How SD-WAN and Cloud-based WAN are Helping Businesses

cloud technologyIt all started as a solution for big businesses to communicate with itself. It used to be the MPLSs (Multi-protocol label switching) were good enough for this. They used WAN technology to help multi-branch companies communicate effectively with each other. But they eventually became insufficient so VeloCloud provides cloud computing services for sufficient communication. They came to be seen as having too high a cost with just in themselves, but usually, cost the buyer big because acquiring it necessitates buying a bigger bandwidth. So when a very good and much less expensive alternative came around, many companies ditched it.

This alternative combined WAN technology with Software Defined Networking (or SDN). SDN by itself is a system used for internal data centers at a campus or main headquarters. This is storage architecture. Anyway, WAN united with this and the end product was called Software-Defined Wide Area Networking (or SD-WAN). SD-WAN began as simply a type of Software-Defined Networking (or SDN). It honed itself and is now a form of WAN that both simplifies offices networking and safeguards smooth application performance.

As mentioned, it can replace MPLS entirely or it can supplement it. It also makes adding bandwidth a lot simpler and easier. And it made it was a more reliable way to send communications. There is actually some very scholarly research out there concerning the many benefits of SD-WAN. It all makes sense to switch to using it. Might as well if your equipment is old and needs to be switched anyway. A huge benefit is that it provides an excellent platform for creating a network overlay. Better yet is that it is capable of several different kinds of connections.

But there are many others, such as automated zero-touch deployment, the aforementioned simplified configuration, and the ability to monitor with centralized troubleshooting tools. Users can do all this either through the cloud or through the regional and enterprise data centers using hardware. If you go the hardware route, you can expect to need a lot of equipment. On the other hand, it is often a lot less pricey than a cloud-only WAN. But if you ever move you may wish you had the cloud version anyway since going the hardware route will mean having to move a whole bunch of items.

On the other hand, you will only need to make a phone call with cloud services. Cloud-based WANs also tend to have faster delivery and performance. There are also hybrid applications which allow access and control through both. There are various ways you can do this. The most popular are via links or APIs. Many users have found that this hybrid option usually reduces costs. This is a needed aspect because increasing the bandwidth is a good idea since using (VPN) technology makes broadband use more secure.
