NanoVisor: Revolutionizing FaaS Cold Start Performance with Secure, Lightweight Container Runtime

Explore a groundbreaking conference talk on NanoVisor, a revolutionary container runtime designed to address the challenge of slow cold start times in Function as a Service (FaaS) environments. Discover how NanoVisor, built on gVisor, implements a series of optimizations specifically tailored for FaaS, including lightweight containerd interaction, read-only filesystem, and a sandbox fork mechanism. Learn how these innovations enable the creation of secure, sandboxed containers ready for function execution in just 5ms, with less than 1MB memory overhead per instance and 1.5K QPS per node. Gain insights into NanoVisor's successful application within Ant Group's ecosystem, including Alipay Cloud Base and SOFA Function, as well as its role in CI/CD acceleration. Understand the impact of these advancements on user experience, resource efficiency, and overall FaaS performance.
