The Downsides to Consider with SD-WAN
Software-Defined Wide Area Networks, or SD-WANs, are increasingly popular ways to provide a combination of different transport services to enterprise users. The underlying technology that makes SD-WANs possible is uncoupling the network services from the application the enterprise is looking to use. Enterprises can use MPLS, LTE or broadband to connect users with applications they need across their large network.
As dynamic and powerful as SD-WANs are, there are some shortcomings to consider. Depending on the implementation an organization is looking for, these inherent weaknesses can spell the end of talks about SD-WAN.
First, SD-WAN requires devices to be installed on each side of a connection — that can make the technology poorly suited for cloud-based enterprises, since getting access to a cloud provider’s datacenter can be challenging. Second, SD-WAN architecture means it lacks integrated branch security — this can be circumvented with third-party security, but that can be costly. Last, its reliance on public internet can lead to outages, delays or poor routing.
Although significant, for many organizations, these aren’t sufficient downsides to torpedo the use of SD-WAN.
