The systems built under this paradigm, known as Service Based System (SBS), are composed of several services, which are usually third-party software run by external service providers. SBS rely on these service providers to ensure that their services comply with the agreed Quality of Service (QoS). In contrast to\r\nother systems, the dynamic behaviour of SBS requires up-to-date QoS information for its proper management in the different stages of its lifecycle, from their initial construction until their decommission.\r\nProviding such QoS information has resulted in different technological solutions built around a monitor. Nonetheless, several research challenges in the field remain still open, ranging from theoretical aspects of quality assurance to architectonical challenges in decentralized monitoring.\r\nBased on the current research challenges for service monitoring, the research gaps in which we aim to contribute are twofold:\r\n- To investigate on the definition and structure of the different quality factors of services, and provide a framework of common understanding for the definition of what to monitor.\r\n- To investigate on the different features required to support the activities of the whole SBS lifecycle (i.e. how to monitor), and develop a monitoring framework that accomplishes such features.\r\nAs a result of this thesis, we provide:\r\nWhat to monitor\r\n- A distribution of the quality models along the time dimension and the identification of their relationships.\r\n- An analysis of the size and definition coverage of the proposed quality models.\r\n- A quantified coverage of the different ISO\/IEC 25010 quality factors given by the proposals.\r\n- The identification of the most used quality factors, and provided the most consolidated definitions for them.\r\nHow to monitor\r\n- The elicitation of the requirements of the different activities in the SBS lifecycle.\r\n- The definition of the set of features that supports the elicited requirements.\r\n- A modular service-oriented monitoring framework, named SALMon, implementing the defined features. SALMon has been validated by including it in several frameworks supporting the different activities of the SBS lifecycle. Finally, we have conducted a performance evaluation of SALMon over real web services.<\/jats:p>\n                <jats:p>La Computaci\u00f3 Orientada a Serveis (SOC) ha esdevingut en els darrers anys un paradigma exit\u00f3s en el camp de l'Enginyeria del Software. Els sistemes constru\u00efts sota aquest paradigma, coneguts com Sistemes Basats en Serveis (SBS), estan composats de diversos serveis, que s\u00f3n, usualment, programari de tercers executats per prove\u00efdors de serveis externs. Els SBS depenen dels prove\u00efdors dels serveis per garantir que els serveis compleixen amb la Qualitat del Servei (QoS) acordada. En contrast amb altres sistemes, el comportament din\u00e0mic dels SBS requereix d'informaci\u00f3 actualitzada del QoS per a la correcta administraci\u00f3 de les diferents etapes del cicle de vida dels SBS: des de la seva construcci\u00f3 inicial fins a la seva clausura. Proveir d'aquesta informaci\u00f3 de QoS ha resultat en diferents solucions tecnol\u00f2giques constru\u00efdes al voltant d'un monitor. Malgrat aix\u00f2, diversos reptes de recerca en el camp encara romanen obertes, des d'aspectes te\u00f2rics de l'asseguran\u00e7a de qualitat, a reptes arquitect\u00f2nics en la monitoritzaci\u00f3 descentralitzada. Basat en els reptes de recerca actuals per a la monitoritzaci\u00f3 de serveis, els forats de recerca en els que pretenem contribuir s\u00f3n dobles: - Investigar en la definici\u00f3 i estructura dels diferents factors de qualitat dels serveis, i proveir un marc de treball d'entesa comuna per a la definici\u00f3 de qu\u00e8 monitoritzar. - Investigar en les diferents caracter\u00edstiques requerides per donar suport a les activitats de tot el cicle de vida dels SBS (i.e. com monitoritzar), i desenvolupar una plataforma de monitoritzaci\u00f3 que acompleixi aquestes caracter\u00edstiques. Com a resultats de la tesis, prove\u00efm: Qu\u00e8 monitoritzar - Una distribuci\u00f3 dels models de qualitat al llarg de la dimensi\u00f3 temporal i la identificaci\u00f3 de les seves interrelacions. - Un an\u00e0lisi de la mida i definici\u00f3 de la cobertura dels models de qualitat proposats. - Una cobertura quantificada dels diferents factors de qualitat ISO\/IEC 25010 donat en les diferents propostes. - La identificaci\u00f3 dels factors de qualitat m\u00e9s utilitzats, i la definici\u00f3 dels termes m\u00e9s consolidats. Com monitoritzar - L'elicitaci\u00f3 dels requeriments per a les diferents activitats en el cicle de vida dels SBS. - La definici\u00f3 del conjunt de caracter\u00edstiques que donen suport als requeriments elicitats. - Una platforma modular orientada a serveis, anomenat SALMon, que implementa les caracter\u00edstiques definides.
