Ansible is a super-simple automation platform that is agentless and extensible. The network community continues to rally around Ansible as a platform that can be used for network automation tasks that range from configuration management to data collection and reporting. You can push full configuration files with Ansible, configure specific network resources with idempotent modules such as interfaces or VLANs, or simply just automate the collection of information such as neighbors, serial numbers, uptime, and interface stats, and customize reports as you need them.
Because of its architecture, Ansible proves to be a great tool available here and now that helps bridge the gap from legacy CLI/SNMP network device automation to modern API-driven automation.
Ansible’s ease of use and agentless architecture accounts for the platform’s increasing following within the networking community. Again, this makes it possible to automate devices without APIs (CLI/SNMP); devices that have modern APIs, including standalone switches, routers, and Layer 4-7 service appliances; and even those software-defined networking (SDN) controllers that offer RESTful APIs.
There is no device left behind when using Ansible for network automation.
