Question 1

Ansible vs Terraform, when do I use each?

Accepted Answer

Ansible: configuration management, application deployment, orchestration. Iterative, mutable infrastructure. Terraform: infrastructure provisioning, immutable desired state, AWS/Azure/GCP resource management. Modern DevOps uses both: Terraform provisions instances, Ansible configures them. They complement, not compete.

Question 2

How is Ansible agentless different?

Accepted Answer

Ansible connects via SSH (Linux) or WinRM (Windows), no agent to install, no background service running. Competitors (Puppet, Chef) install agents that phone home. Agentless = less operational overhead, easier onboarding, better security (no persistent agent). Trade-off: slightly slower for massive-scale ops (100k+ nodes).

Question 3

What's idempotency and why does it matter?

Accepted Answer

Running a playbook twice = same result as running it once. If a package is installed, re-running doesn't reinstall. If a config file is correct, no change. Idempotency = safe automation; ops can re-run playbooks without breaking production. Ansible modules are idempotent by design.

Question 4

Ansible Tower vs AWX vs Ansible Automation Platform, what's the difference?

Accepted Answer

AWX (open-source, free, community-supported): UI, RBAC, scheduling, webhooks. Tower (legacy, deprecated): commercial, replaced by AAP. Ansible Automation Platform (AAP, modern): Red Hat's commercial offering with support, advanced analytics, hub integration. For enterprises: AAP. For labs/small orgs: AWX. AWX is fine for most use cases.

Question 5

How do I manage secrets in Ansible?

Accepted Answer

Ansible Vault encrypts sensitive data (passwords, API keys) in playbooks. Store vault password in `.vault_password` file or pass via `--vault-password-file`. For teams: use HashiCorp Vault integration. Never commit secrets to Git; use CI/CD to inject at runtime.

Question 6

What's the difference between plays, tasks, handlers, and roles?

Accepted Answer

Play: collection of tasks targeting a host group. Task: single action (install package, restart service). Handler: task triggered by notify (only runs if something changed). Role: reusable, organized bundle of tasks, handlers, templates, variables. Roles = best practice for scaling.

Question 7

Can Ansible manage cloud infrastructure like AWS?

Accepted Answer

Yes, via modules: aws_ec2, rds, s3, etc. Ansible provisioning < Terraform (Terraform is cloud-native). Use Ansible for post-deployment config, app setup. Use Terraform for resource provisioning. Together: Terraform spins up, Ansible configures.
