Avaliação da técnica de snapshotting para mitigar os efeitos do cold start de funções Javascript executados em ambiente FaaS.

Abstract

The serverless computing model allows the creation and execution of applications in the cloud, delegating to the platform the responsibility for managing and scaling the infrastructure. As a result, billing for services considers only the execution time of requests, naturally resulting in efficient use of resources. This strategy aims to reduce the costs of keeping services running, but it comes with a burden: starting applications takes time (cold start), and doing this whenever the application is requested can be a hindrance to their performance, especially in a highly scalable environment. The Prebaking technique emerges as a solution to this problem, using the method of snapshotting the state of a process to deal with the cold start, obtaining good results for applications created in Java. In this direction, this work aims to evaluate the use of this method to reduce the cold start of Javascript applications that use the V8 runtime.
