Formalizing Event-Driven Behavior of Serverless Applications
[article]
2019
arXiv
pre-print
Preserved Fulltext
We present new operational semantics for serverless computing that model the event-driven relationships between serverless functions, as well as their interaction with platforms services such as databases ...
We use these semantics to define the notion of the service call graph for serverless applications that captures program flows through functions and services. ...
-We extend the traditional notion of a call graph with new types of nodes and edges that represent event-driven behavior on serverless platforms. ...

Serverless computing is an approach to cloud computing that allows programmers to run serverless functions in response to external events. ...
Thus serverless functions allow programmers to focus on writing application code, and the cloud provider to manage computing resources globally. ...
Tracing event handlers are a unique feature of Containerless, which is driven by the fact that in typical serverless functions, all "hot paths" include callbacks. ...
