Configuring cloud-based environments is complex, as it requires considering networking, subscriptions, services, and all the components that make up the underlying infrastructure. Manual setup is error-prone, inconsistent, and difficult to reproduce.This tutorial shows how to set up a fully automated cloud environment using GitLab as the main operations brain. All the cloud infrastructure is defined as code (hosted on GitLab) and deployed on AWS with OpenTofu through GitLab CI/CD pipelines. On top of this, these pipelines also handle the build and deployment of a real web application, using GitOps practices with Argo CD.Why infrastructure as code and GitOps?First, it is important to understand why infrastructure as code (IaC) and GitOps matter, and how GitLab brings these practices together in a single platform.IaC ensures environments are:Reproducible: The same configuration can be deployed anywhere.Versioned: Every change is tracked in a Version Control System (VCS), with Git as the primary choice.Automated: No human interaction needed.GitOps extends these principles into the application lifecycle. Instead of manually applying changes to Kubernetes clusters (or other infrastructure), the desired state of applications lives in Git. A GitOps operator like Argo CD continuously ensures the cluster reflects what is in the repository. This brings:Consistency between environmentsFaster recovery with rollbacks that are as simple as reverting a commitBetter collaboration because teams can review and approve changes via merge requestsIncreased security through deployments that are …
