One of the most promising technologies that is raised from the fourth industrial revolution is Digital Twin (DT). A DT captures attributes and behaviors of the entity suitable for communication, storage, interpretation or processing within certain context. A digital twin based on microservice framework architecture is proposed in this paper which identifies elements required for the complete orchestration of microservice based Survival Analysis of Lung Cancer Patients. Integration of microservices and Digital Twin Technology is studied.

본 논문에서는 서로 다른 특성을 갖기 때문에 표준화가 어려운 엣지 플랫폼에서 동일한 머신 러닝 모델로도 확장 가능한 분석 서비스를 하기 위해, 마이크로서비스 기반으로 협업 분석 하는 설계 방법을 소개한다. 이를 위해 실제 사용자 분석 결과 적응적인 컨텐츠 서비스 시나리오를 고려하였다. 서로 다른 성능을 갖는 엣지가 협업하기 위해서 클라우드에서 제공 받는 어플리케이션을 마이크로 서비스화 하고 다수의 엣지에 해당 서비스를 분산 분포하여 연결한다. 해당 방법은 전체 서비스를 상호 독립적인 최소 구성 요소로 분할하고 모든 요소가 독립적으로 연동되어 타스크를 수행하게 하며 유사한 프로세스는 공유함으로서 상대적으로 성능이 떨어지는 엣지들간 협력으로 효율적인 분석 서비스 제공이 가능하도록 할 것이다.

The adoption of cloud environments has revolutionized application deployment and management, with microservices architecture and container technology serving as key enablers of this transformation. However, these advancements have introduced new challenges, particularly the necessity to precisely understand service interactions and conduct detailed analyses of internal processes within complex service environments such as microservices. Traditional monitoring techniques have proven inadequate in effectively analyzing these complex environments, leading to increased interest in eBPF (extended Berkeley Packet Filter) technology as a solution. eBPF is a powerful tool capable of real-time event collection and analysis within the Linux kernel, enabling the monitoring of various events, including file system activities within the kernel space. This paper proposes a container activity analysis system based on eBPF, which monitors events occurring in the kernel space of both containers and host systems in real-time and analyzes the collected data. Furthermore, this paper conducts a comparative analysis of prominent eBPF-based container monitoring systems (Tetragon, Falco, and Tracee), focusing on aspects such as event detection methods, default policy application, event type identification, and system call blocking and alert generation. Through this evaluation, the paper identifies the strengths and weaknesses of each system and determines the necessary features for effective container process monitoring and restriction. In addition, the proposed system is evaluated in terms of container metadata collection, internal activity monitoring, and system metadata integration, and the effectiveness and future potential of eBPF-based monitoring systems.
