Kindly suggest me the workaround and If i need to upgrade , can I do that with same instance or new instance needs to be created.

Answer 1

由于您的应用已经在运行且用户正在连接它，因此您不希望执行以下过程：

1. 关闭VM实例，保留启动盘和其他磁盘
2. 使用步骤（1）中的启动盘
启动功能更强大的实例
3. 附加并安装任何其他磁盘（如果适用）

相反，您可能希望执行以下操作：

1. 使用类似的软件/配置创建其他VM实例
2. 创建负载均衡器并将原始VM和新VM作为后端添加到
3. 将您的DNS名称更改为指向负载均衡器IP而不是原始VM实例

现在，您的用户将被随机发送到负载最少的虚拟机以查看应用程序，如果流量增加，您可以添加更多虚拟机。

您没有详细描述您的应用程序，因此不清楚每个VM是否具有本地状态（例如，运行数据库）还是外部运行的数据库。您仍然需要弄清楚如何管理来自所有VM实例的有状态系统，例如数据库或用户上传的数据，如果您的任务中的信息很少，很难提供建议。

I don't know anything about google-compute-engine(s) but maybe this will help: Here is a small explanation about instances:

https://cloud.google.com/compute/docs/instances/

And here is a link to the Google Compute Engine page:

Or maybe this will help you with increasing the cpu:

how can I increase cpu quota on google compute engine

If all those links aren't helping then I suggest to upgrade it. (Because I've never heard of Google Compute Engine I don't know if you should use the same instance or a new one.)
