Containers are a lightweight cloud infrastructure deployment technology that has gained unprecedented popularity due to their flexible portability, low overhead, and resources elasticity. Leveraging containerization as an alternative to virtualization, various applications dependencies may be deployed in a self-contained piece with separated binary and library files. Hence, this alternative has been suggested as a suitable option for more interoperable application packaging in the edge, fog, or cloud systems. With the rising focus on container-based virtualization, the need to investigate the implementation and orchestration of containerized clusters has emerged as a key research issue. To fill this gap, this paper seeks to systematically consolidate the existing literature following the trend of three research areas observed over years. The first research area englobes an overview on the key prerequisites that a standard federated containerized architecture must meet, followed by some prominent containers use cases. The second research area focuses then on a performance comparison of various container solutions with regard to hypervisor technologies and bare-metal deployment. Eventually, containers infrastructure scheduling techniques are discussed as a third research area in the form of a granular insight into resource allocation and auto-scaling policies. © The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd. 2024.

In this study, we investigated the performance improvement caused by the addition of copper(Cu)nanoparticles to high-density polyethylene(HDPE) matrix material. Composite materials, with filler percentages of 0.0, 2.0, 4.0, 6.0, 8.0, and 10.0 wt% were synthesized through the material extrusion(MEX)3D printing technique. The synthesized nanocomposite filaments were utilized for the manufacturing of specimens suitable for the experimental procedure that followed. Hence, we were able to systematically investigate their tensile, flexural, impact, and microhardness properties through various mechanical tests that were conducted according to the corresponding standards. Broadband Dielectric Spectroscopy was used to investigate the electrical/dielectric properties of the composites. Moreover, by employing means of Raman spectroscopy and thermogravimetric analysis(TGA) we were also able to further investigate their vibrational, structural, and thermal properties. Concomitantly, means of scanning electron microscopy(SEM), as well as atomic force microscopy(AFM), were used for the examination of the morphological and structural characteristics of the synthesized specimens, while energy-dispersive Xray spectroscopy(EDS) was also performed in order to receive a more detailed picture on the structural characteristics of the various synthesized composites. The corresponding nanomaterials were also assessed for their antibacterial properties regarding Staphylococcus aureus(S. aureus) and Escherichia coli(E. coli) with the assistance of a method named screening agar well diffusion. The results showed that the mechanical properties of HDPE benefited from the utilization of Cu as a filler, as they showed a notable improvement. The specimen of HDPE/Cu 4.0 wt% was the one that presented the highest levels of reinforcement in four out of the seven tested mechanical properties(for example, it exhibited a 36.7%improvement in the flexural strength, compared to the pure matrix).
