The widespread use of Service Oriented Architectures (SOA) is beginning to create problems derived from the governance of said structures. To date there is not a single effective solution to solve all existing challenges to govern this type of infrastructure. This paper describes the problems encountered when designing a SOA governance solution in a real e-Government scenario. More specifically, we focus on problems related to specification and automated analysis of government policies. We propose a novel SOA governance specification model as a solution to these problems. We have named this model WS-Governance. in order to ease its adoption by SOA practitioners it: i) shares WS-Policy guidelines and is compatible with it, ii) has XML serialization as well as a plain-text one and iii) has a CSP based semantics that provides a precise description as well as facilitating the automation of some editing and WS-Governance related activities such as consistency checking.

Sofware distribution models are moving to SaaS paradigms where customers no longer need to buy a perpetual license. In this con text, SaaS providers leverage the Service Level Agreement (SLA) concept to delimit the functionality and guarantees to which they commit to their customers. However, although formal specifications for the definition of SLAs have been proposed, providers usually have an ad-hoc approach with a low degree of automation. This approach confirms the fact that the SaaS industry has not incorporated the idea of an SLA model that can be implemented within the infrastructure as a decision mechanism. This instrumentation would be of special interest in RESTful microser vice architectures in providing an automated governance framework for the service catalog and regulating the behavior of each component in the context of the agreements reached with each client. This thesis project is divided in four stages: i) Establishing a sufficiently expressive specification for the description of RESTful microservices reg ulated by advanced SLAs; ii) Develop a catalog of SLA analysis and management operations to support the governance of micro-service ar chitectures; iii) Implement a SLAs management ecosystem to support the government of RESTful microservices; iv) Consolidation of the Governify platform to validate the proposal in industrial environments. ; Ministerio de Educación, Cultura y Deporte FPU15/02980 ; Ministerio de Economía y Competitividad BELI (TIN2015-70560-R) ; Junta de Andalucia COPAS (P12–TIC-1867))

Aiming to be as competitive as possible, organisations are always pursuing to improve their business processes applying corrective actions when needed. However, the actual analysis and decision mak ing for those actions is typically a challenging task relying on extensive human-in-the-loop expertise. Specifically, this improvement process usu ally involves: (i) to analyse evidences to understand the current behav ior; (ii) to decide the actual objectives (usually defined in Service Level Agreements -SLAs- based on intuition) and (iii) to establish the im provement plan. In this ongoing work, we aim to propose a data-driven and intuition-free methodology to define an SLA as a governance ele ment that specifies the service level objectives in an explicit way. Such a methodology considers process performance indicators that are analysed by means of inference, optimization, and simulation techniques. In order to motivate and exemplify our work we address a Healthcare scenario. ; European Union Horizon 2020 No. 645751 (RISE BPM) ; Ministerio de Economía y Competitividad BELI (TIN2015-70560-R) ; Junta de Andalucía P12-TIC-1867 ; National Research Foundation of Korea (No.NRF-2014K1A3A7A030737007)

In a changing and competitive business world, business processes are at the heart of modern organizations. In some cases, service level agreements (SLAs) are used to regulate how these business processes are provided. This is usually the case when the business process is outsourced, and some guarantees about how the outsourcing service is provided are required. Although some work has been done concerning the structure of SLAs for business processes, the definition of service level objectives (SLOs) remains a manual task performed by experts based on their previous knowledge and intuition. Therefore, an evidence-based approach that curtails humans involvement is required for the definition of realistic while challenging SLOs. This is the purpose of this paper, where performance-focused process mining, goal programming optimization techniques, and simulation techniques have been availed to implement an evidence-based framework for the definition of SLAs. Furthermore, the applicability of the proposed framework has been evaluated in a case study carried out in a hospital scenario. ; European Union Horizon 2020 No. 645751 (RISE BPM) ; Ministerio de Economía y Competitividad BELI (TIN2015-70560-R) ; Junta de Andalucía P12-TIC-1867

Quality of an open source software ecosystem (OSS ecosystem) is key for different ecosystem actors such as contributors or adopters. In fact, the consideration of several quality aspects(e.g., activeness, visibility, interrelatedness, etc.) as a whole may provide a measure of the healthiness of OSS ecosystems. The more health a OSS ecosystem is, the more and better contributors and adopters it will gather. Some research tools have been developed to gather specific quality information from open source community data sources. However, there exist no frameworks available that can be used to evaluate their quality as a whole in order to obtain the health of an OSS ecosystem. To assess the health of these ecosystems, we propose to adopt robust principles and methods from the Service Oriented Computing field. ; European Union EC-FP7 project RISCOSS (agr. 318249) ; Junta de Andalucía P12--TIC--1867 ; Junta de Andalucía TIC-5906 ; Ministerio de Economía y Competitividad TIN2012-32273 ; Ministerio de Ciencia e Innovación TIN2013-44641-P ; Ministerio de Economía y Competitividad IPT-2013-0890-3 ; Ministerio de Economía y Competitividad TIN2014-53986-REDT
