首先，来介绍下啥是 TSF Serverless ，TSF-S 全称 Serverless 微服务平台（Tencent Service Framework Serverless，TSF Serverless）是可承载核心生产应用的一站式 Serverless 开发平台。
或者可以理解为原 TSF（微服务平台，偏 Spring Cloud 、Service Mesh ） Serverless 化，最关键的是，目前Serverless部署组会支持node.8.9,并且有望支持几乎全栈开发语言。
哈哈，讲了这么多，我们来看一个栗子吧：
http://socket1-1251746107.gz.apigw.tencentcs.com/
这是一个很简单的socket.io搭建的demo,可以实现实时同步聊天的基础socket能力,主要依赖express+socket，废话有点多了，下面我们来看如何上手吧：
TSF-S现在处于内测阶段，感兴趣的童鞋可以去这里申请内测资格：
https://cloud.tencent.com/apply/p/om62iz2gqx
首先，进行第一步，大家都不陌生的初始化，随便建一个目录就可以开始了！
npm init
完成后，我们来在本地打包依赖（注意，目前TSF-S不支持在线打包哦，我们需要将所有环境都配置好）
npm install express –save
npm install –save socket.io
git clone https://github.com/socketio/chat-example.git # socketio demo
完成后大致是这样的：
其实，我们现在在本地跑 node index.js 也是可以运行的。
重点来了，如果我们将包整个打到TSF-S其实是没法知道我们到底在跑什么命令或者配置的，所以我们需要增加一个 start.sh文件，它用的是shell脚本，所以你懂得.jpg。
具体启动命令可以参考这个：
#! /bin/bash node index.js
当然，也可以搞成这样
#!/bin/sh
already_run=`ps -ef|grep "node index.js"|grep -v grep|wc -l`
if [ ${already_run} -ne 0 ];then
echo "node app already Running!!!! Stop it first"
exit -1
fi
nohup node index.js &
然后的然后，我们将文件打包为ZIP，就可以进行下一步的上传啦。
如果想要了解更多start.sh的情况，可以点我
比较懒的同学可以用我打包好的demo例子：
我们可以直接点进下面的链接：
https://console.cloud.tencent.com/tsf/app?rid=1
然后选择 “新建应用”
没错，就是红框那个，大家可以放心大胆的用，现在内测似乎是免费的。
创建完成后，根据提示上传我们的程序包，这里就是我们刚刚在本地打包好的项目啦~哈哈哈
然后我们选到部署组并新建：
大功告成，我们只需静待应用部署完成即可。
当然，我们可以在 “访问管理” 配置APIGW的访问地址，就像文章最前面写的地址一样
其实，个人觉得SCF相较于TSF-S，函数封装的方式会劝退很大一部分开发者，涉及的业务改造面太广。反而类似TSF-S这种配合微服务的事务管理，全链管理等轻量级Serverless微服务应用可能会更受开发者喜欢。

The other day, while I was at work, my sister stole my iphone and tested to see if it can survive a forty foot drop, just so she can be a youtube sensation. My apple ipad is now broken and she has 83 views. I know this is entirely off topic but I had to share it with someone!
