What approach is used in preparing the infrastructure for application deployment?

When preparing infrastructure for application deployment, the Infrastructure as Code (IaC) approach is usually used. This means that all infrastructure is described in the form of code, which can be versioned, tested, and reused.

Main steps:

• Requirements definition — what resources are needed (servers, databases, networks).
• Writing configurations — using tools like Terraform, Ansible, CloudFormation.
• Automated deployment — running scripts or pipelines that create and configure the infrastructure.
• Testing and validation — ensuring the infrastructure meets the requirements.
• Monitoring and support — ensuring stable operation and updates.

This approach allows for quick and reliable creation of environments for applications, minimizing errors and ensuring repeatability.
