我们的公司正在考虑托管自己的服务器，以EC2动，我想知道，这是一个好主意。

Our company is considering moving from hosting our own servers to EC2 and I was wondering if this was a good idea.

我已经看到了很多东西可以左右云计算（特别EC2）做X，还是可以做Y，但我真正的问题是，为什么你不希望使用它？

I have seen a lot of stuff about can cloud computing (and specifically EC2) do x, or can it do y, but my real question is why would you NOT want to use it?

如果你是企业设立，是什么原因，你会选择去通过管理自己的服务器的麻烦（成本之外）？

If you were setting up a business, what are the reasons (outside of cost) that you would choose to go through the trouble of managing your own servers?

我知道有很多的成本计算，你可以把有关的带宽，磁盘使用情况等，但也有，当然，对于维护自己的服务器的其他费用。为了这个讨论，我愿意考虑成本基本相当。

I know there are a lot of cost calculations you can put in regarding bandwidth, disk usage etc, but there are of course, other costs regarding maintenance of your own server. For the sake of this discussion I am willing to consider the costs roughly equal.

我似乎记得乔尔Spolsky的写了这一点模糊在同一时间，但我无法找到它。

I seem to remember that Joel Spolsky wrote a little blur on this at one time, but I was unable to find it.

任何人有什么原因呢？

谢谢！

推荐答案

我能想到的几个原因，为什么不使用EC2（和我说的EC2，不是一般的电网补偿）：

I can think of several reasons why not use EC2 (and I am talking about EC2, not grid comp in general):

可靠性：亚马逊不保证为向可用性/下降时间/ EC2安全 安全：亚马逊不作出任何保证向谁就会泄露你的数据 持久性：确保你的数据（包括，努力建立系统）的持久性是复杂的在EC2 管理：很少有集成的管理工具，用于部署在EC2云 网络：虚拟网络，允许EC2实例来进行通信具有一定相当痛苦的限制（延迟，无组播，任意拓扑位置） Reliability: Amazon makes no guarantee as to the availability / down time / safety of EC2 Security: Amazon does not makes any guarantee as to whom it will disclose your data Persistence: ensuring persistence of your data (that includes, effort to set up the system) is complicated over EC2 Management: there are very few integrated management tools for a cloud deployed on EC2 Network: the virtual network that allows EC2 instances to communicates has some quite painful limitations (latency, no multicast, arbitrary topological location)

和完成的：

的 成本的：从长远来看，如果你不使用EC2吸收话务高峰，这将是远远超过投资于自己的服务器更加昂贵（像超微成本只是一对夫妇的一百块钱......）小气鬼服务器

在另一边，我仍然认为EC2是一个伟大的方式来吸收非敏感的交通高峰期，如果你的架构允许它。

On the other side, I still think EC2 is a great way to soak up non-sensitive peak traffic, if your architecture allows it.
