In cloud computing environments, VMs require fast access to resources like storage and networking. The hardware that the VMs access is implemented in software and/or by passing through a dedicated hardware device. Software-based solutions consume extra CPU cycles, thus resulting in poor performance. Also, these require to expose a device-model to the guest, thus increasing the attack surface. Conversely, hardware passthrough provides better performance and security but can be expensive in terms of the number of physical resources, since each device is dedicated to a single VM. This talk focuses on how Vates is working on sharing hardware resources among VMs by relying on dedicated processors named Data Processing Units (DPU). More precisely, Vates work on offloading Xen hypervisor of storage emulation by relying on Kalray K200 DPU PCIe controllers, a hardware accelerator based on MPPA architecture.
