Node.js云端的TCP套接字服务器[Heroku / AppFog] [英] Node.js TCP Socket Server on the Cloud [Heroku/AppFog]
问题描述
可以在 Cloud ，更具体地在 Heroku 或 AppFog 上运行Node.js TCP Socket导向的应用程序。
Is is possible to run a Node.js TCP Socket oriented application on the Cloud, more specifically on Heroku or AppFog.
它不是一个Web应用程序，而是一个用于访问客户端程序的服务器。基本思想是使用 Cloud - 扩展和一个易于使用的平台的功能。
It's not going to be a web application, but a server for access with a client program. The basic idea is to use the capabilities of the Cloud - scaling and an easy to use platform.
我知道这样的应用程序可以轻松地运行在IaaS上像Amazon AWS ，但我真的想利用 Heroku 或 的PaaS功能。
I know that such application could easily run on IaaS like Amazon AWS, but I would really like to take advantage of the PaaS features of Heroku or AppFog.
推荐答案
我相当肯定，没有回答手头的问题：是可能运行一个Node.js TCP Socket导向的应用程序。所有PaaS公司（包括Nodejitsu）都支持HTTP [S] - 仅用于传入连接的反向代理。
I am reasonably sure that doesn't answer the question at hand: "Is is possible to run a Node.js TCP Socket oriented application". All PaaS companies (including Nodejitsu) support HTTP[S]-only reverse proxies for incoming connections.
通常，使用node.js +任何PaaS以使用WebSockets，但
Generally with node.js + any PaaS with a socket oriented connection you want to use WebSockets, but:
-
Heroku不支持WebSockets，只保留打开连接55秒 https://devcenter.heroku.com/articles/http-routing#timeouts ）
AppFog不支持WebSockets，但我不确定如何处理长时间的HTTP连接。
AppFog does not support WebSockets, but I'm not sure how they handle long-held HTTP connections.
Nodejitsu支持WebSockets，并将保持您的连接打开，直到关闭或重置。我们的node.js驱动反向代理使我们非常便宜。
Nodejitsu supports WebSockets and will hold your connections open until closed or reset. Our node.js powered reverse-proxies make this very cheap for us.
我们计划支持前面TCP负载平衡与未来的自定义端口。敬请期待！
We have plans to support front-facing TCP load-balancing with custom ports in the future. Stay tuned!
