使用托管服务

多年以前我使用过PythonAnywhere，但是后来我使用nodejs了，我也需要类似的服务。heroku似乎可以接棒？免费？黑盒？对于业余玩家来说真的不需要太多的算力，网络，存储。

network

data store

mongodb as a service

redis as a service

mysql as a service

rocketmq as a service

web服务托管

静态资源托管 ‘

你不需要真正的拥有，你只需要一个网络访问权限。 你自己管理域名就好了

heroku是一个不错的选择

很惊奇heroku是在2007年就出来的一款产品。至少从思路上来说，这家公司是有很大前瞻性的。

add-ons的概念，我的理解就是一个插件的概念。你所需要的服务都可以通过插件的方式得到满足。

服务类别如下：例如数据存储，监控，日志等等。

The Twelve Factors

I. Codebase One codebase tracked in revision control, many deploys II. Dependencies Explicitly declare and isolate dependencies III. Config Store config in the environment IV. Backing services Treat backing services as attached resources V. Build, release, run Strictly separate build and run stages VI. Processes Execute the app as one or more stateless processes VII. Port binding Export services via port binding VIII. Concurrency Scale out via the process model IX. Disposability Maximize robustness with fast startup and graceful shutdown X. Dev/prod parity Keep development, staging, and production as similar as possible XI. Logs Treat logs as event streams XII. Admin processes Run admin/management tasks as one-off processes
