Open-source DevOps tools are used to deploy applications and services in datacenter server networks, but they may also enable researchers or students to simulate networks. In this post, we will survey popular open-source DevOps tools and provide links to information that shows how to use them to create network simulation scenarios.
Most open-source network simulators simplify the setup and configuration of virtual machines and the networking connections between virtual machines. DevOps tools such as OpenStack do the same things, although they expose more of the complexities of the virtualized infrastructure to the user.
If you are already using DevOps tools for other activities you may find it useful to also use them when you need to create a simulated network instead of learning to use a network simulator.
