OPTIMIS: A holistic approach to cloud service provisioning
Ana Juan Ferrer,Francisco Guevara Hernández,Johan Tordsson,Erik Elmroth,Ahmed Ali-Eldin,Csilla Zsigri,Raül Sirvent,Jordi Guitart,Rosa M. Badia,Karim Djemame,Wolfgang Ziegler,Theo Dimitrakos,Srijith K. Nair,George Kousiouris,Kleopatra Konstanteli,Theodora Varvarigou,Benoit Hudzia,Alexander Kipp,Stefan Wesner,Marcelo Corrales,Nikolaus Forgó,Tabassum Sharif,Craig Sheridan +22 more
TL;DR: By addressing the whole service life cycle, taking into account several cloud architectures, and by taking a holistic approach to sustainable service provisioning, the toolkit aims to provide a foundation for a reliable, sustainable, and trustful cloud computing industry.
Proceedings ArticleDOI
An adaptive hybrid elasticity controller for cloud infrastructures
TL;DR: This paper focuses on horizontal elasticity, the ability of the infrastructure to add or remove virtual machines allocated to a service deployed in the cloud, and builds two adaptive proactive controllers that estimate the future load on a service using queuing theory.
BookDOI
Self-management Challenges for Multi-cloud Architectures (Invited Paper)
Erik Elmroth,Johan Tordsson,Francisco Guevara Hernández,Ahmed Ali-Eldin,Petter Svärd,Mina Sedaghat,Wubin Li +6 more
TL;DR: This work focuses on the three complementary cloud management problems of predictive elasticity, admission control, and placement (or scheduling) of virtual machines, and proposes an approach to optimize the overall system behavior by policy-tuning for the tools handling each of them.
Proceedings ArticleDOI
Efficient provisioning of bursty scientific workloads on the cloud using adaptive elasticity control
TL;DR: An autonomous elasticity controller is built that changes the number of virtual machines allocated to a service based on both monitored load changes and predictions of future load to construct a hybrid reactive-adaptive controller.
Proceedings ArticleDOI
An Experimental Performance Evaluation of Autoscaling Policies for Complex Workflows
Alexey Ilyushkin,Ahmed Ali-Eldin,Nikolas Herbst,Alessandro Vittorio Papadopoulos,Bogdan Ghit,Dick Epema,Alexandru Iosup +6 more
TL;DR: In this article, the authors present a detailed comparative study of general state-of-the-art autoscaling policies, along with two new workflow-specific policies, and conduct various forms of pairwise and group comparisons.
