Taming the cloud: Safety, certification and compliance for software services - Keynote at the Workshop on Engineering Service-Oriented Applications (WESOA) 2011

The maturity of IT processes, such as software development, can be and is often certified. Current trends in the IT industry suggest that software systems in the future will be very different from their counterparts today, with an increasing adoption of the Service-Oriented Architecture (SOA) design pattern and the deployment of Software-as-a-Service (SaaS) on Cloud infrastructures. In this talk we discuss some issues surrounding engineering Software Services for Cloud infrastructures and highlight the need for enhanced control, service-level agreement and compliance mechanisms for Software Services. Cloud Infrastructures and Service Mash-ups

Proposing a Delphi-derived, inter-enterprise service-oriented architecture maturity model

Companies have long sought to integrate existing Information Systems (IS) in order to support existing and potentially new business processes spread throughout their “territories” and possibly to collaborating organizations. A variety of designs can be used to this end, ranging from rigid point-to-point electronic data interchange (EDI) interactions to “Web auctions”. By updating older technologies, such as “Internet-enabling” EDI-based systems, companies can make their IT systems available to internal or external customers; but the resulting systems have not proven to be flexible enough to meet business demands. A more flexible, standardized architecture is required to better support the connection of various applications and the sharing of data. Service- Oriented Architecture (SOA) is one such architecture. It unifies (“orchestrates”) business processes by structuring large applications as an ad-hoc collection of smaller modules called “Services”. These applications can be used by different groups of people both inside and outside the company, and new applications built from a mix of services (located in a global repository) exhibit greater agility and uniformity

A comparative study of service-oriented architecture maturity model

Service-oriented Architecture (SOA) maturity model is a benchmark for evaluating and assessing the maturity of SOA adoption. Several of SOA maturity models have been constructed by the academia and industry.However, these models contradict with each other in determining “what” need to be assessed in SOA adoption.Therefore, the aims of this study is to review and compare the existing SOA maturity models that were commonly referred such as SOAMM, SIMM, CSOAMM, Inaganti’s Model, iSOAMM, Welke’s Model and SOASMM in order to determine which model should be enhanced to reflect the true definition of SOA. The findings implies that the existing models have their own strengths and weaknesses and based on these findings, this study identify that Welke’s model is the most suitable model that should be enhanced. This study has successfully analyze the existing models and identify an issue that deserve future investigation such as the need to provide two dimensional evaluations for both IT benefits and business benefits and the need to improve the evaluation processes in the SOA maturity model

Evaluation of service-oriented architecture adoption maturity model for sustainable development

Goal-oriented evaluation is a fundamental approach to monitor and ensure that all measurement activities are being carried out in the context of a well-defined evaluation goal. However, this study found that the previous ServiceOriented Architecture maturity models have not comprehensively considered providing an appropriate method for evaluating the Service-Oriented Architecture adoption. Therefore, this study aims to provide an evaluation method for Service-Oriented Architecture adoption by using goal-oriented approach. The reason is that in order for the evaluation to be effective, it must be driven by a goal. Thus, this study adapts the goal-oriented approach in order to provide an effective evaluation method for evaluating the Service-Oriented Architecture adoption. This study also extends the metric component in Goal-Question-Metric by providing a scale for each metric based on the NPLF rating scale adapted from ISO/IEC 15504. Conclusively, this paper has shown that goaloriented approach can be used to evaluate the Service-Oriented Architecture adoption through Goal-Question-Metric. GoalQuestion-Metric also provides a hierarchical structure that can be refined in order to evaluate the SOA adoption towards a sustainable development effectively. Sustainable development means that the teams work at consistence and continuous speed to produce a quality result. Therefore, the proposed model may benefit the Service-Oriented Architecture practitioner and quality editor in software engineering domain

A construction of service-oriented architecture adoption maturity levels using adoption of innovation concept and CMMI

The existing Service-Oriented Architecture (SOA) maturity models constructed their maturity level focuses on the level after the implementation of SOA in the organization. However, less work has been carried out regarding the SOA maturity level that focused on the whole process of SOA adoption including the pre-adoption level. Furthermore, this study also found that less work on constructing the maturity levels for measuring the SOA adoption existed. Therefore, this study aims to construct the Service-Oriented Architecture adoption maturity level by combining the adoption of innovation concept with Capability Maturity Model Integration (CMMI). This study constructs the lower level of the proposed SOA adoption maturity level based on the adoption of innovation concept and the upper level based on CMMI and the existing SOA maturity models. This study has successfully shown that the adoption of innovation concept can be combined with CMMI in order to construct a holistic maturity level for evaluating the SOA adoption. This level covers the whole SOA adoption processes ranging from the pre-adoption level up to the optimized level. This study also aims at evaluating the SOA adoption toward sustainable development. Sustainable development means that the teams work at consistence and continuous speed to produce a quality result. Thus, the proposed maturity level may benefit the SOA practitioner and software quality assurance in software engineering domain

The Implementation of Service-Oriented Architectures in the German Banking Industry - A Case Study

The concept of Service-oriented Architecture (SOA) is becoming increasingly important not only in research, but also in practice. SOA has emerged as a major topic, especially in regards to the banking industry as it is one of the cutting-edge industries concerning service-orientation. SOA implementation in the German banking industry varies, with some still in the adoption phase and others already in the SOA operations phase. This has specific implications concerning the SOA Readiness as well as the SOA Maturity of German banks. This paper details the research objective, design, and conduction of a case study in the Germany banking industry investigating the SOA Readiness and SOA Maturity of German banks. Different phases such as SOA adoption and SOA operations and the consequences of SOA during Merger & Acquisition (M&A) conduction are analyzed and evaluated. Finally, the preliminary findings are exhibited

A conceptual model for service-oriented architecture adoption maturity model

Service-oriented architecture (SOA) maturity model is a model that can be used to guide the SOA adoption.There are several SOA maturity models that have been constructed by the previous researchers.However, most of the existing models are focused on what to evaluate rather than how to perform the evaluation.Therefore, the aim of this study is to propose a conceptual model for SOA adoption maturity evaluation.This study reviewed and investigated the existing models in order to identify the issues and current implementation of the SOA maturity model.The findings implied that there is a lack of SOA maturity models that evaluated on the SOA adoption and focused specifically on both IT and business benefits.Furthermore, the existing models also do not provide any details on how to evaluate the maturity of SOA adoption. As a result, this study proposed a conceptual model for SOA adoption maturity evaluation that also consist of a tool to assess the maturity of SOA adoption

From service-oriented architecture to service-oriented enterprise

Service-Oriented Architecture (SOA) was originally motivated by enterprise demands for better business-technology alignment and higher flexibility and reuse. SOA evolved from an initial set of ideas and principles to Web services (WS) standards now widely accepted by industry. The next phase of SOA development is concerned with a scalable, reliable and secure infrastructure based on these standards, and guidelines, methods and techniques for developing and maintaining service delivery in dynamic enterprise settings. In this paper we discuss the principles and main elements of SOA. We then present an overview of WS standards. And finally we come back to the original motivation for SOA, and how these can be realized
