Example: Writing a Terraform configuration to provision a virtual network, subnets, and an EC2 instance on AWS.

Code Snippet (Terraform):

resource "aws_instance" "web" {
  ami           = "ami-0abcdef1234567890"
  instance_type = "t2.micro"
  tags = {
    Name = "HelloWorld"
  }
}

11. Configuration Management (Ansible)

Tools like Ansible, Chef, and Puppet automate the configuration of servers and applications. They ensure consistency across your fleet and simplify server setup and maintenance.

Example: Using Ansible playbooks to install Nginx, configure its settings, and start the service on a fleet of web servers.
Action Item: Write a simple Ansible playbook to install a package on a local virtual machine.
