Avaliação de serviços serverless: um experimento piloto

Abstract

This exploratory study investigates two serverless cloud computing services to identify and compare their characteristics and maturity. Serverless emerge as the leading technology for implementing microservices. However, services Serverless have significant differences in relation to (i) characteristics, (ii) prices and (iii) maturity. Identifying these differences is important in the decision to adopt the service. First, the serverless services of the most relevant Function-as-Service (FaaS) category are identified today and then two, the Lambda Aws and the Azure Functions, were selected. Secondly, a study of the services was made and then some resources of the services chosen are compared. Afterwards, a pilot experiment was performed to identify the ease of use of the services from the perspective of the developer, without the objective of generalization of results, was carried out as the first attempt to validate a possible hypothesis that had the focus to identify if the effort (based on time) for creation and change of functions is the same or not, regardless of the platform chosen, for this was performed an experiment activity that had low adherence of participants. Finally the experimentation is analyzed and its results are restricted to a relationship between participants’ feedback regarding the use of the platforms, their knowledge obtained after the training and the justification of the time to perform experimental tasks.
