SD-WAN Benefits

Benefits of SD-WAN in Australia

As time progresses, the amount of data being transferred between businesses and their locations is continuously increasing. The more data that is transferred, the greater the dependency and reliance businesses have on their wide area network (WAN) – this results in the need to regularly optimize the performance of WANs and the various systems/applications that run on them. This is where SD-WAN comes into play.

While WAN optimization solutions are being used, the advent of software-defined WAN (SD-WAN or SD WAN) technology has emerged as an ideal networking method that helps businesses and their network administrators effectively deliver the highest level of performance, in the most cost-efficient manner. Yet another benefit and pull-factor of SD-WAN is that it provides administrators with comprehensive feedback-driven visibility over their network, allowing them to determine how to improve efficiency on the go. 


Greater reliability

Many companies require the 99.99%, or four nines, reliability that only MPLS have been able to offer to date, where basic internet connections have failed since they are not four-nines reliable and are only about two nines or 99%. With the introduction of SD-WAN, many companies are making up for this by moving entirely on to SD-WANs that comprise of multiple internet connections from different providers, which helps maintain the “four nines” (99.99 percent) reliability in the case of link failure. Therefore, in the context of reliability and the availability of a network where packets reach their destination, an SD-WAN option offers the reliability a basic standalone internet connection cannot provide at a price that is more cost-effective than an MPLS network.

Define SD-WAN

So, what exactly is SD-WAN?

SD-WAN is an implementation that automates the distribution and management of a network’s resources, thereby enabling it to deliver improved performance, accelerate service delivery and improve availability – all at a relatively affordable cost.

Think of SD-WAN as a smart, living network that is constantly monitoring and measuring key network traffic data/metrics, like packet loss and latency. With this data, the network can respond proactively to instantaneous network conditions by choosing an appropriate path for each data packet. The result is the more efficient and effective utilization of a network’s resources that can adapt to the increasing traffic and meet the network demands of modern businesses.

In many instances, SD-WANs are almost always integrated into a company’s WAN – the advantage of this approach is that it will support multiprotocol label switching (MPLS) and hybrid WANs. This will enable the network to deliver significant improvements irrespective of what type of network infrastructure is currently in place.

Improved security:

With the rise of hackers and breaches of confidential corporate information on the rise, network security has become very important to businesses. A properly implemented SD-WAN can bolster overall network security by encrypting WAN traffic as it moves from one point to another. SD-WAN also allows for the segmenting of a network at the point of a breach so that if one does occur, the damage can be contained. The pre-emptive and proactive characteristics of SD-WANs can also help network administrators detect attacks faster than they would with an ordinary internet connection – given their constant visibility of network traffic.

Why WAN optimisation?

We have already answered this question to a certain extent in the sections above, however, SD-WANs are being widely adopted by various businesses largely due to the core monetary and efficiency-related benefits they add to a company’s operations. Below, we highlight four of the core benefits behind SD-WAN implementation and why we think you should consider it for your business.

Enhanced adaptability and agility:

The keyword of ensuring success in the modern business world is adaptability and agility – businesses that can maintain this philosophy across all segments of their operations, usually end up being successful. SD-WAN is all about adaptability and agility. Routers on SD-WANs can collate the bandwidth of multiple WAN connections and give companies the ability to easily add or remove WAN connections whenever they need to, making them better prepared for the demands of shifting network traffic. SD-WAN is also very useful if you are a business that operates in multiple sites given that the technology also facilitates quick distribution of WAN services to a site without the need to send your own IT personnel to implement at the location.

Better network performance:

Since SD-WAN implementation utilizes the internet to create secure, high-performance connections, they can provide a service that does not come with the back-haul penalties associated with MPLS networks. This means that SD-WANs can support businesses better by delivering applications and services in a cost-effective manner.
