In market competition companies need a new generation of information services, which render a greater functionality and grant access to different services on demand. Companies intend to implement a flexible architecture, which allows integration of applications across one platform efficiently. Service-oriented architecture is a beneficial tool for managing systems within an enterprise, using which the performance of business processes can be leveraged, and different costs can be minimized. The aim of this bachelor statement «Analysis of Efficiency of Service-oriented Architecture in IT Company» is to prove the efficiency of SOA implementation in an enterprise. To target the aim the following tasks are proposed: description of SOA concepts, analysis of relevant foreign and Russian publications, modeling of one business process that requires system integration, measurement of some figures in the course of a system integration case, forming a list of recommendations for successful SOA implementation. To complete the tasks such methods as qualitative, comparative, and descriptive analysis, process modeling, and using integration cases are implied. This work provides evidence of relevance of the subject based on literature review, demonstrates system interaction during one business process, and presents the process as an EPC diagram and a block diagram. A practical example explains how web-services work and concludes that implementation of web-services and a distributed architecture is beneficial for business processes. Besides, an integration case, namely invoking a web-service method for checking data in adjacent systems, is described. This case is compared to a similar case of accessing data in a centralized architecture. Both cases are evaluated in terms of performance. In conclusion, implications and findings are rendered, the main hypothesis is proved, and the list of recommendations for successful SOA implementation is provided.
