Frequently Asked Questions about Terraform
What is Terraform?
Terraform is an open-source Infrastructure as Code (IaC) tool by HashiCorp that allows users to define, provision, and manage cloud and on-premises infrastructure using declarative configuration files.
What are the primary use cases for Terraform?
Provisioning cloud infrastructure (VMs, networking, storage). Managing Kubernetes clusters. Automating multi-cloud deployments. Creating modular reusable infrastructure components. Version-controlling infrastructure changes
What are the strengths of Terraform?
Consistent cross-cloud provisioning. Reproducible infrastructure with version control. Strong community support and ecosystem. Extensive provider availability. Safe change management with 'terraform plan'
What are the limitations of Terraform?
State management can become complex for large environments. Not ideal for procedural or complex runtime logic. Some providers may lag behind native APIs. Requires careful handling of secrets. Debugging resource dependencies can be challenging
