Learning Ansible

Automation includes provisioning new servers, making sure the servers adhere to their role and maintain the desired state from a configuration perspective, and orchestrating various actions across environments and deploying code as expected to all these servers. This is where Ansible steps in. It is secure, highly reliable, and minimalistic in nature. It automates configuration management, application deployment, and many other IT needs. Learning Ansible will equip you with the necessary skills to automate/improve your infrastructure from a configuration management perspective. You will also be able to use Ansible for one-click deployments, provisioning, and orchestrating your infrastructure.
