This study addresses the unpredictable end-to-end latency in cloud virtualized environments, which stems from virtualization overheads in CPU, I/O, and network resources. Through systematic network measurement experiments across diverse virtualization platforms—including KVM, LXC, and Docker—under multidimensional workload conditions, the authors collect packet round-trip time data to construct a high-quality dataset suitable for machine learning–based network performance modeling. By integrating data preprocessing, correlation analysis, dimensionality reduction, and clustering techniques, this work presents the first quantitative evaluation of latency impacts across multiple virtualization technologies. The resulting dataset effectively supports network performance prediction and intelligent resource scheduling, providing an empirical foundation for performance optimization in cloud environments.

This study addresses the practical disparities and co-evolution between high-performance computing (HPC) and edge computing architectures within the cloud continuum. It presents the first large-scale empirical analysis based on 396 real-world, production-grade AWS architectures. Methodologically, we propose a multidimensional, data-driven framework encompassing service topology identification, storage type classification, architectural complexity quantification, and ML service integration statistics. Results reveal systematic differences—and complementary patterns—between HPC and edge architectures across four dimensions: core service composition (e.g., EC2 versus Greengrass/Lambda), storage design paradigms (parallel file systems versus distributed lightweight caches), complexity distributions, and ML embedding strategies. This work delivers the first industry-scale architectural benchmark for the cloud continuum, providing empirically grounded insights and methodological foundations for cross-domain architecture design, resource optimization, and cloud-native convergence of HPC and edge computing.

This work addresses the challenges of resource utilization and operational efficiency in microservice architectures by proposing a performance-metric-driven automated framework that intelligently determines the optimal deployment strategy for individual microservices between Infrastructure-as-a-Service (IaaS) and Function-as-a-Service (FaaS). By analyzing intrinsic microservice characteristics, the framework enables a scalable and reproducible migration from conventional IaaS deployments to a hybrid IaaS+FaaS model. Experimental evaluation on two real-world applications demonstrates that the approach accurately identifies microservices well-suited for serverless execution, significantly improving both deployment efficiency and resource utilization. Furthermore, the study clarifies the respective applicability boundaries and advantages of different cloud service models, offering practical guidance for architecture design in heterogeneous cloud environments.

This study addresses prolonged task completion times, low resource utilization, and high resource release latency in Docker/Kubernetes containers on cloud-native platforms running compute-intensive workloads (e.g., big data and deep learning). We systematically evaluate the performance impact of diverse resource scheduling strategies through system-level monitoring—leveraging cgroups and metrics-server—and multi-workload stress testing. For the first time, we empirically quantify how key resource configurations significantly affect task completion time (±79.4% variation) and resource release latency (+116.7% degradation). Based on these findings, we propose an evidence-driven configuration optimization paradigm that reduces maximum task completion time by up to 79.4% and precisely identifies configuration bottlenecks responsible for latency. Our results provide reproducible, transferable empirical foundations for resource management tuning and deployment decisions in cloud-native environments.

Research on containerization in multi-cloud environments remains fragmented, lacking a systematic, up-to-date synthesis. Method: We conduct a Systematic Mapping Study (SMS) spanning 2013–2024, analyzing 121 high-quality publications through bibliometric analysis, thematic coding, and ISO/IEC 25010 quality attribute modeling. Contribution/Results: We propose the first four-level classification framework—“Theme–Strategy–Quality Attribute–Tactic”—identifying four core research themes, 98 implementation strategies, 10 critical quality attributes, and 47 corresponding architectural tactics. Innovatively, we introduce a two-dimensional challenge-solution taxonomy organized along Security, Automation, Deployment, and Monitoring dimensions. This yields the first structured, reusable landscape of multi-cloud containerization, bridging theoretical research and industrial practice by supporting architecture design and technology selection—thereby addressing a longstanding gap in systematic knowledge integration for this domain.

This study addresses the infrastructure complexity of cloud-edge-end协同 architectures, which has emerged as a major bottleneck hindering developer productivity and innovation. Through 101 semi-structured interviews across 86 organizations, this work empirically identifies deployment complexity and onboarding difficulty as core challenges. It proposes four architectural directions to mitigate these issues: Object-as-a-Service (unified object abstraction), internal developer platforms, declarative AI/ML pipelines, and lightweight edge runtimes. Findings indicate that high-level abstractions and automation significantly enhance developer experience—outweighing the impact of execution performance optimizations—and thereby establish a new paradigm for platform engineering and distributed system design.

This study addresses the problem of edge service deployment failures in digital healthcare caused by network outages affecting centralized registries. To mitigate this, we propose a three-tier distributed registry architecture integrating remote public, MEC-private, and LAN-local tiers. By combining edge computing with Docker containerization, the proposed approach enables proximity-aware service orchestration and high-availability distribution. Experimental evaluations demonstrate that under network disconnection scenarios, private and local registries significantly outperform their public counterparts in terms of deployment latency, system load, and energy consumption. These findings indicate that the proposed architecture effectively enhances the fault tolerance and overall resilience of edge services in healthcare environments.

This study addresses the lack of systematic optimization in cloud data pipelines with respect to cost, execution time, and resource utilization, particularly in multi-tenant and industrial settings where research remains limited. Through a comprehensive systematic literature review, the work establishes a unified classification framework for optimization objectives that encompasses both single- and multi-cloud environments as well as batch and stream processing paradigms. The analysis synthesizes existing approaches and identifies critical research gaps, including insufficient support for multi-tenancy, inadequate multi-cloud coordination, and a scarcity of real-world deployment validation. By clarifying the core objectives and technical pathways for optimizing cloud data pipelines, this paper provides a theoretical foundation and clear direction for future research in this domain.

This work addresses the scalability bottlenecks and the inherent trade-off between high availability and load balancing in traditional cloud IaaS virtual networks under multi-tenant environments. To overcome these limitations, the authors propose a fully distributed virtual network architecture that eliminates centralized control and data planes by leveraging per-host agents. The design supports VLAN-based isolation for up to approximately 16.7 million tenants, accommodates large IP subnets per tenant, and provides SNAT/DNAT services without throughput bottlenecks—all while preserving large Layer 2 semantics and eliminating single points of failure. Prototype evaluation demonstrates that the proposed architecture achieves high availability, efficient load balancing, and elastic scalability to large-scale deployments, significantly enhancing the performance and reliability of multi-tenant virtual networks.
