The Second Workshop on Seamless Adaptive Multi-cloud Management of Service-based Applications took place on September 15th, 2015 in Taormina, co-located with the Fourth European Conference on Service-Oriented and Cloud Computing (ESOCC). The workshop was jointly organized by the CloudWave and SeaClouds ( www.seaclouds-project.eu) European FP7 projects, represented by Dr. Francesco Longo and Prof. Ernesto Pimental, respectively.
The program of the workshop edition included an opening session with a brief discussion about cloud-focused European projects and the future of ICT in Europe. One of the conclusions of such a discussion, also inspired by the earlier plenary round table organized within the main conference, is that startups and university spin-offs represent a precious resource for future European projects providing use cases and real business scenarios.
There was also an invited talk from Lan Wang (Imperial College, London) about "Cognitive Packet Network for Self-Aware Adaptive Clouds". The talk was indeed very interesting, focusing on the use of neural networks as a tool for intelligent and adaptive scheduling policies in cloud computing.
After the talk, 4 papers were presented: 3 regular papers, and 1 short paper (on-going work).
The short paper, “Supporting Cloud Service Selection with a Risk-driven Cost-benefit Analysis” proposed a practical and simple approach to choosing a concrete cloud service (or a set of thereof) when several alternatives are available.
The paper "Axe: A Novel Approach for Generic, Flexible, and Comprehensive Monitoring and Adaptation of Cross-Cloud Applications" introduced a novel approach to monitoring and adaptation management that is able to flexibly gather various monitoring data from virtual machines distributed across cloud providers, to dynamically aggregate the data in the cheapest possible manner, and finally, to evaluate the processed data in order to adapt the application according to user-defined rules.
The paper "A Model-Based Approach for the Pragmatic Deployment of Service Choreographies" discussed the problem of managing multiple choreographies in multi-cloud
environments and advocated that sharing-aware deployment is a more effective and resource-efficient approach.
Finally, the paper "Multi-level adaptations in a CloudWave infrastructure: a Telco Use Case" described the CloudWave telecommunications application use case providing a proof-of-concept on how the QoS experienced by the application users can be improved thanks to the technologies provided by CloudWave.
The workshop concluded with a final wrap-up session highlighting how adaptive management of Cloud infrastructures still represents a hot and promising topic as demonstrated by the number of submission and the high quality of the accepted papers. The organizers of the workshop are looking towards a third edition next year.
We would like to thank all the members of the Program Committee for their availability and for the interesting discussions we made during the paper review process. Thanks also to the supporting authors who sent their contributions. Finally, we would also like to thank ESOCC organizers for the help they provide us with the workshop organization.
