Introduction
Automation in a tech stack refers to using tools, scripts, or workflows that execute tasks without manual intervention. This improves reliability, speed, and consistency across development, deployment, monitoring, and infrastructure operations.
Key Areas of Automation
| Area | Purpose | Common Tools |
|---|---|---|
| Code & Build | Compile, test, package automatically | CI pipelines (GitHub Actions, GitLab CI, Jenkins) |
| Deployment | Deliver applications to servers/clusters | Ansible, Terraform, ArgoCD, Helm |
| Infrastructure | Provision VMs, networks, storage | Terraform, CloudFormation |
| Configuration | Enforce system state across servers | Ansible, Puppet, Chef |
| Monitoring | Auto-alerting & self-healing | Prometheus + Alertmanager, Grafana, systemd |
| Scripting | Automate repetitive tasks | Bash, Python |
