Terraform
Netris operated on-prem clouds can be provisioned and managed using Terraform. The entire network environment can be managed as a repository or a CI/CD pipeline of Terraform HCL (Hashicorp Configuration Language) files, simplifying deployment and ongoing changes of your data center and cloud networks.
Use Terraform with Netris just like in the public cloud
With legacy systems, you will need to describe specific details for every network device and ensure there are no conflicting configurations across historically crafted configs throughout the entire network. (pets approach)
With Netris, you only need to declare high-level services for the Netris controller, and Netris takes care of all the configurations automatically. (cattle approach)
