Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents current research in the design and integration of advance systems, service and management technologies into a new generation of Service Infrastructure for Future Internet of Services, which includes Service Clouds Computing. These developments are part of the FP7 RESERVOIR project and represent a creative mixture of service and network virtualisation, service computing, network and service management techniques.

The reservoir model and architecture for open federated cloud computing
- 2009

Tidskriftsartikel (refereegranskat)abstract
- The emerging cloud-computing paradigm is rapidly gaining momentum as an alternative to traditional IT (information technology). However, contemporary cloud-computing offerings are primarily targeted for Web 2.0-style applications. Only recently have they begun to address the requirements of enterprise solutions, such as support for infrastructure service-level agreements. To address the challenges and deficiencies in the current state of the art, we propose a modular, extensible cloud architecture with intrinsic support for business service management and the federation of clouds. The goal is to facilitate an open, service-based online economy in which resources and services are transparently provisioned and managed across clouds on an on-demand basis at competitive costs with high-quality service. The Reservoir project is motivated by the vision of implementing an architecture that would enable providers of cloud infrastructure to dynamically partner with each other to create a seemingly infinite pool of IT resources while fully preserving their individual autonomy in making technological and business management decisions. To this end, Reservoir could leverage and extend the advantages of virtualization and embed autonomous management in the infrastructure. At the same time, the Reservoir approach aims to achieve a very ambitious goal: creating a foundation for next-generation enterprise-grade cloud computing.

Cloud brokering mechanisms for optimized placement of virtual machines across multiple providers
- 2012

Tidskriftsartikel (refereegranskat)abstract
- In the past few years, we have witnessed the proliferation of a heterogeneous ecosystem of cloud providers, each one with a different infrastructure offer and pricing policy. We explore this heterogeneity in a novel cloud brokering approach that optimizes placement of virtual infrastructures across multiple clouds and also abstracts the deployment and management of infrastructure components in these clouds. The feasibility of our approach is evaluated in a high throughput computing cluster case study. Experimental results confirm that multi-cloud deployment provides better performance and lower costs compared to the usage of a single cloud only.

COGNIT: challenges and vision for a serverless and multi-provider cognitive cloud-edge continuum
- 2023
-
Ingår i: 2023 IEEE International Conference on Edge Computing and Communications (EDGE). - : IEEE. - 9798350304831 - 9798350304848 ; , s. 12-22

Konferensbidrag (refereegranskat)abstract
- Use of the serverless paradigm in cloud application development is growing rapidly, primarily driven by its promise to free developers from the responsibility of provisioning, operating, and scaling the underlying infrastructure. However, modern cloud-edge infrastructures are characterized by large numbers of disparate providers, constrained resource devices, platform heterogeneity, infrastructural dynamicity, and the need to orchestrate geographically distributed nodes and devices over public networks. This presents significant management complexity that must be addressed if serverless technologies are to be used in production systems. This position paper introduces COGNIT, a major new European initiative aiming to integrate AI technology into cloud-edge management systems to create a Cognitive Cloud reference framework and associated tools for serverless computing at the edge. COGNIT aims to: 1) support an innovative new serverless paradigm for edge application management and enhanced digital sovereignty for users and developers; 2) enable on-demand deployment of large-scale, highly distributed and self-adaptive serverless environments using existing cloud resources; 3) optimize data placement according to changes in energy efficiency heuristics and application demands and behavior; 4) enable secure and trusted execution of serverless runtimes. We identify and discuss seven research challenges related to the integration of serverless technologies with multi-provider Edge infrastructures and present our vision for how these challenges can be solved. We introduce a high-level view of our reference architecture for serverless cloud-edge continuum systems, and detail four motivating real-world use cases that will be used for validation, drawing from domains within Smart Cities, Agriculture and Environment, Energy, and Cybersecurity.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- There has been a considerable discussion in the past years on the similarities and differences between Clouds and Grid Computing. This included extreme positions whether Clouds are a pure marketing hype, or whether Grids became obsoleted by failing a wide commercial adoption as a resource sharing platform. Now, we can assess that neither is true nor necessary. Grids and clouds share many similarities as they both address questions concerning access to resources in a large-scale distributed environment. Thus, there is significant overlap between the two areas in the ways that infrastructures may evolve.
