How do you organize deployment of infrastructure using multiple virtual machines?

To organize the deployment of infrastructure with multiple virtual machines, Infrastructure as Code (IaC) is usually used. This allows describing the configuration of all virtual machines and their relationships in the form of code, ensuring repeatability and automation.

Popular tools for this are Terraform, Ansible, CloudFormation (for AWS), and others. For example, with Terraform, you can describe several virtual machines, their network settings, disks, and more, and then deploy the entire infrastructure with a single command.

An example of a simplified Terraform configuration for two virtual machines (pseudocode):

resource "aws_instance" "vm1" {
  ami           = "ami-123456"
  instance_type = "t2.micro"
}

resource "aws_instance" "vm2" {
  ami           = "ami-123456"
  instance_type = "t2.micro"
}

It is also important to use configuration management systems (Ansible, Puppet, Chef) to configure software on these virtual machines after their creation.

Thus, deployment becomes automatic, reproducible, and manageable.
