A Cost-efficient Multi-cloud Orchestrator for Benchmarking Containerized Web-applications.

Abstract

Benchmarking the containerized web-applications across multiple cloud gives web-application owners more chance to deploy their applications on cheaper host while meeting their performance requirements. However, benchmarking a large number of cloud hosts (about 267 cloud providers in the world) to find a flexible deployment option becomes a grand challenge. Users need to evaluate as many hosts as possible to find an option which offers expected performance at the lowest price. It is also necessary to benchmark the hosts for longer duration so that it can capture the uncertainty of cloud environment. In this paper, we present Smart Docker Benchmarking Orchestrator (SDBO), a general orchestrator that automatically benchmarks containerized web-applications in multi-cloud environment. At the same time, SDBO is able to maximize the numbers of evaluated cloud providers and type of hosts without exceeding users’ budgets. Moreover, we propose a flexible execution module which enhances SDBO ’s ability to capture the performance variation of benchmark web-application for longer period of time in the defined users’ budgets.
