This paper presents an Automated Telemedicine and diagnosis system (ATDS), is an expert system that is used for diagnosing many ailments such as malaria and others. and prescription of drugs. ATDS is made up of knowledge database. The end user makes use of it to determine if they are suffering from one ailment or the by entering the ailment symptoms. Once the system receives the information from the user, an instant drug prescription and diagnosis is made. ATDS is user-friendly. However, ATDS was not developed to replace the real doctors but to assist patient waiting for human doctors that are few and to make the diagnosing and prescribing of drugs faster and more accurate. ATDS is implemented in PHP (Hypertext Preprocessor). Hospitals and other medical clinics should be readily accessible by everyone when needed as one of the many limitations of health care establishment is distance. ATDS when compared with old systems like MYCIN is more efficient in the different aspects. It solved the problem of incomplete base. ATDS proves efficiency more than another medical expert system by giving instant and correct ailment diagnosis and drug prescription.

Recently, web services have presented a new and evolving model for constructing the distributed system. The meteoric growth of the Web over the last few years proves the efficacy of using simple protocols over the Internet as the basis for a large number of web services and applications. Web service is a modern technology of web, which can be defined as software applications with a programmatic interface based on Internet protocol. Web services became common in the applications of the web by the help of Universal, Description, Discovery and Integration; Web Service Description Language and Simple Object Access Protocol. The architecture of web services refers to a collection of conceptual components in which common sets of standard can be defined among interoperating components. Nevertheless, the existing Web service's architecture is not impervious to some challenges, such as security problems, and the quality of services. Against this backdrop, the present study will provide an overview of these issues. Therefore, it aims to propose web services architecture model to support distributed system in terms of application and issues.
