Use Cases and Deployment Scope

I have been using GNS3 for more than 4 years, and it is a really useful program. With GNS3, we can create practical labs with all of their contents of routers, switches, wired, and wireless communication devices, all without incurring any costs, which is great. This product is special because it solved a problem at work, namely, linking physical devices to virtual devices within the program.

Pros and Cons

The possibility of applying integrated labs that simulate reality by more than 90%.
It enables the addition of different network devices from all vendors with the possibility of integration between them.

In my opinion, the program consumes a lot of device resources, especially when using the iOS version.
The program does not contain network devices, so you need to search for the network devices that you need and add them manually.

Likelihood to Recommend

If you want to design a network that contains devices from different vendors and you want to implement and monitor this network and make sure of the stability of this network before actually implementing it physically, then this is the right program. It allows you to design a complete network with different components and from different vendors with the possibility of integrating various devices and also linking them with network monitoring programs.
