在云计算平台上开发应用会是未来的一个方向。将传统应用移植到云计算平台是一个很好的创业机会。
现在肯定是Amazon的云计算平台比较流行，原因是现在有很多的Legacy应用，将Infrastructure直接虚拟化可以很好的过度这些应用。但是Google的虚拟化平台所在的层次更高，或许在不远的将来会流行起来。当所有的应用到移植的Web上面，一些流行的框架都可以在Google App Engine上面运行的时候。
虚拟化平台的设计一定要将存储做成一个。
Hypervisor对于虚拟化来说不是必需的，看Google搭建的云计算环境就可以知道。Google重新设计的软件不需要Hypervisor的支持就可以完全使用硬件能力，加入一层Hypervisor会增加管理的复杂性。
压缩不一定是必需的，考虑一下现在的网卡速度是10Gbps，CPU计算资源反而成了瓶颈。

Servers on the Back End of Warhammer Online
Running the vast server farms underlying the Warhammer Online world cost-effectively requires using each server's resources efficiently. The Mythic technical team relies on the blade server architectures and application design to maximize server resource usage.
"We use blade architecture heavily for Warhammer Online," Mann noted. "Almost every server that we deploy is a blade system. We don't use virtualization; our software is somewhat virtualized itself. We've always had the technology to run our game world across several pieces of hardware. It's application-layer clustering at a process level. Virtualization wouldn't gain us much because we already run very close to peak CPU usage on these systems."
"We're watching developments in the virtualization area with interest," Shaw said, "as we plan for achieving maximum server efficiency with minimal power use in the future." Currently, power budgeting is handled automatically by the Dell powering options within the blade server cabinets. Mythic doesn't attempt to control any of the power usage at the application level.
