What is SD WAN? – Definition,Benefits, Deployment and Vendors

If you’re the owner of a modern business that is spread out across several geographic locations, you’ve probably come across the term SD-WAN on several occasions while looking at the various ways to handle your internal online interactions.
What is SD-WAN and why businesses use SD-WAN systems in modern technology? Here’s everything you need to know about utilizing the facility in 2019 and beyond.

What is SD-WAN?

The term SD-WAN is an acronym that stands for Software-Defined Wide-Area Network. It is a term that relates to SDN(Software-Defined Networking) and is something that is used by thousands of companies across the country and further afield as they look to connect different parts of their business to a wireless network.
This is achieved via the application of SDN technologies to WAN connections. Examples of WAN connections include broadband connections, 4G, and LTE. The function is to connect the various business premises to the same, secure network through the internet or a cloud-native private network.

The use of the SD-WAN system is, therefore, an upgrade from outdated computer network frameworks of the past as they are detached from traffic management and hardware-based monitoring functions. Instead, it is built upon; Edge Connectivity Abstraction, WAN Virtualization, Centralized Management, and Elastic Traffic Management.

A software-defined wide area network can be used in favour of T1, MPLS, and other traditional WAN systems, although over three in four companies still persist with the old facilities in conjunction with their SD-WAN networks.

Why SD-WAN?

Before incorporating SD-WAN networking solutions into your business operation, it’s imperative that you learn to appreciate the reasons for potentially doing so. Only then can you make a calculated decision as to whether the deployment is right for you.

Companies that have persisted with traditional WAN architectures should see this as the perfect time to make a switch as they simply cannot match the performance of the modern SD-WAN upgrades. The advanced networks outperform the old ones in virtually every way covering bandwidth, security, cost, and reliability. For similar reasons, new ventures should only ever consider SD-WAN. Otherwise, the entire business is at a disadvantage from the start.

SD-WAN network solutions bring many benefits to the table including optimizing cloud and on-premises application performance with real-time analytics, along with maximum choice and control. If the business isn’t using SD-WAN, it isn’t reaching its full potential.

Fact is that the need for perfect internal communication and online facilities is no longer limited to the IT sectors. Virtually all business rely heavily on computer tech while a growing number require perfect communications between different endpoints and geographic locations. As such, SD-WAN isn’t merely a nice addition. It’s an essential feature in for a battle in the fierce world of modern business.

What are the benefits of SD-WAN?

Utilizing SD-WAN can transform a company’s approach to online performance, communication, collaboration, and application. SD-WANs are there to support connectivity between different branches and can be used across offices, shops, and other working environments with easy implementation and ongoing management.

SD-WAN offers a centralized, cloud-based deliverance that is particularly useful for companies that use applications that reside in the cloud. The scalability opportunities and automated deployment possibilities can be used across thousands of endpoints in a seamless fashion. Aside from improving the deployment process, this creates a better framework for ongoing analysis.

Security is another priority for modern businesses to consider. The implementation of SD-WANs removes the need for data to keep traveling back to the data centers as the security features are present at each endpoint. The data encryption and advanced threat intelligence systems ensure that users, devices, and applications remain safe at all times.

The user experience across the network is greatly improved for several reasons. The deployment of SD-WAN systems that actively divert users when traffic-related issues surface can save a lot of valuable time and prevent huge levels of stress. This dynamic approach overcomes link degradation among a variety of other problems. Crucially, the collaboration opportunities which allow for modifications to be automatically synced across the board create a far better operation.

As with any key business decision, one of the main issues revolves around the value for money. SD-WAN solutions offer a cost-effective upgrade for many reasons. The function and scalability are naturally key features, but licensing should not be overlooked either. Meanwhile, it offers the opportunity to lose expensive MPLS connections in favour of VPNs and other economic broadband services.

SD-WANs can incorporate the popular Office 365, Salesforce, and major SaaS applications in addition to optimized workflows such as AWS and Azure. The smooth operational flow is supported by responsive performance reporting, allowing for any adjustments to be made without any problems.

How to deploy SD-WAN

There are many companies who manufacture SD-WAN products, and every product has a different installation guide. As such, it can all get a little confusing and overwhelming. This is why you should seek external support.

The best solution to deploy SD-WAN is to hire an SD-WAN Engineers from FieldEngineer.com which is a Hub of SD-WAN Engineers of all manufacturers.

SD-WAN Vendors
