uddi 是否已不再使用,或者它的功能现在是否包含在 wcf 中?
现在还有人用uddi吗?或者它的功能现在包含在 WCF 中吗? Azure 是否改变了 UDDI 的实用性?您能给我一个使用 UDDI 的实际例子吗?
does anybody use uddi anymore? Or is it's functionality now encompasses by WCF? Does Azure change anything regarding to the usefulness of UDDI? Can you please give me a practical example when UDDI was used?

UDDI 已死,UDDI 背后的想法是在某种 Web 服务市场中发现 Web 服务及其功能。 IBM、微软和我认为 WebMethods 运营着公共 UDDI 服务器,但这些服务器在几年前就被关闭了,可能是由于缺乏兴趣。
实际上,您似乎可以将 Web 服务的 WSDL 描述放在托管 Web 服务的同一台服务器上。此外,许多框架将使用约定优于配置的原则,从代码和现有的 xsd 文件中为您生成 WSDL,有关示例,请参阅 Spring Web 服务。
UDDI is dead, the idea behind UDDI was to discover web services and their capabilities in some sort of web services marketplace. IBM, Microsoft, and I think WebMethods operated public UDDI servers, but those were shutdown a few years ago probably due to lack of interest.
In the real word it seems that you can just put your WSDL description of a web service on the same server that is hosting the web service. Also many frameworks will generate the WSDL for you from your code and existing xsd files using the principle of convention over configuration, see spring web services for an example.
问:现在还有人用uddi吗?
a:是的,它被使用了,不管你信不信,人们仍然在为它开发。
问:WCF 现在包含它的功能吗?
答:不,一点也不。 WCF 确实实现了称为 WS-Discovery 的功能,它使用多播发现来查找特定接口的实现,但是通过它可以共享的其他信息很少。
问:Azure 是否改变了 UDDI 的实用性?
a:不确定 Web 托管平台与 UDDI 的有用性有什么关系。您仍然需要做广告、发现和使用服务。
问:您能给我一个使用 UDDI 时的实际例子吗?
答: 什么时候用的?大概从 2001 年开始。它是如何使用的?
1) 动态 Web 服务客户端,在运行时查找服务绑定信息。
2)用户搜索服务提供商(促进代码重用)
3)运行时治理,参见Jboss Overlord
q: does anybody use uddi anymore?
a: Yes it is used and believe it or not, people still develop for it.
q: is it's functionality now encompasses by WCF?
a: No, not at all. WCF does implement something called WS-Discovery, which uses multicast discovery to find implementations of a specific interface, however little other information is sharable through that.
q: Does Azure change anything regarding to the usefulness of UDDI?
a: Not sure what a web hosting platform has to do with the usefulness of UDDI. You still need to advertise, discover and consume services.
q: Can you please give me a practical example when UDDI was used?
a: When it was used? probably since 2001. How it was used?
1) Dynamic web service clients that look up service binding information at runtime.
2) Users searching for providers of a service (promote code reuse)
3) Runtime governance, see Jboss Overlord
