案例1：跨可用区容灾部署

# disaster_recovery.yml
- name: Configure cross-AZ disaster recovery
  hosts: cloud_servers
  vars:
    primary_az: "az1"
    backup_az: "az2"
  tasks:
    - name: Create ECS instances in backup AZ
      ctyun_ecs:
        name: "dr-{{ inventory_hostname }}"
        az: "{{ backup_az }}"
        image: "CentOS-7.9"
        specs: "2C4G"
        state: present
      register: dr_instances

    - name: Sync configuration
      ansible.builtin.synchronize:
        src: "/etc/nginx/"
        dest: "/etc/nginx/"
        delegate_to: "{{ item.public_ip }}"
      loop: "{{ dr_instances.results }}"
            

案例2：自动扩缩容策略
