Explore the innovative QuarkContainers technology for high-performance secure containers in serverless computing. Discover how this open-source solution addresses the limitations of current Runc container runtimes by providing strong isolation, minimal overhead, sub-100ms startup times, and negligible performance degradation. Learn about the implementation of an application kernel using KVM in Rust, the utilization of io_uring and RDMA to enhance I/O and network performance, and the "Hibernating" technique for accelerating container startup. Gain insights into the integration of QuarkContainers with Kuasar to eliminate shim processes, ultimately improving efficiency and scalability in serverless environments.
