GNS3 allows you to run a small topology consisting of only a few devices on your laptop, to those that have many devices hosted on multiple servers or even hosted in the cloud.
Architecture GNS3 consists of two software components the GNS3-all-in-one software GUI client and the server. When you create topologies in GNS3 GUI client the created device need to run on the server. The ser ver can be a local GNS3 server in a GNS3 VM or on a Remote host.
