Special Issue Information

Dear Colleagues,

With the advent of the Internet of Things (IoT), the centralised cloud computing service delivery paradigm has been gradually transformed into a cloud continuum that includes edge and fog computing and heterogeneous IoT devices with varying computing and power capabilities. At the same time, the dawn of the 5G era demands advanced orchestration solutions that can meet the time- and mission-critical requirements of IoT-enabled applications.

However, several challenges still need to be addressed regarding these capabilities. The orchestration of such complex applications requires, for example, heterogeneous resources spread across the cloud continuum. The core advantage of edge computing is the placement of computational resources at the network edge to alleviate the computation burden of IoT devices, which are also augmented with enhanced computational capabilities. In this context, orchestrating such applications requires solutions for distributed service embedding, task offloading, resource autoscaling, and service migration in a real-time and scalable manner. With the evolution of the IoT and the advent of 5G/6G and massive machine-type communications, extremely dense networks are expected to be created, placing even more strain on the available infrastructure across the cloud continuum.

With this context in mind, this Special Issue invites novel conceptual, theoretical, and experimental contributions addressing the unresolved challenges in the area of the cloud continuum, the IoT, and AI. The topics of interest include, but are not limited to the following:

  • Resource allocation and scheduling in the cloud continuum;
  • Virtual network embedding in the cloud continuum;
  • Scalability issues in the cloud continuum;
  • Novel architectures in the cloud continuum;
  • AI for QoS management in cloud continuum.
  • task offloading in the cloud continuum;
  • Energy sustainability in the cloud continuum;
  • Digital twins in the cloud continuum;
  • Network/resource monitoring in the cloud continuum;
  • Computation and network infrastructure resilience and reliability;
  • Virtualization solutions for distributed application deployment in the cloud continuum;
  • Security issues in the cloud continuum;
  • Architectures for digital forensics;
  • Data analytics, traffic analysis, and classification in the cloud continuum;
  • Testbeds and experimental facilities report.

Digital forensics systems are complex applications consisting of numerous individual components that demand substantial computing resources. By adopting the concept of microservices, forensics applications can be divided into smaller, independently managed services. In this context, cloud resource orchestration platforms like Kubernetes provide augmented functionalities, such as resource scaling, load balancing, and monitoring, supporting every stage of the application’s lifecycle. This article explores the deployment of digital forensics applications over a microservice-based architecture. Leveraging resource scaling and persistent storage mechanisms, we introduce a vertical scaling mechanism for compute-intensive forensics applications. A practical evaluation of digital forensics applications in competition investigations was performed using datasets from the private cloud of the Hellenic Competition Commission. The numerical results illustrate that the processing time of CPU-intensive tasks is reduced significantly using dynamic resource scaling, while data integrity and security requirements are fulfilled.
