There would be advantages to using message queuing for communicating between your services as it provides for async and fault-tolerant communication between them. 使用消息队列在服务之间进行通信将具有优势，因为它提供了服务之间的异步和容错通信。 Queued communication scales out well and enables parallel execution of activities very easily. 排队通信可以很好地扩展，并可以非常轻松地并行执行活动。
In terms of technology, you could use NServiceBus and the Particular Service Platform (full disclosure - I am the original creator of NServiceBus) or, if you're looking for something free then MassTransit could be a good choice. 在技术方面，您可以使用NServiceBus和特殊服务平台（完整披露-我是NServiceBus的原始创建者），或者，如果您正在寻找免费的东西，那么MassTransit可能是一个不错的选择。
If you're looking for a comparison between the two, see this SO question: 如果要在两者之间进行比较，请参见以下SO问题：
