But if your application is not inherently scalable, the cloud won't help you.
In fact, strictly speaking, scalability is a property of the application, and it means that the application starts supporting higher load by simply adding hardware. The cloud offers you the "adding hardware" part. The rest is your responsibility.
Now, how to achieve scalability of your application is a huge topic. High scalability is a good resource for such articles.

可扩展性的关键不仅仅是基础设施。您可以使用各种云产品：
但是如果您应用程序本质上不具有可扩展性，云不会帮助您。
事实上，严格来说，可扩展性是应用程序的一个属性，它意味着应用程序通过简单地添加硬件就开始支持更高的负载。云为您提供“添加硬件”部分。剩下的就是你的责任了。
现在，如何实现应用程序的可扩展性是一个巨大的话题。 高可扩展性是此类文章的良好资源。
The key to scalability is not the infrastructure (only). You can use various cloud offers:

现在 Heroku 支持 Java。服务/价格都很超值:)
Now Heroku supports Java. Great value for service/price :)
查看 Google App Engine。对于您的情况，App Engine Java 概述会很有帮助。您还可以使用 Python 构建 App Engine 应用。
Take a look at Google App Engine. In your case, the App Engine Java Overview will be helpful. You can also build App Engine applications using Python.
Google App Engine 执行此操作。它也是全部 Java 和 Javascript（需要时从 Java 转换）。
Google App Engine does this. It's all Java and Javascript (converted from Java when needed) too.
