A Complete Insight on Software-Defined WAN

798Views

Organizations have relied on various forms of routing their applications and services to users. These forms of routing traffic are like the Multi-Protocol Label Switching (MPLS). With this technology, data transfer to an organization’s branch is fast, and network traffic is minimized.

Organizations use Wide Area Network to get information to their various branches and clients. The Software-Defined Wide Area Network has revolutionized data transporting technologies. SD-WAN eliminates the need for traditional routers to transmit services to clients and branches. Installing this architecture reduces the costs of broadcasting the internet. This reduction in cost is because SD-WAN can work with the existing MPLS or replace it with regular connectivity.

Therefore, it is important to understand SD WAN management. Organizations will be able to run their systems with ease.

How Do I Manage a Software-Defined Wide Area Network?

 There are two ways of managing SD-WAN. These ways of SD-WAN management are SaaS and managed SD-WAN. Once an organization has decided to implement this architecture in its system, it can use one of these managing techniques.

SaaS stands for software as a service. You can manage your SD-WAN as a service. A third-party provider will provide this software to customers over a network.

The customer is responsible for managing and changing the wide-area network at will. The provider allows the user to access the latest version of SD-WAN. Customers (organizations) will pay for the upgraded version.

The provider offers several features to the user to improve their application performance. For example, Apcela is an “as a service” SD-WAN provider. Their features include cloud optimization and integrated security.

Other features offered by SaaS providers include cost reduction, application awareness, and zero-touch provisioning.

Some of these service providers offer private WAN connectivity, while others offer services that can be used with different vendors.

Managed SD-WAN is where an organization outsources network applications and services. This outsource is done through a managed service provider or communications service provider.

Unlike the SaaS, managed SD-WAN providers monitor, secure, and change the network service. The service provider runs all the programs, and the organization is relieved of this function.

Payment is usually made annually. Pricing usually depends on the number of branches that need to be linked and their locations. The service level agreements and link speed also determine the price of managed SD-WAN services.

These methods depend on the organization’s decision. Either of these methods has its own benefits, and the incentive to choose one is up to the company.

What Are the Available Types of SD-WAN Architecture?

There are three basic types of SD Wide Area Network architecture. The organization has to analyze the pros and cons of each architecture before making a decision to install it.

The premises-based SD-WAN architecture is where hardware is mounted on site. The required appliances are physically installed in the organization.

The MPLS architecture is where several appliances are installed in network endpoints. This architecture is a virtual network between the various hardware.

The internet-based SD-WAN architecture is where hardware is installed at each client’s location. Regardless of the architecture chosen, each of these types has a complete range of functionality.
