  Abstract: A robust, large-scale web service can be difficult to engineer. When demand spikes, it must configure new machines and manage load-balancing; when demand falls, it must shut down idle machines to reduce costs; and when a machine crashes, it must quickly work around the failure without losing data. In recent years, serverless computing, a new cloud computing abstraction, has emerged to help address these challenges. In serverless computing, programmers write serverless functions, and the cloud platform transparently manages the operating system, resource allocation, load-balancing, and fault tolerance. In 2014, Amazon Web Services introduced the first serverless platform, AWS Lambda, and similar abstractions are now available on all major clouds. #R##N#Unfortunately, the serverless computing abstraction exposes several low-level operational details that make it hard for programmers to write and reason about their code. This paper sheds light on this problem by presenting $\lambda_\lambda$, an operational semantics of the essence of serverless computing. Despite being a small core calculus (less than one column), $\lambda_\lambda$ models all the low-level details that serverless functions can observe. To show that $\lambda_\lambda$ is useful, we present three applications. First, to make it easier for programmers to reason about their code, we present a simplified semantics of serverless execution and precisely characterize when the simplified semantics and $\lambda_\lambda$ coincide. Second, we augment $\lambda_\lambda$ with a key-value store, which allows us to reason about stateful serverless functions. Third, since a handful of serverless platforms support serverless function composition, we show how to extend $\lambda_\lambda$ with a composition language. We have implemented this composition language and show that it outperforms prior work.
