Sara’s paper “A Framework for Satisfying the Performance Requirements of Containerized Software Systems Through Multi-Versioning” was accepted for publication in the International Conference on Performance Engineering (ICPE)! Super congrats Sara! This was a joint work with Alireza Goli (UAlberta) and Hamzeh Khazaei (York University).
With the increasing popularity and complexity of containerized software systems, satisfying the performance requirements of these systems becomes more challenging as well. While a common remedy to this problem is to increase the allocated amount of resources by scaling up or out, this remedy is not necessarily cost-effective and therefore often problematic for smaller companies. In this paper, we study an alternative, more cost-effective approach for satisfying the performance requirements of containerized software systems. In particular, we investigate how we can satisfy such requirements by applying software multi-versioning to the system’s resource-heavy containers. We present DockerMV, an open source extension of the Docker framework, to support multi-versioning of containerized software systems. We demonstrate the efficacy of multi-versioning for satisfying the performance requirements of containerized software systems through experiments on the TeaStore, a microservice reference test application, and Znn, a containerized news portal. Our DockerMV extension can be used by software developers to introduce multi-versioning in their own containerized software systems, thereby better allowing them to meet the performance requirements of their systems.
