FLUIDOS Paper Awarded at the 27th Conference on Innovation in Clouds, Internet and Networks

We are thrilled to announce a significant achievement for the FLUIDOS consortium. The research paper titled “Cost Minimization in Multi-cloud Systems with Runtime Microservice Re-orchestration” authored by Marco Zambianco, Silvio Cretti, and Domenico Siracusa, has been recognized with the Best Paper Award at the 27th Conference on Innovation in Clouds, Internet and Networks (ICIN) that took place in Paris, France on March 11-14, 2024.

Innovation in multi-cloud deployments
The honoured paper addresses a critical challenge in the realm of cloud computing, that of optimising costs in multi-cloud infrastructures. As businesses increasingly rely on cloud services from multiple providers, managing expenses while ensuring efficient service delivery becomes paramount. The paper introduces an innovative approach to minimise deployment costs by dynamically reallocating microservices across different cloud environments. This strategy significantly reduces the economic burden on enterprises by optimising resource utilisation and minimising service disruptions.

Key insights and methodologies
The study highlights the complexity of maintaining cost efficiency in multi-cloud systems that lease virtual compute resources from various providers with different pricing models. Traditional deployment strategies often lead to significant resource fragmentation and higher operational costs. The authors propose a novel re-orchestration scheme that facilitates the migration of microservices at runtime. This approach leverages a rolling update scheduling logic, allowing for the seamless reallocation of services without the need to halt and redeploy applications, thereby ensuring continuous operation.

Central to the paper is the development of an integer linear optimization problem designed to minimise costs associated with virtual cloud nodes while prioritising the co-location of delay-sensitive microservices on the same regional cluster. The proposed solution not only promises reduced deployment expenses but also minimal service disruption and quality of service (QoS) violations, outperforming standard Kubernetes-based deployment strategies.

A step forward
This award-winning paper contributes to cloud computing by addressing a specific challenge with a practical and efficient solution, reflecting FLUIDOS’s ongoing commitment to innovation and its efforts in the field of cloud and Internet network research.
We extend our heartfelt congratulations to the authors for their outstanding contribution and look forward to seeing how their work will continue to shape the future of cloud computing.
