Recently, I am looking up some information about virtualization. I found it's so hot, while i don't think it worth it.
Virtualization is done!
Let's say that virtualization is feasible now. We have to consider these things.
First, it just transfer the hardware cost to the service provider, while we have to pay it eventually.
Second, what's the use of it? For efficience? Easy to manager the datas? I don't think so, if our network is fast, all our data can be on other servers, but our netword is not so wonderful. We have to tolerate the slow delivering process.
Third, it's not so easy to provide the software service for every client, because we have to pay a lot of money for the copyright. Maybe we can use the opensource software, but don't think so, if there are no profit, few body will make software.
