Traditionally, businesses relied on expensive private lines for network connectivity, offering limited bandwidth at a high cost. The rise of the internet and Virtual Protocol Networks (VPNs) brought new options, but also created challenges in protecting data with increased network complexity, adapting network capacity to meet growing demands and maintaining control over a geographically dispersed network. This is where Software Defined Wide Area Network (SD-WAN) comes in. SD-WAN represents a modern upgrade to our information technology (IT) infrastructure, offering a more efficient and secure way to connect our business locations.
Ease of Management
SD-WAN makes it easier to control the network by using Graphics User Interface (GUI). SD-WAN offers a central control center for an entire network, making things simpler and more efficient. It allows setting of policies for entire networks from a single place. This eliminates the need for complex configurations on individual routers at each location. In the past, network settings could get out of sync across different locations, however, currently, SD-WAN ensures a consistent network design throughout an entire organization, giving complete control and visibility. In case one connection fails, SD-WAN can seamlessly switch to another to ensure uninterrupted network operation. In general, SD-WAN’s centralized control streamlines network intricacy, conserves time and resources, and guarantees uniform performance in every location.
Improved Security
With the increasing transfer of data to the cloud by businesses, the importance of strong data protection measures and cybersecurity risks have become more prominent. SD-WAN enhances cloud firewalls to offer added security for cloud-based applications. Also, traditional networks often send data back to headquarters for security checks, SD-WAN eliminates this by enabling direct and secure connections to the cloud from any branch. This feature simplifies security and saves time by managing security for all locations from a single platform. SD-WAN is therefore a key component of SASE (Secure Access Service Edge). SASE provides a comprehensive security solution for today’s increasingly remote workforces. In short, SD-WAN makes cloud security easier and more efficient, keeping data protected no matter where users are located.
Improved Connectivity
SD-WAN embraces new technologies like 5G and satellite internet, giving a wider range of options to connect locations. SD-WAN can instantly switch data traffic to a faster, available connection. This keeps the network running smoothly and avoids disruptions. Additionally, SD-WAN keeps the network up and running even if a device fails, thanks to backup features. It offers cost savings by letting cheaper internet connections alongside traditional lines, and by simplifying network management. Switching to SD-WAN can pay for itself and save even more in the long run.
Direct Cloud Access
Linking branch locations to cloud applications in traditional WAN systems can be costly, including entry to critical Software as a Service (SaaS) applications. In contrast, SD-WAN provides direct and optimized access to cloud services, eliminating the necessity to route traffic through central hubs. Rather than relying on set paths, SD-WAN uses flexible routes that adjust based on real-time network conditions. This system guarantees a seamless transfer of data across long distances, reducing interruptions. Consequently, users benefit from better teamwork, less annoyance, and an overall upgraded user experience.
Enhanced Performance
SD-WAN provides the flexibility to customize its features and integrate additional security or monitoring tools, allowing a tailored network for specific needs. SD-WAN prevents bottlenecks and congestion by efficiently routing traffic through various connections such as MPLS, broadband, or cellular. This leads to quicker data transfer rates, decreased lag, and an improved overall network experience for users. SD-WAN also gives priority to important applications such as video conferencing and Voice over Internet Protocol (VoIP) calls, guaranteeing they receive the necessary bandwidth for optimal performance. This eliminates delays, dropped calls, and frustrating buffering, keeping your employees productive.
