Cloud Infrastructure
Cloud infrastructure work covers the architecture and provisioning underneath everything else on AWS — networking, compute, and storage, and the Infrastructure-as-Code that defines it.
In practice: Terraform-defined infrastructure, Ansible for configuration management, and Packer for reproducible machine images — changes that are version-controlled and reviewable, rather than made by hand and remembered later.
Also
- DevOps Engineering — CI/CD, automation, and GitOps — making releases routine instead of risky.
- Site Reliability Engineering — Observability and reliability as measurable properties, not luck.
- Platform Engineering — The internal platform other engineers build on, standardised and self-service.
