This also depends on your scale. If you have lots of routers, you would end up with lots of compute to run the VM instances. If you get the compute (which is cheap comparing to actual network hardware), you would need a "cloud orchestration” tool and a a system to connections from host to host like some form of overlay networking. GNS3 would do a good job, but for something with a bit more orchestration APIs. There is this: https://networkop.co.uk/post/2019-01-k8s-vrnetlab/ <https://networkop.co.uk/post/2019-01-k8s-vrnetlab/> And the nice people who even show up to NANOG every once in a while: https://www.tesuto.com/ <https://www.tesuto.com/> There are a few other tools that people built on their own if you scrub GitHub. I even felt into that trap and exploring VRnetlab. But numerous things were achieved. Yes, you would miss out on all the hardware bugs, hardware adaption layer issues and maybe a scale issue or two, but with enough instances, route generators and maybe even some application (some of these things can even forward traffic), you could discover 90% of things that can go wrong. And you get the flexibility of downloading evaluation images of all kinds of things, so maybe you can avoid spending any money.

The key it keeping its all up todate down to the firmware version (I know its not possible for some because virtual) The things this wont find are hardware related faults or issues.

Has anyone here tried this before to any success? We need to buy the Cisco IOSv image to continue with the sim so I figured I would inquire here first before diving in.
