A network operations team is using the cloud to automate some of their managed customer and branch locations. They require that all of their tooling be ephemeral by design and that the entire automation environment can be recreated without manual commands. Automation code and configuration state will be stored in git for change control and versioning. The engineering high-level plan is to use VMs in a cloud-provider environment, then configure open source tooling onto these VMs to poll, test, and configure the remote devices, as well as deploy the tooling itself.
Which configuration management and/or automation tooling is needed for this solution?
