When is Terraform good. Ansible can seamlessly provision cloud platforms, servers, hosts, and hypervisors. Therefore, Terraform always emphasizes on maintaining a particular state of the environment. These tools help DevOps create, scale, and manage server configurations with ease. Packaging and templating also differs between Ansible and Terraform. You can assume Terraform as an infrastructure provisioning tool that communicates with VMware, AWS, GCP, and ensures infrastructure deployment. You give the tool some instructions, and the tool makes something happen out there in the infrastructure. Moreover, Ansible provisioning helps users employ the universal automation language consistently across orchestration, application deployment, and configuration management. The only drawback is that as Terraform is declarative in nature, the final result is accessible only to providers. If you need an IAM user or S3 bucket, Terraform can create it.

The purpose of IaC is to simplify the process of large-scale management of infrastructure. Ansible is also capable of better orchestration for complex IT tasks such as zero downtime rolling updates and continuous deployments. Modern IaC tools simplify the configuration to resolve server problems quickly. However, the definition of procedural and declarative categories is very brief, and many tools fulfill the requirements of both. The procedural category involves a tool that is like a conductor demanding 5 guitars only to get five more guitars. Vagrant is a tool focused for managing development environments and Terraform is a tool for building infrastructure.
