Infrastructure as Code (IaC) has revolutionized how we manage and provision IT infrastructure. Gone are the days of manual configurations and snowflake servers. With IaC, your infrastructure is defined in code, bringing consistency, repeatability, and version control to your operations. Among the powerful tools in the IaC landscape, Ansible stands out for its simplicity, agentless architecture, and human-readable YAML syntax.
Ansible empowers you to automate everything from simple configuration tasks to complex multi-tier application deployments. But mastering Ansible, especially for advanced IaC patterns, requires diving into various aspects: best practices, security, performance, effective testing, and handling dynamic environments.
To help you on your journey to becoming an Ansible IaC maestro, I've curated a list of over 15 must-have resources. These aren't just basic tutorials; they're deep dives, practical guides, and community hubs that will elevate your Ansible game.
