Next Steps for PowerShell CodersVester:Vester is a community project that aims to provide an extremely light-weight approach to vSphere configuration management using Pester and PowerCLI. The end-state configuration for each vSphere component, such as clusters and hosts, are abstracted into a simple config file. The configuration is tested and optionally remediated when drift is identified. The entire project is written in PowerShell.
https://github.com/WahlNetwork/Vester
Next Steps for Python CodersAnsible:Ansible is a radically simple IT automation platform that makes your applications and systems easier to deploy. Avoid writing scripts or custom code to deploy and update your applications— automate in a language that approaches plain English, using SSH, with no agents to install on remote systems. http://ansible.com/
