How Can One-Size-Fits-All WANs Benefit Enterprises?

By Enterprise Networking Mag | Tuesday, January 14, 2020

Organizations are searching for the one-size-fits-all WANs that can connect multiple local area networks in case it fails while being applied to modern hybrid cloud application architectures.

FREMONT, CA: With the applications developing in data centers and public clouds, the widespread distribution of their necessary data and workloads has earned the name, which is called a hybrid cloud. The advent of hybrid cloud has made a lot of businesses rethink the architecture of network resources they used to connect the highly distributed environments due to difficulty, security, and management concerns. WAN and other legacy network technologies have never been designed to connect application components in the cloud with on-premises databases. 

Software-defined networking solutions have developed to concentrate on their requirements of applications, as opposed to users. It does that by addressing the primary technical incompatibilities, along with performance and management problems that are usually seen in legacy network connections. 

Such application-driven networks offer a software-defined perimeter, enterprise-grade availability, and the flexibility of software-defined network management. Unlike their forerunners, they are developing to be implemented faster and managed efficiently without any load of proprietary hardware vendors, as well as their old-fashioned delivery, support, and management models.

There are three significant keys to application-driven network architecture, which are: 

Application-Centric:

Applications, along with micro-services and server-less apps, can dwell anywhere on the network that serves as a connective tissue to the application components, distributed and managed across every network endpoint. The network can be taken care of as code inside of the existing DevOps methods and toolsets, in the same way how infrastructure-as-a-service is managed as code now. 

Flexible: 

The agnostic features of the network can be superimposed on top of any network infrastructure such as 4G, private circuits, ethernet, or cloud networks. Networks can be implemented anywhere in a moment by making use of a standard set of management, as well as control features. Segregation of data and control planes allows a private point-to-point application connection that has to be controlled by centralized portals throughout all environments.

Open:

Every network function, such as configuration, management, and monitoring, can be accessed via APIs. The open components help in bringing tighter integration with ecosystem partners as well.
