“…Yet, the runtime unweaving mechanism depends on the way of how aspects are modelled and woven to software components. For example, if aspects are modelled symmetrically as special components to be bound to functional components through direct binding, runtime (un)weaving is made by means of dynamic reconfiguration of systems; this latter is known to have negative impacts on quality of service (QoS) since dynamic reconfiguration often requires to shut down a part or whole systems for acting; this is unacceptable for critical systems and may cause systems to lose their accumulated states during their execution [39, 40]. Hence the design and weaving mechanism of aspects in ACSD approaches should carefully be chosen to ensure no decline of QoS.…”

Coping with crosscutting and dynamic features of software systems has significant impacts on software modularity, reusability, adaptability, and maintainability. However, dealing with such features is a tremendous challenge for different software paradigms, particularly component-based software development (CBSD) where components can be used as black box software units. Fortunately, dealing with crosscutting features is the main focus of aspect-orientation (AO). To compromise, a plethora of different AO and CBSD combinations are available. There is, however, little consensus on how AO and CBSD can be combined and what AO qualities need to be integrated for getting maximum benefits from the combination. In the aim to reach a consensus and increase the understanding of requirements for proper combinations that deal with crosscutting and dynamic features, the authors conduct a domain analysis study of existing combination endeavours; they first identify a set of requirements ought to be fulfilled for proper modelling of crosscutting and dynamic features in component software using AO; second, they group the identified requirements into an evaluation model; third, they check the capability of existing combinations to validate the evaluation model. The study highlighted mandatory requirements for proper combinations and revealed that none of the existing endeavours validates the evaluation model.

“…Microservice architecture (MSA) is a design style that divides large and complex applications into microservices with the core idea of ‘divide and conquer’ rule. As a solution to complex problems, it effectively improves resource utilization, realize the separation of concerns, and make each part of decomposition highly cohesive and loosely coupled (Li & Guo, 2015). With the research on Quality of Service (QoS), MSA shows great potential through the efficient use of cloud resources.…”

Microservice design is a new paradigm of cloud application development. Different from monolithic design, microservice enjoys merits of fine‐grained and loosely coupled services, and it is becoming more and more popular. The application developed with microservice has a good advantage in independent development and flexible deployment, especially for complex distributed systems. However, there is a big gap between the reliability requirements and microservice‐based cloud applications. This article proposes a reliability model of microservice‐based cloud application by using predicate Petri net. First, a microservice reliability requirement is given, some basic concepts of predicate Petri net are defined with syntax and semantics. Second, a microservice reliability strategy is proposed, which uses microservice instances and circuit breaker to improve the reliability of the system. Based on the constructed microservice reliability model, the correctness of predicate Petri net modelling and the effectiveness of the strategies are proven theoretically. Finally, an example is given to illustrate the establishment and analysis process of the model, and several groups of experiments are carried out to verify the effectiveness and feasibility of the method. Experimental results show that the proposed microservice reliability strategy is effective.
