Disaggregated Virtualization
— Preview
Study of new virtualisation mechanisms adapted to a disaggregated cloud infrastructure and to a cloud infrastructure made up of small edge infrastructures connected to powerful data centres.
Gaël Thomas, Inria Senior Researcher
Keywords : Disaggregation, edge, virtualisation
Data centers are evolving with the arrival of disaggregated and edge infrastructures. The aim of the DiVA project is to prepare the system stack for these next-generation infrastructures, in order to make more efficient use of hardware resources.
In the context of disaggregated infrastructures, it is becoming possible, on the scale of a cluster of machines, to fully mutualize hardware resources. This evolution requires us to revisit virtualization mechanisms, as virtual machines become elastic (new resources can be added to a virtual machine on the fly) and distributed (the hardware resources used by a virtual machine are physically distributed).
In the context of edge infrastructures, small clusters of machines are connected by slow networks to powerful data centers. Edge clusters perform computations close to data sources, while still being able to use the computing power of a data center. This evolution requires us to revisit several system mechanisms, as infrastructures become much more heterogeneous in terms of hardware, network and software architecture.
