我当初还很天真地以为甚么东西放在 AWS 上都能够 scalable ……
结果被同事被视了……
"AWS won't have any more processing power then your servers. AWS is not something magical that allows multiple servers to pool cpu power together. You will still be limited by the Max cpu cores in their nodes."
之后我找到了这篇文章《The Limitations of Scaling with EC2》提到……
"The biggest limitations of Amazon’s EC2 at the moment as I have experienced, are the latencies between instances, latencies between instances and storage (local, and EBS), and a lack of powerful instances with more than 15GB of RAM and 4 virtual CPUs."

大家觉得 AWS 还有甚么 shortages?
又要如何 overcome ?

Take ec2 instance as normal server node.cluster both application server and db.

GordianZ MOD 那个4CPU/15GB的限制早没了，08年的文章已经没什么参考性了。

kayue OP 想问一下如果想程式能够跑在multiple instance ，需要做任何修改吗？

No code change need for a single instance. Cluster the instances for client.
