把loading processes放到amazon cloud,让cloud自己处理。load完了再把数据copy回
公司自己的Database。
-俺没看出来为啥要java。

This is a reasonable process if your company doesn't have the computing
power and have relative little data and heavy computation in your need.
e.g. I know some dating site uses EC2 to match their millions of accounts,
and they rent a huge cluster on EC2 a few hours a day.
This is not necessarily java, but if framework like Hadoop makes sense
for the job, Java will be the best choice.

然后java team又胎死服中了?哈哈。
其实我们的问题是file来了不是马上process,而是schedual的job。所以每天上午系统
负担过重。

Depends on your usage and your revenue, it makes sense for some
companies but not for all. You can find the pricing information
yourself on Amazon.
EC2 is pretty much virtual linux boxes. You still need DBA and Developers.

: ?我以为很便宜。
: 其实我想是把整个公司系统都搞上去,然后把DBA, Developer都开了,俺觉得他搞的不
: 够大,这个只能让他自己没事做。
