Essential Infrastructure as Code teaches patterns for scaling systems and supporting infrastructure for mission-critical applications. The book isfull of flexible automation techniques that work whether you're managing your personal projects or making live network changes across a large enterprise.

You'll go hands-on to build networks, servers, load balancers, and firewalls using Python and Terraform. Learn how to confidently update infrastructure while your software is running, migrate existing legacy systemsto IaC, and implement team-wide norms that avoid instability and security problems. The universal principles you'll find within are easy to apply toalmost any use case, from data centers, to public cloud, to Software-as-a-Service.

Infrastructure as Code (IaC) replaces time-consuming manual provisioning and configuration with automation via configuration managers or provisioning tools like Hashicorp Terraform. Managing your infrastructure as code makes it easy to test changes and implement new features, scale systems without downtime or operational toil, and rapidly roll back mistakes.
