Service Oriented Architecture (SOA) is an emerging architectural style becoming broadly adopted as it offers the ability to develop low-cost, flexible, and scalable distributed systems by composing ready-made services. This architectural style can be implemented using a wide range of SOA technologies such as AJAX, OSGI, REST, RPC, SOAP, SCA, and Web Services. However, the emergence of such service-based systems (SBSs) raises several challenges. Indeed, like any other complex software system, SBSs must evolve to fit new user requirements and new execution contexts. These changes to accommodate new user requirements and execution contexts degrade the design and quality of service (QoS) of SBSs and often result in the appearance of common bad practice solutions, called antipatterns--by opposition to patterns, which are good solutions to common recurring problems. In addition to the degradation of the design and QoS, antipatterns resulting from these changes hinder the maintenance and evolution of SBSs and make it hard for software engineers to maintain and evolve software. Moreover, the dynamic nature of an SOA environment involves that antipatterns are also dynamic, and thus their detection and correction must be performed at runtime. The long-term goal of this research program is to assess and improve the design and QoS of SBSs through the automatic detection and correction of SOA antipatterns. More precisely, this goal will be achieved by developing and applying a novel and innovative methodology supported by a framework to specify, detect, and correct automatically, at runtime, SOA antipatterns in large scale SBSs relying on different SOA technologies. The originality of this program lies in the dynamic nature of the SOA environment and its various underlying technologies. This methodology will deepen our understanding on antipatterns, design, and QoS in SBSs, and allow the development of tools intended for software engineers to assess and improve the design and QoS of SBSs handled by end-users, and ease their maintenance and evolution tasks.

面向服务的体系结构（SOA）是一种新兴的体系结构风格，由于它提供了通过组合现成的服务来开发低成本、灵活和可伸缩的分布式系统的能力，因此被广泛采用。这种体系结构风格可以使用各种SOA技术来实现，例如AJAX、OSGI、REST、RPC、SOAP、SCA和Web服务。然而，这种基于服务的系统（SBS）的出现提出了一些挑战。事实上，像任何其他复杂的软件系统一样，SBS必须发展以适应新的用户需求和新的执行环境。这些变化，以适应新的用户需求和执行上下文降低了设计和服务质量（QoS）的SBS，并经常导致常见的不良做法的解决方案，称为反模式的外观-通过反对模式，这是很好的解决方案，常见的复发性问题。除了设计和QoS的退化之外，由这些变化产生的反模式阻碍了SBS的维护和演化，并且使软件工程师难以维护和演化软件。此外，SOA环境的动态特性涉及到反模式也是动态的，因此它们的检测和纠正必须在运行时执行。 本研究计划的长期目标是通过自动检测和纠正SOA反模式来评估和改进SBS的设计和QoS。更确切地说，这一目标将通过开发和应用一种新颖的和创新的方法来实现，该方法由一个框架支持，在运行时自动指定、检测和纠正依赖于不同SOA技术的大规模SBS中的SOA反模式。该计划的独创性在于SOA环境及其各种底层技术的动态特性。这种方法将加深我们对反模式的理解，设计和服务质量的SBS，并允许开发的工具，旨在为软件工程师评估和改进的设计和服务质量的SBS处理的最终用户，并减轻他们的维护和进化任务。
