云计算和我公司的数据
我正在为我的公司寻找云计算。 我似乎无法摆脱的一个问题是： 如果云计算公司倒闭，我的数据以及使用这些数据的能力会怎样？
I am looking into Cloud Computing for my company. The one question that I can't seem to get out of my head is; What happens to my data and the ability to use it if the Cloud computing company goes out of business?

你并不孤单。 有很多人问同样的问题。 一些建议可确保您不会被冷落。
1) 仔细检查服务条款。 即使像亚马逊这样的一些较大的参与者也保留在不超过 30 天通知的情况下终止服务的权利。 如果您的整个网络基础设施都位于特定的云上，那么 30 天对于构建新的数据中心或迁移到其他提供商来说并不是很长的时间。 这引出了我的第二点……
2) 提供商之间的可移植性很重要。 如果被迫，专有云解决方案（Microsoft Azure、Google NetApps 以及较小程度上的 Amazon AWS）很难轻松过渡到其他提供商。 即将出现的一个有希望的选择是VMWare，它采用提供云软件并让合作伙伴托管它的方法。 理论上，这将为您提供提供程序之间的大量可移植性，甚至可能让您同时使用多个提供程序，以便进行故障转移。 此外，由于它们可能使用标准 VMDK 映像，因此如果您有 ESX 服务器，则在绝对必要时始终可以将虚拟机拉回到本地。
3）备份。 希望云提供商提供一些创建备份的方法，但建议也有离线版本。 较新的混合云架构对此很有吸引力，其中只有部分基础设施位于云上。 也就是说，您可以从云端进行本地备份。
这是一篇好文章，其中作者预测云市场的崩溃和 GoGrid.com 的反驳。 读起来非常有趣，因为你了解了问题的两面。

You aren't alone. There are a lot of people asking this same question. Some advice to make sure you aren't left out in the cold.
1) Examine the terms of service carefully. Even some of the bigger players like Amazon reserve the right to terminate service with no more than 30 days notice. If you had your whole network infrastructure on a particular cloud, 30 days isn't a long time to build a new data center or move to another provider. This brings us to my second point...
2) Portability between providers is important. Proprietary cloud solutions (Microsoft Azure, Google NetApps, and to a lesser extent Amazon AWS) make it hard to transition easily to another provider if forced to. A promising option on the horizon is VMWare who is taking the approach of providing the cloud software and letting partners host it. This would theoretically give you a lot of portability between providers and potentially even let you use multiple providers at once so you have a failover. Also, since they are likely to use standard VMDK images, if you have an ESX server you could always pull the Virtual machines back locally if absolutely necessary.
3) Backups. Hopefully the cloud provider offers some method for creating backups, but it is advisable to have an offline version as well. The newer hybrid-cloud architectures where only some of your infrastructure lives on the cloud is attractive for this. That is, you could backup locally from the cloud.
Here is a good article wherein the author predicts the collapse of the Cloud marketplace and a rebuttal by GoGrid.com. Very interesting read since you get both sides of the issue.

亚马逊和微软金融服务公司不会在一夜之间关闭商店。
Amazon and MSFT aren't going to shut down shop overnight.
显然，您应该选择一个您认为可靠且不太可能倒闭的提供商，但真正的答案是您应该准备好替代提供商，并制定如果主要提供商破产时如何切换的计划。 该计划的关键部分是：
外包服务器场实际上与任何其他外包功能没有什么不同。 您只需要确保您没有被单一供应商所束缚。
Obviously, you should pick a provider that you think is solid and unlikely to go out of business however the real answer is that you should have a replacement provider lined up and a plan for how you're going to switch if the main provider goes bust. The key parts of such a plan are:
An outsourced server farm is really no different to any other outsourced function. You just need to make sure you're not locked into a single supplier.
选择可靠的提供商并定期在云外备份您的数据。
Pick a solid provider and make regular backups of your data outside of the cloud.
我想说这取决于公司。 如果公司倒闭，我不认为你能够取回它。 即使您有这样做的合法权利，在公司倒闭后，也可能需要花费数月的时间通过法院命令和程序才能得到它。
公司破产后，我也不认为会有任何安全协议来保护它。 即使他们说会有，当一家公司破产时，所有的赌注都会落空。
还需要记住的是，即使是最“知名”的公司也可能会瞬间失败（安然公司或任何人）。 在财务报表（如果有）发布之前，您永远不会真正知道一家公司的经营状况如何。
I would say that it depends on the company. I wouldn't assume anything about you being able to retrieve it if the company goes out of business. Even if you have a legal right to do so, it will probably take months of going through court orders and procedures to get at it after the company fails.
After the company goes bankrupt, I also wouldn't assume there would be any security protocols in place to protect it. Even if they say there will be, when a company goes under all bets are off.
A think to also remember is that even the most "well known" companies can fail in a heartbeat (Enron anyone). You never really know how well a company is doing until the financial statements (if any) are released.
为什么不保留某种本地备份呢？ 此外，您可能想继续使用亚马逊等知名公司，因为它们可能不会倒闭。
编辑：
正如评论中所述，即使亚马逊停止提供云计算服务，他们也不太可能不给用户足够的时间将数据从服务器上移出。
Why don't you just keep a local backup of some sort? Also, you might want to stick with well known companies like Amazon where they probably wouldn't go out of business.
EDIT:
As stated in the comments, even if Amazon stopped offering their cloud computing service it's unlikely that they wouldn't give users ample time to move their data off of their servers.
