When can Web Services be more meaningful?

Currently, Web services is a fairly new technology, and not everyone knows how to make full use of them. With my experience (I once built a complete enterprise software product on the underlying architecture of Web services), I found that Web services has two main purposes: integrate multiple systems and provide functions as components for remote calls. This article describes the issues that need attention when using the latter method.
When you want to use Web service to submit a new function or service to a client that may be remotely called, you need to consider many factors. Whether this function is used internally or externally by customers or collaborators, designing an outline before starting a new Web service project in Visual Studio. NET will save you a lot of time. For example, when you require access to the exclusive database and/or when it is difficult to implement local deployment or when the cost is too high, it makes sense to provide a function as a Web service. Functions used to execute simple computing do not require access to exclusive data, and are not that complex in local deployment or maintenance.
When functional functions require a complex installation process or a complicated and expensive hardware configuration, using Web services may be your best choice. In this case, using functional functions as a Web service will solve a lot of troubles for your customers because they do not need to deploy them locally. If you often need to release a new version of a function, you should also consider using Web services. A Web service provides an easy way for all customers who use this function to release an upgraded version, instead of re-deploying the new version each time. It is not easy for the public to provide functions that require access to exclusive data through the Web service interface. In any case, the client needs to be able to obtain data, and the Web service is obviously a better method than to transmit flat file data. Finally, it is best to use functional functions that often change data as Web services. The increase in data update speed and data size makes the advantage of remote access to exclusive data more obvious.
Deployment is the most important factor when you decide whether to provide a function as a Web service. Web services makes software deployment easier. For example, if you are building an app that directs driving, you don't need to worry about installing the map software. Or if you have a function that requires frequent upgrades, you don't need to go back to the company every few months to ask them to help you deploy updates.
