Abstract

Several computing services are being migrated to cloud environments, where resources are available on demand and billing is based on usage. Databases in the cloud are increasingly popular, however their performance is a key indicator that must be known before deciding to migrate a system to a cloud environment. In this article, we present a preliminary investigation of the performance of database queries in Moodle, a popular Learning Management System, installed on cloud environments from Amazon Web Services and Google Cloud Platform. Experiments and performance analysis were based on benchmarks Pgbench, Sysbench and a Moodle Benchmark Plugin. We collected data and compare it with the results obtained on a local computer. In the configurations we tested, the results show that the Moodle database at Amazon’s provider performed better than Google’s. We made our data and scripts available to favour reproductibility, so to support decision makers on the migration of a Moodle instance to a cloud service provider.
