云服务可视化编排秒杀

# 秒杀活动开始时的处理逻辑
def start_seckill():
    # 初始化资源
    setup_resources()
    # 启动监控
    monitor_system()

# 处理秒杀请求
def handle_seckill_request(user_id, product_id):
    if is_within_time_window() and is_product_available(product_id):

            try:
                reduce_stock(product_id)  # 减少库存
                create_order(user_id, product_id)  # 创建订单
            finally:
                release_lock(product_id)  # 释放锁
        else:
            return "系统繁忙，请稍后再试"
    else:
        return "秒杀已结束或商品已售罄"

# 监控系统状态

        time.sleep(10)  # 每10秒检查一次
