The development of microservice systems is complex due to the impact consistency problems have on the business logic design. On the other hand, the implementation of a microservice requires extensive use of middleware technology, which delays the ...

• A highly scalable and available microservice-based digital twin system is proposed.
• A hierarchical and generic digital twin information model is designed.
• The multi-task digital twin model is developed to achieve parallel ...

Digital Twin (DT) is a promising technology that offers versatile services to enhance manufacturing intelligence. However, the agility, reliability and analysis capabilities of existing DT services are severely challenged when applied and ...

Microservices are increasingly used in modern applications, leading to a growing need for effective service composition solutions. However, we argue that traditional API-centric composition mechanisms (e.g., RPC, REST, and Pub/Sub) hamper the modularity ...

Optimizing request routing in large microservice-based applications is difficult, especially when applications span multiple geo-distributed clusters. In this paper, inspired by ideas from network traffic engineering, we propose Service Layer Traffic ...

The Microservice Architecture (MSA) plays a pivotal role in contemporary e-business, promoting service independence, autonomy, and continual evolution in line with the principles of DevOps. However, the distributed nature of the MSA introduces ...

• This paper introduces a new low-code approach, ChatOps4Msa, for ChatOps developers to compose DevOps tool functionalities into new capabilities.
• ChatOps4Msa includes a novel Natural Language Processing (NLP) pipeline leveraging Large ...

Microservice security smells denote possible symptoms of bad design decisions that may compromise the security of an application. Therefore, security smells should be carefully checked and possibly resolved by applying some refactorings. In this ...

Co-locating latency-critical services (LCSs) and best-effort jobs (BEJs) constitute the principal approach for enhancing resource utilization in production clusters. Nevertheless, the co-location practice hurts the performance of LCSs due to ...

The Microservice Architecture emerged as a solution to problems encountered when developing and maintaining a Monolithic system. For this reason, multiple companies migrated their large monolithic applications to a microservices-based system. ...

Microservices are predominant for cloud-based applications, which serve millions of customers daily, that commonly run business-critical systems on software containers and multi-tenant environments; so, it is of utmost importance to secure these ...

• A benchmarking approach for representative/meaningful evaluation of microservice IDSs.
• A methodology for generating representative microservice intrusion detection datasets.
• An instantiation of the benchmark evaluating six ...

Sound static analysis allows one to overapproximate all possible program executions to infer various properties. However, it requires quite some effort to formalize and prove the soundness of program semantics. Most software applications developed ...

Microservice resilience, the ability of microservices to recover from failures and continue providing reliable and responsive services, is crucial for cloud vendors. However, the current practice relies on manually configured rules specific to a certain ...

Remote procedure calls are the workhorse of distributed systems. However, as software engineering trends, such as micro-services and serverless computing, push applications towards ever finer-grained decompositions, the overhead of RPC-based ...

Many organizations implementing DevOps are adopting DORA metrics to measure their capabilities. Surveys are commonly used to gather the DORA metric data. The data are typically captured only in longer intervals, and on the team level, omitting important ...

With the rapid development of cloud computing technologies, cloud-native applications play an increasingly important role in software architecture. However, as applications iterate and evolve, technical debt (TD) can be a critical issue in ...

The increasing use of microservices architecture demonstrates how its emphasis on technological limits and modularity may improve software design and delivery. Nonetheless, difficulties still exist about ownership of microservice, service ...

Microservice architecture became the mainstream for cloud-native systems. While many microservice system benchmarks have been introduced to the scientific community, there is still a notable gap since the benchmarks do not offer architectural ...

This paper presents an industrial case study examining challenges faced by software architects and developers during planning and assessing the correctness of event-driven communication behaviour. We present a novel approach for visualizing the ...

Log anomaly detection is crucial for pinpointing software issues, particularly in large-scale distributed systems where numerous services span multiple machines. Logs are abundant in such environment, meanwhile the log sequences lack inherent ...

Privacy by design is nowadays recognized as essential in bringing data privacy into software systems. However, developers still face many challenges in reconciling privacy and software requirements and implementing privacy protections in software ...

This study aims to address the needs of smart agriculture for agricultural condition monitoring and agricultural production, and builds a multi-source data acquisition and perception technology system based on smart agriculture equipment such as ...
