AWS Lamdba能讲到外部Internet服务？ [英] Can AWS Lamdba Speak to external Internet Services?

问题描述

与地面通过AWS革命性的突破完全管理功能的编程支持;可以AWS拉姆达到外部Internet网络/系统外部通信说话。

这个想法/动机是，如果AWS Lamdba使用NodeJS SDK的服务PubNub，推 - 这将是很好卸载实时通信的处理方面

解决方案

简短的回答是肯定的。由于LAMBDA运行在一个节点沙箱中，没有什么阻止你捆绑起来像申请，并从内部用它你的函数。不过，也有一些限制需要考虑：

1. 有60秒执行硬上限，因此，如果您的要求要花很长时间的功能，可以超​​时

2. LAMBDA放置在网络功能有一些限制：

     

   入站网络连接是通过AWS LAMBDA，只有TCP / IP管理   插座的支持，和ptrace的（调试）系统调用   限制。

With the ground breaking revolutionary fully managed functional programming support by AWS; can AWS lambda speak to external internet / systems for external communication.

The idea / motive is if AWS Lamdba use the NodeJS SDK for services PubNub, Pusher - it would be nice to offload the handler aspect of the real time communication.

解决方案

The short answer is yes. Since Lambda runs in a Node sandbox, there's nothing stopping you from bundling up something like request and using it from within your function. However, there are a few limitations to consider:

1. There is a hard upper limit of 60 seconds for execution, so if your requests take too long your function could timeout

2. Lambda places some restrictions on network capabilities:

   Inbound network connections are managed by AWS Lambda, only TCP/IP sockets are supported, and ptrace (debugging) system calls are restricted.
