网格计算的商业用途？
我不断从同事那里听到有关网格计算的信息，据我所知，网格计算是高度分布式的东西，与 SETI@Home 类似。
有人在开发此类商业用途的系统吗？ 我的兴趣是弄清楚在这个领域开始软件开发是否有商业原因。
I keep hearing from associates about grid computing which, from what I can gather, is highly distributed stuff along the lines of SETI@Home.
Is anyone working on these sort of systems for business use? My interest is in figuring out if there's a commercial reason for starting software development in this field.

列举几个。
To list a few.
实际上，只有当您需要完成大量工作（例如折叠蛋白质）时才需要网格计算，否则一个简单的服务器场可能就足够了。
Grid computing is really only needed if you have a lot of WORK that needs to be done, like folding proteins, otherwise a simple server farm will likely be plenty.
显然，Google 是网格计算的主要用户； 他们所有的搜索服务以及许多其他服务都依赖于它。
BigTable 等引擎基于使用大量节点进行存储和计算。 这些在商业上非常有用，因为它们是少量大型服务器的良好替代品，提供更好的冗余和具有成本效益的扩展。
缺点是该软件非常难以编写，但谷歌似乎可以很好地管理这一点:)
所以任何需要大存储和/或大量计算的东西。
Obviously Google are major users of Grid Computing; all their search service relies on it, and many others.
Engines such as BigTable are based on using lots of nodes for storage and computation. These are commercially very useful because they're a good alternative to a small number of big servers, providing better redundancy and cost effective scaling.
The downside is that the software is fiendishly difficult to write, but Google seem to manage that one ok :)
So anything which requires big storage and/or lots of computation.
我曾经为这些人工作。 网格计算无处不在。 任何制造计算机芯片的人都会在切割物理芯片之前使用它们来测试设计。 金融网站使用网格来计算您是否有资格获得该贷款。 如今，它们开始在很多地方取代大铁，因为从长远来看，它们的维护成本往往更低。
I used to work for these guys. Grid computing is used all over. Anyone who makes computer chips uses them to test designs before getting physical silicon cut. Financial websites use grids to calculate if you qualify for that loan. These days they are starting to replace big iron in a lot of places, as they tend to be cheaper to maintain over the long term.
