Architektura orientovaná na služby, je přístupem k budování flexibilní a agilní architektury aplikací, která bude schopna v krátkém čase a s nižšími náklady reagovat na změny požadované ze strany businessu. Aby však organizace skutečně v SOA získala zdroj konkurenční výhody, je třeba zaměřit se kromě aplikací a architektury i na jejich správu a řízení IT se zohledněním specifik, které SOA do této oblasti přináší. Mezi hlavní podmínky efektivního provozu SOA patří optimální implementace procesů, organizační opatření a nástroje pro správu a monitoring architektury, aplikací a podpůrné infrastruktury. Předmětem této práce je poskytnutí celkového pohledu právě na roli procesů a nástrojů pro správu architektury orientované na služby a modelový příklad řízení SOA v telekomunikační firmě.

Nachdem in den letzten Jahren die TCO (Total Cost of Ownership) von IT-Systemen stärker in das Bewußtsein der Unternehmen rückten, wurden schnell Werkzeuge zur optimaleren Verwaltung von IT-Systemen angeboten. Unter Verwendung und Weiterentwicklung bereits bestehender Werkzeugen zum Netzwerkmanagement wurden integrierte Lösungen angeboten. Der Begriff 'Enterprise-IT-Management' war geboren. Wie immer bei solchen neuen Begriffen, die von Herstellern zugehöriger Werkzeuge stammen, wird auch beim Enterprise-IT-Management eine einheitliche Definition vermißt. Die Arbeit gibt eine Überblick über das Thema Enterprise-IT-Management und seiner Teildisziplinen. Dabei wird eine Definition der Teile angegeben, anhand derer Produkte hinsichtlich ihrer Fähigkeiten und besonders hinsichtlich ihrer Vollständigkeit verglichen werden können. Weiter Abschnitt wird am Beipiel der SBS GmbH & Co. OHG dargestellt, wie IT-Systeme heute verwaltet werden. Anschließend wird eine mögliche Integration aller dieser Arbeiten zu beschrieben, die das Management optimieren könnte. Dabei wird auch auf notwendige Umstrukturierungen der Tätigkeiten im Unternehmen eingegangen. Letztlich soll ein Überblick über derzeit am Markt verfügbare Werkzeuge gegeben und ein Vergleich hinsichtlich einiger Eigenschaften der Produkte durchgeführt werden, die an administrativen Erfordernissen des IT-Management orientiert sind.

Several surveys indicate that corporate leaders still consider the aligning of IT and business functions as a top management issue. The aim of this thesis is to illustrate how coordination emerges between IT and business departments and how formal structures intended to coordinate are influenced by human action. To deepen the understanding of this phenomenon we seek to analyze IT/business coordination from a perspective based on practice theory. A field study was conducted where observations and informal interviews were carried out at the IT department of a global company. The empirical analysis indicate that coordination problems between IT and business departments is in part affected by embedded factors such as different goals and perspectives on how IT is to be used in the organization or how to design IT related processes. Our findings suggest that social interaction plays an important role for coordination. It can enhance existing formal structures or create new structures, which improve the possibilities to coordinate between IT and business departments. Our findings also show how formal structures such as cross-functional roles can constitute conditions to initiate social interaction. The results can be used as indicators for how to enhance coordination between IT and business departments.

Most companies relying on an Information Technology (IT) system for their daily operations heavily invest in its maintenance. Tools that monitor network traffic, record anomalies and keep track of the changes that occur in the system are usually used. Root cause analysis and change impact analysis are two main activities involved in the management of IT systems. Currently, there exists no universal model to guide analysts while performing these activities. Although the Information Technology Infrastructure Library (ITIL) provides a guide to the or- ganization and structure of the tools and processes used to manage IT systems, it does not provide any models that can be used to implement the required features. This thesis focuses on providing simple and effective models and processes for root cause analysis and change impact analysis through mining useful artifacts stored in a Confguration Management Database (CMDB). The CMDB contains information about the different components in a system, called Confguration Items (CIs), as well as the relationships between them. Change reports and incident reports are also stored in a CMDB. The result of our work is the Decision support for Root cause Analysis and Change impact Analysis (DRACA) framework which suggests possible root cause(s) of a problem, as well as possible CIs involved in a change set based on di erent proposed models. The contributions of this thesis are as follows: - An exploration of data repositories (CMDBs) that have not been previously attempted in the mining software repositories research community. - A causality model providing decision support for root cause analysis based on this mined data. - A process for mining historical change information to suggest CIs for future change sets based on a ranking model. Support and con dence measures are used to make the suggestions. - Empirical results from applying the proposed change impact analysis process to industrial data. Our results show that the change sets in the CMDB were highly predictive, and that with a confidence threshold of 80% and a half life of 12 months, an overall recall of 69.8% and a precision of 88.5% were achieved. - An overview of lessons learned from using a CMDB, and the observations we made while working with the CMDB.

This thesis focuses on the identification of experience required for solving IT (Information Technology) problems in small to medium sized enterprises. It is aimed to utilize information retrieval and data mining techniques to automatically extract information from publicly available experience data on the internet to automatically generate a knowledgebase for dynamic IT management support. In this thesis, similarity distance measures as Jaccard Index, Cosine Similarity Measure and clustering algorithms as K-Means, EM, DBScan, CES, CES+ are employed on three different datasets to evaluate their performances. CES+ algorithm gives the highest performance results in these evaluations. Moreover, Multi Objective Genetic Algorithm (MOGA) is used and is evaluated on three different data sets to aid the usage of CES+ in real life senarios by automating the selection of necessary parameters. Results show that MOGA support is not only automating the CES+, it also provides higher performance results.
