A software WAN is also known as software defined networking, where data is moved about within the system’s hard drive. This eliminates the need for external routers which can get clogged up with traffic from other sources. This virtual sd-wan network uses switches and routers not only within a virtual network system, but in each device as well. This greatly reduces the initial cost and it is cheaper to fix one broken segment.
One of the biggest benefits is that your network will be centralized with less hardware. This provides greater flexibility and is much easier to maintain from an administrative point of view. Updates are now able to be implemented simultaneously through the switches and routers in your network.
This turns your physical network into a virtual one, providing you with the ability to adjust the entire infrastructure without replacing all your equipment. You can add or subtract work loads on each device instantaneously. Applications are now possible to send over broadband and wireless technology that couldn’t be done in the past. This is due in part to new algorithmic nodes as with Voice Over IP has been doing for a long time.
This is fantastic news for smaller businesses who couldn’t afford the costly upkeep or on call IT personnel. They now have access to the flexibility and configurations that was once exclusive to big business. It may cost initially, but companies will reap the benefits in the end by keeping up with ever changing technology that traditional networks could not do.
The introduction of the Cloud WAN does away all the expensive equipment that was necessary to maintain a traditional network. Now, all of the administrative tools sit in the cloud are accessed with browsers. Gone are the point to point trappings that private networks have relied on for decades. Companies are now able to send and access traffic on public clouds. The cloud option is an even cheaper alternative than software WAN’s that still need multiple routers.
Private and public cloud WAN’s can provide the ability to grow or shrink during peak and off peak usage hours. You will also have access to skilled IT professionals when using services such as Microsoft and Google. Off site servers provide time and money that can be devoted to other areas of your business that need improvement. Lastly, network outages will be fewer and shorter because they are no longer subject to local grid outages.
When choosing between either a software WAN or cloud WAN you should consider money and maintenance. The latter still needs to rely on routers and switches similar to traditional networks. The former will be virtually and literally out of reach and requires little to no maintenance. Both applications can be software run, are much cheaper than hardware WAN’s and save a lot of time on configuration and speeds.
