There are three main types of SD-Wan Systems. These are the DIY (do-it-yourself) model, Carrier-managed SD-WAN services, and OTT (over-the-top) systems. This article will look at both options and how they work. Learn about it below.

Do-it-yourself (DIY) model

The choice between a DIY and managed SD-Wan solution can be confusing. The first implies that a company handles all aspects of the network, while the latter means that an IT team oversees the implementation and management of the SD-WAN. Both approaches have advantages and disadvantages, and companies should understand what suits their business needs before deciding on a solution. In addition to a managed SD-WAN solution, DIY sd-wan systems will likely require extensive IT management expertise.

A DIY SD-WAN system provides the advantages of being self-configuring and can eliminate the need for managed services. However, it has some significant drawbacks. For one, it requires specific technical skills and a lengthy sales cycle. Furthermore, it can be challenging to deploy SD-WAN systems. A managed SD-WAN service provider can perform the necessary tasks but is not as flexible as a DIY model.

An SDC can also offer a host of other benefits. For example, SD-WAN systems often run on Tier-1 IP backbones with service-level agreements attached. Additionally, these providers have better security and performance standards. While a DIY model of SD-Wan can work, it also increases the potential for human error. A managed service provider can provide more services and resources than a DIY model, but it will probably have fewer staff with technical experience.

Carrier-managed SD-WAN services

What is a carrier-managed SD-WAN service? Simply put, it’s a carrier-grade SD-WAN service managed by a network operator. This service delivers dynamic customer edge site connectivity while providing centralized network control and end-to-end visibility. In most cases, this solution is a hybrid service. Regardless of how it is implemented, both types of SD-WAN solutions offer unique benefits. While both models can be advantageous in some circumstances, choosing one over the other may make the most sense for your organization.

The top six carriers have made many moves over the last year to get into this space. One page has dropped out of the top five spots; however, it’s still in the lead and will have two percent of SD-WAN customer sites in the U.S. by 2021. In the same year, the number of respondents shifted from one carrier to another. One survey showed that 25% of respondents closed up to 50 percent of their office locations and planned to make at least a quarter of their workforce permanently. Similarly, 51% of respondents said they’ll eliminate their legacy data centers within 24 months.

Carriers are releasing year-end LEADERBOARDs based on the number of customer sites they have deployed. The top seven companies are Aryaka, Colt, Global Cloud Xchange, Lumen, PCCW Global, Tata, Telia, and Telstra. The company with the most installed customer sites is Aryaka. A carrier-agnostic managed SD-WAN services also offer a free proof-of-concept solution.

OTT (over-the-top) model

The OTT (over-the-top) SD-Wan model enables enterprises to select the network provider that provides the best performance at a given location. It also allows dual-homed and diversely routed circuits. However, the OTT model poses several problems for enterprises that are dependent on professional-grade communications and depend on high-speed internet. Users must periodically test their communications equipment to ensure the OTT model is performing as expected.

For medium-sized IT organizations, the co-managed SD-WAN service by Masergy is a viable option. It is also a good choice for those looking to migrate to SD-WAN. However, it comes with a slightly higher price tag than its competitors. The downside of the co-managed SD-WAN service is its high cost. But, if you can’t wait to deploy SD-WAN, it’s a good choice.

The OTT model has many advantages. First, it allows users to use their current Internet connection to access the SD-WAN service. Secondly, it eliminates the need for expensive cable TV and landline phone service. Furthermore, users can view the content directly from third-party content providers. Finally, OTT allows businesses to customize their networks and control costs. This is especially advantageous for small and medium-sized enterprises.
