Client must be on the same host where virtual machine is executed Con: Significant overhead due to XML marshalling over the wire for each method call Pro: Relatively low invocation overhead In the following most cases, use the same programming language, web services use Internet standards such as HTTP and XML to communicate.1 In order to successfully use a web service, a number of things are required – primarily and XML. On the downside (and, one could say, typical of things related to XML), a lot of standards are involved before a web service can be implemented. Many of the standards invented around XML are used
