寻找force.com与其他云服务的比较它的定价模型
最近我一直在关注force.com，它恰好是SalesForce.com 的云计划。然而，我无法画出它与亚马逊和亚马逊的比较。 Azure 平台。 Force.com 似乎主要针对企业，所以我不确定作为一个小商店，我是否应该走这条路。我的将是一个社交网络门户。 Force.com吸引我的是“chatter”平台。我正在努力寻找有关使用该平台的定价信息。大多数定价详细信息都以 $xyz/用户/月的格式编写。现在这对于企业来说可能会很顺利，但对于像我这样想要建立用户数量不可预测的社交网络的人来说则不然。我有一种感觉，我在某个地方错过了一些东西。此外，我没有看到太多关于该平台的评论。有人也可以解释一下吗？
Lately I've been looking at force.com which happens to be SalesForce.com's cloud initiative. However, what I am unable to draw is its comparison with Amazon & Azure platforms. Force.com seems to be targeting Enterprises primarily, so I am not sure if as a small shop, I should be going that way. Mine is going to be a social networking portal. What attracted me to force.com is the 'chatter' platform. I am struggling to find information w.r.t. pricing of using this platform. Most of the pricing details are written in the format $xyz/user/month. Now that may go well for an enterprise but not for someone like me who is going for a social networking with unpredictable number of user. I get a feeling that I am missing something somewhere. Further, I don't see many review about the platform. Can someone throw some light on that as well?

Force.com 绝对是一个 PaaS 产品，这使得 SFDC 不仅仅是一个 CRM SaaS 玩家。话虽如此，我认为他们不会很快（如果有的话）将 Chatter 作为独立应用程序提供。 Force.com 确实有自己的定价模式。这些都可以在他们的网站上轻松获得。
一如既往，这取决于您想要实现的目标。 Force.com 非常适合基于表单、以数据为中心的应用程序开发 - 如果您有兴趣了解 Force.com 的理想应用程序开发情况，请查看 Jason Ouelette 有关 Force.com 的书。我怀疑即使是最积极的 Force.com 支持者也不会认为 Force.com 是实现您目的的理想选择。 Zoho 和 Caspio 也提供数据驱动的 PaaS，但我再次认为这不适合您的应用程序。
如果我处于您的位置，我会尝试利用已经为社交网络目的开发的平台，例如 Ning 甚至 Google Groups 之类的平台。您能否通过现成的免费服务实现 90% 以上的最终用户功能？
这篇文章很旧，但也许除了 Ning 之外的一些示例可能会有所帮助：http://www.techcrunch.com/2007/07/24/9-ways-to-build-your-own-social-network/
原力。 com 开发者挑战表明您可以在 Force.com 上构建几乎任何东西，但仅仅因为您可以做某事并不意味着您应该这样做。
对于其他受访者 - 如果您不认真对待 PaaS（一般而言）和 Force.com（具体而言）作为自定义应用程序开发平台，那么您就落后了。 Force.com 是一个很棒的平台，但我认为它不太适合您的特定需求。
Force.com is absolutely a PaaS offering making SFDC more than a CRM SaaS player. That being said I do not see them offering Chatter as a stand-alone application anytime soon, if ever. Force.com does have it's own pricing model. This is all readily available on their web site.
As always, it depends on what you want to achieve. Force.com is ideal for forms based, data-centric application development - check out Jason Ouelette's book on Force.com if you're interested in learning ideal app dev situations for Force.com. I suspect even the most aggressive Force.com supporters would not think of Force.com as being ideal for your purposes. Zoho and Caspio offer data driven PaaS as well, but again I do not think this is ideal for your application.
If I were in your position I would try to leverage a platform already developed for social networking purposes like Ning or even something like Google Groups. Can you achieve 90%+ of the end user functionality you're looking for with free services readily available?
This article is old but perhaps some of these examples other than Ning might help: http://www.techcrunch.com/2007/07/24/9-ways-to-build-your-own-social-network/
The Force.com developer challenges have shown you can build just about anything on Force.com, but just because you can do something doesn't mean you should.
To the other respondents - if you're not taking PaaS, in general, and Force.com, specifically, seriously as Custom App Dev platforms then you're behind the curve. Force.com is a great platform but I do not think it is well suited for your particular needs.
Force.com 未能兑现关键的云承诺之一：可扩展性。这是一个资源非常有限的环境，如果您客户的业务模型与 Salesforce 的模型不相符，那么在其上开发 CRM 产品也可能是一种尝试。对于休闲社交网络平台来说，这绝对不是正确的解决方案。你签约后将被束缚，但收获微乎其微。
Force.com fails to deliver on one of the key cloud promises: scalability. It is a very resource-constrained environment, and developing even CRM products on it can be a trial if your customer's model of their business is not in line with Salesforce's. It is definitely not the right solution for a casual social-networking platform. You will be signing up to have your hands tied for very little gain.

提供一些开发人员对 Force 的看法。 com 平台。您绝对不想使用 Chatter 应用程序，因为它可供“组织”使用，但每个用户都需要您组织的许可证才能访问 Chatter。
有一个允许 100 个用户的免费版本，因此理论上您可以创建一个包含 100 个用户的网络，但之后您必须开始付费。
A couple of links for you:
force.com evening the score and force.com VS net
Give a bit of a developers view on the force.com platform. You absolutely don't want to use the chatter application as it is available to an "org" but each user will need a license on your org to gain access to chatter.
There is a free edition which allows 100 users, so you could theoretically create a network of 100 users, but after that you'd have to start paying.
SFDC 也是一个平台，类 Java 语言 (APEX) 的功能随着时间的推移而显着增长。
至于定价，有很多不同的选择。有轻度用户和标准用户，以及基于带宽的定价。您还可以与 Salesforce 协商定价，但据我所知，没有人基于 Force.com 构建大众市场应用程序，主要是因为这些问题。
SFDC is also a platform, and the capabilities of the Java-like language (APEX) have grown significantly over time.
As for pricing, there are a lot of different options. There are light users and standard users, as well as pricing based on bandwidth. You can also negotiate with Salesforce over the pricing, but AFAIK there are not people building mass market applications based off of Force.com, largely because of these issues.
