PaaS：如何构建？ [英] PaaS : How to build?

问题描述

• 用户（最终用户）可以创建自己的
  在线应用程序。
  

• 将与
  数据库和application / web
  服务器集成



• 并且用户也可以发布那个
  应用程序，并且只有该应用程序
  ...

研究，我才知道它属于PaaS（平台即服务）类别。

但我很困惑我该怎么做？
我想用Java / J2EE构建应用程序。

任何人都可以从哪里解释我应该从哪里开始？
或者哪个框架/技术更适合在Java中实现它？

等待您的回复....

解决方案

选择PaaS有几种选择 - 每个PaaS供应商都有其优缺点，因此您需要考虑一系列问题：

• 语言支持 - 您只需要Java还是其他语言/框架？


• 托管 - 您打算使用像亚马逊网络服务这样的云计算提供商？或者你使用自己的硬件？或者您想要多个选项？


• 数据库支持 - 您提到使用中央数据库。你打算自己安装/管理这个DB，还是使用托管数据库服务？你需要PaaS来支持你想要的特定DB吗？也许你需要多个数据库来提供可扩展性和客户端间的分离？

PaaS供应商有几个比较好的比较。这可能是一个很好的开始：寻找PaaS提供商的建议

I wanted to make a web application through which :

• user(end user) can create his own web application online.

• which will be integrated with the databases and application/web servers

• and user can also publish that application withing that application only...

Doing some research i come to know it goes under category of PaaS(Platform as a Service)

But i am confuse how can i do that ? I want to build that application using Java/J2EE.

Can any one explain me from where should i start ? Or which framework / technology is better to implement it in Java ?

Waiting for your helpful reply....

解决方案

There are several options as far as choosing a PaaS - each PaaS vendor has its pros and cons, so you need to consider a range of issues:

• Language support - Do you want just Java or maybe additional languages/frameworks?
• Hosting - Are you going to use a cloud computing provider like Amazon Web Services? Or are you using your own hardware? Or do you want multiple options?
• DB support - You mentioned using a central DB. Do you plan on installing/administering this DB yourself, or use a hosted DB service? Do you need the PaaS to support the particular DB you want? Perhaps you need multiple Databases to provide scalability and separation among clients?

There are several good comparisons of PaaS vendors out there. This might be a good place to start: Looking for PaaS providers recommendations
