Serverless computing promises cost-efficiency and elasticity for high-productive software development. To achieve this, the serverless computing platform must address two challenges: strong isolation between function instances, and low startup latency to ensure user experience. In this talk, I will first present a characterization of state-of-the-art serverless platform and derive several key metrics, which collectly forms a systematic methodology and a benchmark called severlessbench. Then, I will show how severless platform can be optimized for (sub-)millisecond startup latency for both normal and condential severless computing. Finally, I will present an outlook on challenges and opportunities of serverless comptuting, including how to make it secure and efficient for joint cloud computing.
