and prioritize traffic routing across WAN sites and by maintaining operating rules for the full network from a single, centralized interface. The software-defined wide area network (SD-WAN) is not a replacement for the wide area network (WAN), but rather an overlay that adds intelligence to an already existing network topology.
This article outlines the main SD WAN benefits for organizations.
Benefits of SD WAN Technology
Reduced Costs
When compared to the time required to provide traffic instructions on WANs or even MPLS, SD-WANs take just a fraction of that time. Businesses may save money on labor expenses associated with these time-consuming operations by transitioning to software-defined wide area networks (SD-WAN). Additionally, SD-WANs are less costly to set up and maintain. Wide area network (WAN) costs typically account for around 10% of an organization’s overall information technology spending.
Better Performance and Reliability
Although traditional wide area networks (WANs) route traffic through a data center before sending it to the internet, SD-WANs route traffic directly to the Internet to provide more secure and faster connections.
You may also set up rules for applications that you use often, such as a customer relationship management system (CRM) or a voice-over-internet protocol (VoIP) service, to ensure that they always have a particular amount of bandwidth and performance. With SD-WAN, you may expect more responsive email without network latency delays, more dependable hosted VoIP solutions without audio quality dropouts, and better video conversations with no visual quality changes. You can achieve all these benefits without sacrificing picture quality.
Agile Cloud Enablement
One way to go to the cloud is by using SD-WAN. More and more businesses are embracing cloud computing. Remote locations may connect directly to the cloud using SD-WAN. This makes it possible for employees to access cloud applications from any location without requiring the main network to handle any extra traffic. This eliminates the need for backhauling traffic. By letting branches connect directly to the Internet and prioritizing mission-critical apps, SD-WAN increases the performance of cloud applications.
Increased Business Agility
SD-WAN solutions also provide improved network performance and agility. Common network issues like jitter and latency are considerably reduced since software-defined wide area networks (SD-WAN) can automatically route your traffic over the fastest and most reliable connection.
SD-WAN allows you to build wide-area network (WAN) services like bandwidth and firewalls more rapidly. As a result, businesses can outsource operations to branch sites without having to hire information technology professionals. Businesses can swiftly raise or lower bandwidth in response to changing business demands, providing them with greater flexibility to stay ahead of the competition.
Enhanced Network Security
Data security has become a necessity as a result of the increasing number of cybercrime incidents that are happening simultaneously with the growth of digital transformation. Organizations utilize traditional wide area networks (WAN) to ensure the security of data sent from several devices. There is no doubt that traditional wide-area network (WAN) solutions can successfully manage security. To do this, traditional wide area networks (WANs) utilize a large amount of equipment per location, branch, and office.
SD-WAN technology provides the highest level of security because it integrates security processes into its architecture. Companies in a range of industries are already switching to software-defined wide area networks (SD-WAN) because SD-WAN’s default encryption capabilities ensure the complete security of critical data.
Easy and Quick Deployment
Regardless of the size of the company, any information technology (IT) setup needs a network to provide an accurate connection. In terms of implementation, transitioning to a software-defined wide area network (SD-WAN) is critical, regardless of whether you have several branches, or a small business scattered across the country. When a company chooses to employ SD-WAN, it provides a solution that simplifies the deployment and management of all its wide-area network (WAN) networking services.
Better Control
As applications may use a substantial amount of data, it is critical to have control over which programs are permitted to utilize the bandwidth that your business provides. SD-WANs provide this level of control. Traditional wide-area network architectures cannot analyze packets and route them based on priority. Because these systems are software-based, they may contain quality-of-service standards, ensuring that the relevant business applications have the bandwidth they need to work effectively.
Conclusion
Based on the above, corporations can reduce IT costs and eliminate network issues with the implementation of SD-WAN. Businesses of various kinds, from startups to big companies, have already started utilizing SD-WAN owing to its numerous benefits and opportunities.
