DevOps style configuration management for the network with Open Source

Season 1, Talk 4 of NetDevOps Live! Stuart Clark provides an introduction and overview of the open source configuration management tools for networking. The similarities and differences of Ansible, Puppet, Chef, and SaltStack are explored, and a demo (including live troubleshooting) is given.

Many enterprises are leveraging Open Source tools like Ansible, Salt, Chef or Puppet to manage the configurations across their servers and application systems, and looking to extend the use into the network. The goal is to interact with network devices via abstraction and automated framework and avoid the pitfalls of "Finger Defined Networking." Scripts are a great first step to automation, but they require maintenance and strong programming skills. Configuration Management tools like Ansible are powerful automation and orchestration frameworks maintained by the Open Source community. With them you provide the configuration "intent" in a simple and consistent fashion, and the details of implementation are handled by the tooling. In this session we will explore how the same tools system admins are using to manage servers, cloud and applications can be leveraged in the network to foster a DevOps culture across silos in the organization.
