The adoption of virtualization in edge computing promotes the use of numerous applications and operating systems on a single physical server. The technological environment is increasingly efficient, economical, and hassle-free by virtue of this technology. This study explores the potential of virtualization in edge computing environments by creating virtual versions of physical resources and services. The primary objective of this study is to reduce hardware and operational expenses by consolidating multiple systems into one physical system. Various deployment strategies for virtual machines on edge nodes, including containers, hypervisors, and virtual machines, are discussed. The article also delves into a virtualization-based framework to address challenges in edge computing. Additionally, through historical research on virtualization techniques, this article provides insights into the benefits and limitations of virtualization in edge computing. Moreover, the integration of virtualization and edge computing is examined, highlighting open challenges that need to be addressed for optimal utilization of virtualization in edge computing environments. The findings contribute to a deeper understanding of the possibilities and challenges associated with virtualization in edge computing environments, laying the foundation for further research in this field.

The micro cloud model offers cloud behavior at the edge of the network. It allows dynamic organization of the resources, closer to the users and the data. One of the crucial problems to solve is to design a proper cloud model at the edge of the network and offer cloud services that support multi-tenancy. This cloud property is a governing mechanism to lower cloud costs. It is essential for the scalability of both public and private clouds due to the utilization of shared resources and the logical separation of tenants. This paper presents the model for the creation of virtual clouds (vClouds) on physical infrastructure using a hierarchy of namespaces, with proper organization and redistribution of resources such as CPU, RAM, and storage, while preserving logical isolation between vClouds, thus creating a multi-tenant system. The presented model guarantees accurate resource redistribution through graph transformations to model operations, while the proposed protocols ensure correctness by employing multiparty session types for modeling. We extend the secure computing mode to establish an isolated system, allowing sandboxing rules for every namespace and creating hierarchies of security profiles. This advancement enables our model to inherit parent security profiles fully, extend them by adding child-specific elements, or redefine and create entirely new ones. Furthermore, the users can switch context, meaning they can change vCloud or the namespace they operate on.INDEX TERMS Cloud computing, distributed systems, edge computing, formal specifications, infrastructure as software, platform, namespaces, isolation, multi-tenancy.• We enable users to switch between contexts, meaning they can change vCloud or the namespace they operate on.These advancements rely on our following technical contributions:• Protocol definitions for namespace manipulation:This study defines protocols for performing crucial operations, such as creating, updating, and deleting namespaces within virtual clouds, leveraging the power of rules for graph transformations over namespaces. These protocols provide a standardized framework for managing and manipulating namespaces effectively.

“…In addition to the above advantages, blockchain is evolving towards refinement according to needs. Examples include mechanisms that incorporate artificial intelligence techniques to discriminate behaviors [43], thus identifying, for instance, Ponzi schemes [73]; a peer-to-multipoint approach to data transfer [47]; the introduction of a draft smart contract to create smart digital protocols between blockchain participants [49]; securing payments [50]; security verification, such as identity verification during the COVID-19 epidemic [51]; further refinement of elections and voting [54,62]; penalty mechanisms for malicious behavior of participants [56,57,65,66,68,74]; energy transactions [57]; Internet of Things (IoT) monitoring [60]; anti-fraud functionality implemented using Bitcoin payment platforms before being verified by central aggregators [63]; solving compatibility issues in industrial requirements, generating alerts, processing contracts, events, and certificates [64]; proving ownership of customers/healthcare providers [65]; combining other technologies such as artificial intelligence [44], proposing new blockchain paradigms [67] and interoperability with emerging progressive technologies within the blockchain, such as decentralized prophecy machines and sidechains [74]; enhancing the searchability of information within the blockchain [69]; using smart contracts to control the process [75]; using a shapley-valued profit-sharing mechanism [77]; supervisory functions shared by all nodes [47,70]; and no dependence on third-party organizations [50,63,69].…”

Faced with the impact of the coronavirus disease (COVID-19) pandemic, governments must protect the well-being of the population. Aside from considerations, such as keeping the virus from spreading and treating patients, the government should also be concerned about the mental health of its citizens during the epidemic. This study aimed to help users who develop depression due to COVID-19 on social media, reduce the cost of counselling, and reduce the need for users to visit the hospital for counselling. This study investigated the opportunities for blockchain technology to provide psychological help to social media users suffering from depression caused by the pandemic. Blockchain-based technology has been used to develop a new model that enables a user autonomy system to allow users to control their own data fully. The model utilizes a delegated proof of stake consensus blockchain to manage depression data to enable low cost and information security while discussing aspects related to trust, privacy, interoperability, and integration with other information communication technologies. The blockchain framework has been proven to provide secure and reliable information management that meets the user requirements for information autonomy. The framework can be combined with various other information technologies to extend its functionality further. Blockchain, privacy, user autonomy, depression, social media. INDEX TERMS
