At what stage in the CI/CD process is the infrastructure necessary for deploying the application configured?

Setting up the infrastructure for deploying an application usually occurs during the Provisioning or Infrastructure as Code (IaC) phase in the CI/CD process.

This stage involves automatically creating and configuring servers, network resources, databases, and other components necessary for the application's operation. It is typically performed before the build and code deployment stages.

In CI/CD tools (such as Jenkins, GitLab CI, GitHub Actions), this stage can be implemented through separate tasks that run scripts or use infrastructure management tools (Terraform, Ansible, CloudFormation).

Thus, the infrastructure is prepared in advance so that the subsequent deployment stage can correctly deploy and run the application in the required environment.
