A Survey on Serverless Computing and Its Implications for JointCloud Computing

Serverless computing is known as an appealing alternative cloud computing paradigm with its auto-scaling nature and pay-as-you-go charging model. Mainstream cloud vendors have proposed their own serverless platforms, while various kinds of applications have been refactored in a serverless manner for execution. However, the serverless computing model still entails refinement as it introduces performance and security issues. In this paper, we conduct a comprehensive survey on the serverless computing, mainly in three aspects: the type of applications suitable for serverless, the performance issues, and the security issues. We specifically elaborate previous efforts on resolving issues in serverless and shed light on the unresolved issues. We also discuss the opportunities and challenges in integrating serverless computing in the jointcloud infrastructure.
