I am sure this question has been asked and answered before multiple times. 我确信这个问题已经被问过并回答过多次了。 But unfortunately, I am still not clear. 但不幸的是，我仍然不清楚。 Here is my issue. 这是我的问题。

I have a JSP, Servlet application which uses MySQL as the database. 我有一个使用MySQL作为数据库的JSP，Servlet应用程序。 I have built the WAR file as well. 我也建立了WAR文件。 Now I am in need of deploying this so it can be accessed online by anyone. 现在，我需要部署它，以便任何人都可以在线访问它。

I looked into lot of areas including normal web hosting. 我研究了很多领域，包括普通的网络托管。 However even though the services like DailyReazor are highly secured, they provide little for MySQL, around 250 MB for the package I selected. 但是，即使像DailyReazor这样的服务受到高度保护，它们也无法为MySQL提供任何服务，我选择的软件包只有250 MB。

Now I am looking into Amazon AWS. 现在，我正在研究Amazon AWS。 In AWS I am expecting to deploy my aplication and make it available online.The MySQL server should not contain limits like 250MB. 我希望在AWS中部署我的应用程序并使其在线可用.MySQL服务器不应包含250MB之类的限制。

But I have never ever used this service AWS before. 但是我以前从未使用过此服务AWS。 By reading various posts, I know that Elastic Beanstalk is the easiest way to go, but still not convinced about how to deploy it properly with database access and all. 通过阅读各种文章，我知道Elastic Beanstalk是最简单的方法，但仍然不相信如何通过数据库访问及所有操作正确地部署它。 And in the other hand, will they give me a web address like "www.example.com" or will they simply provide an IP address?? 另一方面，他们会给我一个“ www.example.com”这样的网址，还是只是提供一个IP地址？ I am also familiar with tomcat so I need to use it. 我也熟悉tomcat，所以我需要使用它。

We will not upload files (images etc) at the moment, so I believe we can manage with around 20$ per month? 我们目前不会上传文件（图片等），所以我相信我们每月可以管理大约20美元？

I really appreciate if someone can provide a clear guidance on deploying java web applications in Amazon, with the requirements I mentioned about MySQL, Global access and so on. 如果有人能够提供明确的指导，以我在上面提到的有关MySQL和全局访问等方面的要求，就可以在Amazon中部署Java Web应用程序提供明确的指导，我将非常感激。
