If enterprises are considering introducing SD-WAN technology into the WAN, they should first grasp the advantages and disadvantages of different SD-WAN architectures. In recent years, with the boom of SD-WAN, there are dozens of products available for enterprises to choose from, and SD-WAN has gradually gained more and more technology drivers in the market.
In my opinion, there are three main types of SD-WAN architectures, each of which will benefit some types of companies. The best way to structure them depends on how the company accesses applications over the WAN.
1, pure local mode (On-prem-only)
On-prem-only SD-WAN, as its name suggests, companies need to maintain an SD-WAN box locally (which is essentially a plug-in router) that performs real-time traffic monitoring at each site.
Unlike other architectures, the SD-WAN box does not need to be connected to the cloud gateway, it is only connected to other endpoints in the enterprise.
The most suitable type of business: companies that host all applications within the company (without any cloud applications), if the enterprise does not use cloud applications, then you do not need to use cloud-enabled SD-WAN solutions to add cloud computing enablement Will increase unnecessary costs. A common configuration is to maintain a scaled-down MPLS network for real-time applications such as voice, video, or virtual desktops, and to effectively utilize the public Internet controlled by SD-WAN.
