Understanding the aspects of SD-WAN |
Posted: September 25, 2017 |
More often, enterprises and other business units that have operations in more than one location have integrated connections. It makes it easy for data to be accessed and relayed from one particular branch of the business to the other simultaneously. This connection is prompted by a software technology referred to as software-defined networking that is applied to WAN connections. A WAN, for instance, can be used to create links to several branch offices to central corporate networks or connecting data centers and branch offices over relatively large geographical distances. The primary goal of SD-WAN technology is to provide a typical business-class, straightforward and secure cloud-enabled WAN connections using rather open and software-based technology. Numerous companies offer these services in the market, and these companies have invested hugely to ensure that they provide quality service to their customers. It should also be understood that the other seasonal WAN technology vendors like Cisco and Riverbed that are known for dedicated appliances for WAN connectivity have in the recent past started to concentrate more on offering cloud-based WAN as the way of responding to this particular new trend. But when seeking SD-WAN services from the providers, you need to be particular and if need be question several aspects revolving around the services that they provide. The reason for this is that such companies offer two options to have MPLS in place and hence pay a premium for business-grade private connectivity or otherwise rely wholesomely on the public internet. Then again, it should be known that the first option is not economical since when it gets to cloud services adoption, the first choice seems to be thoroughly limiting. Nevertheless, the second choice is even more inconsistent. It is somewhat difficult to get or expect a consistent and reliable application if you are unable to skip from one glutted public network to the other. Regardless of how you route your traffic over the public network, there are high chances that you will suffer from performance hitches. Most of the SD-WAN companies are never honest with their clientele. They hide too much information for fear of losing the customers hence making it difficult for the customers to detect any problem concerning public networking and interconnectivity. But on a positive note, it is expected that what started as a simple data-center and branch –office WAN connection solution will accelerate over the next few coming years. And the better part is that this trend will expand into a broad range of SD-WAN offerings and technologies. This would include, WAN optimization, NaaS, VPN security among others. Also, the demand for high bandwidth application is increasing hence making it possible for more content to migrate to the cloud which also makes the service delivery to hoist the need for one key network that would be able to connect to accelerate it all. Essentially, what this suggests to the enterprises is that in as much as everyone is insisting for more bandwidth, SD-WAN is possibly providing the better alternative solution.
