Hi@akhtar,
To configure the Nginx server in AWS, you need to install the software for Nginx. After that, you can host any page in the Nginx server as shown below.
- hosts: ec2_instance_ips
  remote_user: ubuntu
  become: True
  tasks:
    - name: Install nginx
      apt:
        name: nginx
        state: present
    - name: Create default index page
      copy:
        dest: /usr/share/nginx/html/index.html
        content: "Howdy from {{ ansible_hostname }}"
    - name: Restart nginx
      service:
        name: nginx
        state: restarted
