Many firms in the modern world will in most cases contemplate as to whether SD-WAN improves their Wide Area Network. In this, they will typically focus on the different types of SD-WAN architecture availed by different vendors. There are basically 3 common types of SD-WAN framework that will end up benefiting different companies. The suitability will largely be determined by the applications that are accessed by the firm through the WAN. This piece focuses on the various types of SD-WAN architecture.
An on-prem-only SD-WAN architecture will basically constitute an SD-WAN box that performs the shaping of each site in a real-time basis. The term prem, in this case, is used in the specific effort to bypass the IT industry’s heated argument regarding premise vs premises. Unlike in some other types of SD-WAN types, the WAN box will not connect to the cloud gateway as it is on-site. It will only connect to the other sites of your company. This type of architecture will be ideal for companies that are hosting their applications in-house. As such, it will fit firms that do not use cloud applications. Moreover, do not strive to utilize a cloud-based SD-WAN solution as enabling cloud will only fluctuate the costs. A recommendation here would be to keep smaller MPLS systems for real-time business applications and at the same time utilize public internet which is centrally controlled by sd-wan for everything else in the firm.
In this type of WAN framework, the solution offered is simply an on-site box that connects to a dedicated cloud gateway. When you adopt this kind of framework, the company will get benefits such as those if the on-prem architecture and at the same time, it gets boosted performance in online applications. The online gateway is usually networked to major suppliers in a direct manner. This results in an improvement in the overall performance of cloud applications. Moreover, if the firm’s WAN circuits get faulty as you use cloud applications, the gateway can maintain active cloud sessions. On the other hand, if the firm has an optional internet circuit, SD-WAN can comfortably re-route the cloud app to it. This prevents the interruption of any single session. The cloud-enabled architecture will be ideal for firms that big-name cloud applications.
Cloud-Enabled with Backbone
It is always a good idea to have a backbone at everything. Focusing on the cloud-enabled SD-WAN framework, it can be boosted a great deal by a backbone. In this, you would have an on-site SD-WAN box that connects your site to the SD-WAN provider’s nearest POP (Point of preference). Your traffic can hop on the SD-WAN provider’s private network foundation at any time. When this happens, you are guaranteed to get reduced levels of latency, jitter or even packet loss. It leads to the overall improvement in performance particularly in real-time traffic like voice, virtual desktop and video. It will be fit for companies that run loads of real-time network applications. These would have the idea of scraping off their MPLS network so as to reduce costs.
With the above insights, you will be able to choose the most ideal architecture to fit your business needs.
