Recent years have witnessed increasing demand for real-time cloud services to support Internet of Things and other time-critical applications. However, existing virtualization and cloud technologies cannot provide latency guarantees due to the lack of real-time support across the software stack. This talk will introduce our effort to bring real-time performance to cloud computing through three thrusts: (1) RT-Xen, a real-time virtual machine scheduling framework incorporated in the Xen hypervisor; (2) VATC, a virtualization-aware traffic control system for real-time network I/O in virtualized hosts; and (3) RT-OpenStack, a cloud CPU resource manager that provides real-time performance guarantees to virtual machines, while allowing non-real-time virtual machines to fully utilize remaining CPU resources. This project represents promising steps toward a real-time cloud infrastructure for Internet of Things and time-critical applications.
