The Gap Between Serverless Research and Real-world Systems

With the emergence of the serverless computing paradigm in the cloud, researchers have explored many challenges of serverless systems and proposed solutions such as snapshot-based booting. However, we have noticed that some of these optimizations are based on oversimplified assumptions that lead to infeasibility and hide real-world issues. This paper aims to analyze the gap between current serverless research and real-world systems from a perspective of industry, and present new observations, challenges, opportunities, and insights that may address the discrepancies.
