Do you remember the times when the basic tool of the trade was a desktop computer and the one and only software dedicated to your organisation? We can reminisce about this simple model, which also translated into the level of complexity of the IT infrastructure, with nostalgia. It consisted of only a few databases. Users and applications used only one unified MPLS network.
These peaceful times are a thing of the past. Due to the high mobility of employees, it is necessary to provide them with access to IT resources from anywhere in the world. This is not the only challenge for a company’s network infrastructure. We can count on the fingers of one hand the professions which at the moment use only one tool. Your employees use many applications- both cloud and local- to complete their tasks. In order for their work to go undisturbed, they need reliable network performance.
How to deal with new network management challenges?
New expectations and challenges mean that the solutions used so far are no longer an effective fix. The traditional MPLS networks that are currently used generate high costs. Managing them also takes a lot of time. The reason for this is the fact that their operational models are based on assumptions adopted over 15 years ago. It was not predicted then that the IT infrastructure specialists would soon have to react dynamically to changes happening every few days!
Considering all the problems that modern companies have to face, the need to implement a new approach is clear. The use of SD-WAN technology seems particularly attractive in this case.
What is SD-WAN all about?
In short, it is about controlling the network with the use of an uncomplicated management center. An advantage of SD-WAN is the possibility of quick reaction and readiness to introduce instant performance-related changes and deliver applications.
Software-defined networking (SD-WAN) means more flexible traffic management and the implementation of network services from one location. It is worth illustrating this on the example of the Ipanema solution.
Ipanema automatically identifies applications that are part of the network. Then, it groups them into categories, analyses performance and establishes priorities on the basis of their importance to the functioning of an enterprise. In the next step, Ipanema adjusts performance to predefined goals and provides the best possible application performance based on its criticality.
In practice, this helps IT departments significantly optimise the functioning of the corporate network with a small amount of effort. Just imagine a situation where it is necessary to carry out an important teleconference in a company. The future of profitable projects may depend on its success. In this case, it is possible to automatically reroute such network traffic to the network with the highest bandwidth. An important feature is also the option of separating the network traffic generated by employees, as well as that generated by customers or partners. All these aspects can be under the control of the IT department in one place, which facilitates the introduction and management of any changes.
It is worth noting that in the coming years, a dynamic growth in the use of SD-WAN technology is expected. IDC forecasts annual growth rates of 69%. Gartner is slightly more cautious and provided a forecast of annual growth rates at the level of 59% in their report.
