Résumé:
The serverless computing model strengthens the cloud computing tendency to abstract resource management. Serverless platforms are responsible for deploying and scaling the developer’s applications. Serverless also incorporated the pay-as-you-go billing model, which only considers the time spent processing client requests. Such a decision created a natural incentive for improving the platform’s efficient resource usage. This search for efficiency can lead to the cold-start problem, which represents a delay to execute serverless applications. Among the solutions proposed to deal with the cold-start, those based on the snapshot method stand out. Despite the rich exploration of the technique, there is a lack of research that evaluates the solution’s trade-offs. In this direction, this
work compares two solutions to mitigate the cold-start: Prebaking and SEUSS. We analyzed the solution’s performance with functions of different levels of complexity: NoOp, a function that renders Markdown to HTML, and a function that loads 41 MB of dependencies. Preliminary results indicated that Prebaking showed a 33% and 25% superior performance to startup the NoOp and Markdown functions, respectively. Further analysis also revealed that Prebaking’s warmup mechanism reduced the Markdown first request processing time by 69%.
