是否存在按需 Mac OS X 云服务，可与亚马逊的 EC2 按需实例相媲美? [英] Do on-demand Mac OS X cloud services exist, comparable to Amazon's EC2 on-demand instances?
问题描述
亚马逊的 EC2 服务提供了多种 Linux 和 Windows 操作系统选择，但我还没有找到为远程 Mac OS X 虚拟机提供类似按小时租用"服务的服务.有这样的服务吗?(iCloud 看起来只是一个数据存储服务，而不是一个允许远程登录等的服务)
Amazon's EC2 service offers a variety of Linux and Windows OS choices, but I haven't found a service offering a similar "rent by the hour" service for a remote Mac OS X virtual machine. Does such a service exist? (iCloud looks to be just a data storage service, rather than a service allowing remote login, etc.)
这样的虚拟机服务对于在可重现的中立"位置测试软件非常有用.
Such a virtual machine service would be very useful for testing software in a reproducible, "neutral" location.
更新 1:为了明确起见，我指的是类似于 EC2 的按需实例或点实例的服务，其中机器(或虚拟机)按小时租用，而不是涉及每月一次的典型网络托管服务订阅.正如@Erik 所指出的，这条路线有几个不错的选择.由于我使用每小时"或每小时费率"等术语搜索 OS X 托管的查询结果很少(基本上，只是每小时维修的人工费)，我倾向于相信这对某些人来说不存在原因.如果是这样，这样的公司为这些查询做广告似乎是合理的.
Update 1: Just to be clear, I'm referring to services similar to EC2's on-demand or spot instances, where the machine (or virtual machine) is rented per hour, rather than typical web hosting services that involve a monthly subscription. As @Erik has pointed out, there are several good options for that route. As my searches for queries for OS X hosting with terms like "per hour" or "hourly rates" are turning up very little (basically, just labor fees for hourly repairs), I am inclined to believe that this doesn't exist for some reason. If it did, it seems reasonable that such a firm would advertise for precisely these queries.
更新 2:我发现这个问题随着时间的推移越来越多.如果有人遇到情况发生变化，即有此类服务的提供者，请发帖，我将接受该答案.
Update 2: I see that this question is getting a lot of views over time. If someone encounters a change in the situation, i.e. that there is a provider of such services, please post and I will accept that answer instead.
推荐答案
我今晚刚遇到这个.不能说它们是否合法，营业多长时间，以及它们是否会持续很长时间，但似乎很有趣.我可能会尝试一下，如果我这样做，我会发布更新.
I just came across this tonight. Can't say if they are legit, how long in business, and whether they'll be around long, but seems interesting. I may give them a try, and will post update if I do.
根据网站，他们说他们提供按时付费和每周/每月计划，此外还有免费试用.
Per the website, they say they offer hourly pay-as-you-go and weekly/monthly plans, plus there's a free trial.
根据@Iterator，发布我对这项服务的发现的更新，从我的评论中移出:
Per @Iterator, posting update on my findings for this service, moving out from my comments:
我做了试验/评估.审判可能会误导审判的运作方式.您可能需要注册才能查看价格，但到目前为止，根据试用软件下载，试用似乎没有时间限制.只是功能受限.您注册以获得自己的帐户，但实际上您使用的是通用的试用登录帐户来进行试用，而不是您自己的帐户.当您实际支付服务费用时，将使用您自己的帐户.试用版限制了您可以执行、安装、保存等操作，但足以让您了解工作原理.因此，注册评估而不支付任何费用并没有什么坏处.
I did the trial/evaluation. The trial can be misleading on how the trial works. You may need to signup to see prices but the trial so far, per the trial software download, doesn't appear to be time limited. It's just feature restricted. You signup to get your own account, but you actually use a generic trial login account to do the trial, not your own account. Your own account is used when you actually pay for the service. The trial limits what you can do, install, save, etc. but good enough to give you an idea of how things work. So it doesn't hurt to signup to evaluate and not pay anything.
通过将文件保存到 DropBox(预安装，您只需要登录/配置)等来提供数据的持久性.没有 AMI、EBS 或某些 VM 映像的概念.他们的服务实际上就像一个共享网站托管解决方案，用户分时共享一台 Mac 机器(比如分时共享 Unix/Linux 服务器)，我认为他们限制或定期清除你放在机器上的内容，或者他们可能不备份您的文件，因此使用 DropBox 进行备份.如果需要，应与他们联系以澄清这一点.
Persistence of data is offered via saving files to DropBox (pre-installed, you just need login/configure), etc. There is no concept of AMIs, EBS, or some VM image. Their service is actually like a shared website hosting solution, where users timeshare a Mac machine (like timesharing a Unix/Linux server), and I think they limit or periodically purge what you put on the machine, or perhaps rather they don't backup your files, hence use of DropBox to do the backup. One should contact them to clarify this if desired.
他们有多种定价选项，正如您提到的全天通行证、20 美元的月度计划，以及 1 美元/小时的即付即用计划.根据我的使用情况，我可能会随用随付.即用即付基于预付积分(1 个积分 = 1 小时，按 30 个积分增量计费).一个警告是，您需要至少每 60 天定期使用该计划一次，以进行即付即用计划，否则您将失去未使用的积分.所以这就像每 60 天至少花费 1 个积分/1 小时一样.
They have various pricing options, as you mention the all day pass, monthly plans at $20, and their is a pay as you go plan at $1/hr. I'd probably go with pay as you go based on my usage. The pay as you go is based on prepaid credits (1 credit = 1 hour, billed at 30 credit increments). One caveat is that you need to periodically use the plan at least once every 60 days for the pay as you go plan or else you lose unused credits. So that's like minimum of spending 1 credit /1 hour every 60 days.
现在的最后一条评论，根据我的评估，您需要高带宽才能有效地使用该服务.它可以在 1.5 Mbps DSL 上使用，但响应速度有点慢.您可能希望从具有 Gbps 带宽的公司网络中使用它以实现最佳使用.或者至少是更高速的电缆/DSL 宽带连接.在我的上次测试中，在低带宽配置文件上~3Mbps 似乎足够了(它们有多个带宽连接配置文件，低、中、高，针对某些带宽范围进行了优化).我没有测试更高的.您的里程可能会有所不同.
One last comment for now, from my evaluation, you'll need high bandwidth to use the service effectively. It's usable over 1.5 Mbps DSL but kind of slow in response. You'd want to use it from a corporate network with Gbps bandwidth for optimal use. Or at least a higher speed cable/DSL broadband connection. On my last test ~3Mbps seemed sufficient on the low bandwidth profile (they have multiple bandwidth connection profiles, low, medium, high, optimized for some bandwidth ranges). I didn't test on the higher ones. Your mileage may vary.
