Online Robust Placement of Service Chains for Large Data Center Topologies
The trend today is to deploy applications and more generally Service Function Chains (SFCs) in public clouds. However, before being deployed in the cloud, chains were deployed on dedicated infrastructures where software, hardware, and network components were managed by the same entity, making it straightforward to provide robustness guarantees. By moving their services to the cloud, the users lose their control on the infrastructure and hence on the robustness. Thus, in our work, we introduce an online algorithm for robust placement of service chains in data centers. Our placement algorithm determines the required number of replicas for each function of the chain and their placement in the data center.
Mapping the Human Brain
Exploring the complexity of the human brain is a challenge that nowadays is tackled by scientists from every field from medicine to mathematics. In this talk I will show how it is possible to locally reconstruct the anatomy of the human brain and how this opens the possibility to study the whole brain as a network called connectome. Finally I will introduce some problem in brain connectivity estimation and analysis.
