Infrastructure
infrastructureInfrastructure covers how systems are provisioned, connected, and operated — from infrastructure as code and networking to architecture patterns that balance reliability, cost, and simplicity. These guides favor repeatable, reviewable approaches over manual, one-off changes.
Topics span Terraform and configuration management, cloud architecture, observability, and the operational patterns that keep platforms dependable as they grow.
Frequently asked questions
What is infrastructure as code?
Infrastructure as code (IaC) means defining servers, networks, and services in version-controlled configuration files rather than clicking through consoles. Tools like Terraform and Ansible then create that infrastructure reproducibly, making changes reviewable and auditable.
What is the difference between Terraform and Ansible?
Terraform provisions infrastructure (declaratively creating resources and tracking their state), while Ansible focuses on configuration management (setting up and configuring existing machines). Many teams use both together.
