Software-Defined Wide Area Network (SD-WAN) is changing the way we think of networking today. SD-WAN’s networking infrastructure is bridging the gap between the needs of today and the requirements of the future. But, how much do we know about it, how can it transform an organisation’s IT ecosystem, and what are the benefits? Here our Network Architects share their insights and answer some of these commonly asked questions.
SD-WAN is a new approach to deploying and managing enterprise WAN. It is entirely software managed (software-defined). It is an overlay technology which makes the customer network agnostic of the underlying infrastructure. It allows customers to manage their network independently of a service provider, which is unlike the existing MPLS.
There are three critical components in SD-WAN. First, the orchestrator or online portal, where all setup configurations and policies are defined. Secondly, there are branch or site gateways, which could be hardware or software appliances. Thirdly, depending on how agnostic the vendor is, there are cloud gateways or a gateway serviced by a selected vendor.
There are five key reasons why organisations should invest in SD-WAN, including:
If organisations have the right architecture, SD-WAN can be seamlessly integrated, regardless of the service or configuration of it's supporting network vendor, and reap many benefits including;
To achieve a smooth transition to SD-WAN without it affecting the performance of its current IT environment, there are several pre-engagement activities which need to be completed. Below is the checklist which all organisations should follow;
