Computing Without Borders: The Way Towards Liquid Computing
No full textDespite the de-facto technological uniformity fostered by the cloud and edge computing paradigms, resource fragmentation across isolated clusters hinders the dynamism in application placement, leading to suboptimal performance and operational complexity. Building upon and extending these paradigms, we propose a novel approach envisioning a transparent continuum of resources and services on top of the underlying fragmented infrastructure, called liquid computing. Fully decentralized, multi-ownership-oriented and intent-driven, it enables an overarching abstraction for improved applications execution, while at the same time opening up for new scenarios, including resource sharing and brokering. Following the above vision, we present liqo, an open-source project that materializes this approach through the creation of dynamic and seamless Kubernetes multi-cluster topologies. Extensive experimental evaluations have shown its effectiveness in different contexts, both in terms of Kubernetes overhead and compared to other open-source alternatives
Enabling compute and data sovereignty with infrastructure-level data spaces
No full textData is a critical asset in today's world. When multiple actors are involved, ensuring that data is accessible only to authorized parties and protecting it against theft present significant challenges. A potential solution to these issues is creating data spaces that interconnect clusters managed by different actors. The latter can securely exchange data under specific constraints and terminate connections when needed. This paper aims to show how infrastructure-level data spaces, which support both access to data, and processing of it, can facilitate secure data exchange and limit data theft. Furthermore, we investigate how data sovereignty can be maintained through cluster data exchange, which is crucial in an era where data is increasingly regulated and controlled. Additionally, we explore how offloading applications from the data consumer into the data producer cluster can match data gravity patterns, improving overall system efficiency. Finally, this paper presents the potential integration of the proposed solution within the framework of IDSA and Gaia-X, serving as promising option for implementing their proposed functionalities
Vernacular Authorship in Late Medieval Religious Discourse. The Case of William Flete’s <em>Remedies against Temptations</em>
No full textDespite the fact that the main topic of William Flete’s Remedies against Temptations was a pivotal concern of late medieval spiritual literature and the treatise in letter form was widely circulated in both Latin and English, it has remained rather marginal to critical discourse. Neither epistolary space as the site of interaction author/audience nor the role of spiritual authorities in establishing themselves as real authors of religious texts as distinguished from compilers and scribes have been specifically investigated. The paper focuses on the dialogic construction of the authorial voice in William Flete’s Remedies against Temptations through the analysis of the linguistic and discursive strategies used in the vernacular version of this work of spiritual advice. The most relevant strategy is the choice of the letter format to address a female audience as it allows to transfer authoritative religious discourse into English and to assert the writer’s status of author of a text addressed to both religious women and the lay public. In addition, the paper aims at highlighting the relevance of stylistic analysis to delineate the construction of the textual vernacular author in the context of audience recognition. In addressing a non-academic public, the author of one of the English versions of Remedies against Temptations engages with Latin learning and asserts himself as the author of a vernacular theology text
