Eliminating Cloud Console ClickOps
Configuring cloud resources (virtual machines, VPCs, firewall rules, and managed databases) by clicking through web consoles is error-prone, undocumented, and irreproducible. When disaster strikes, reconstructing an entire environment from memory is a nightmare.
Infrastructure as Code (IaC) treats cloud infrastructure with the exact same rigor as application source code: version-controlled, peer-reviewed, tested, and automatically deployed.
1. Declarative Cloud Provisioning with Terraform
Terraform allows engineers to declare the desired end-state of cloud resources in HCL (HashiCorp Configuration Language). Terraform calculates the execution diff (terraform plan) and applies only the required changes idempotently.
2. Configuration Management with Ansible
While Terraform excels at provisioning infrastructure hardware (VM instances, storage buckets), Ansible excels at configuring what runs on those servers (installing security patches, hardening SSH daemons, and setting up systemd services) over agentless SSH connections.
