Heuristic for license-aware, performant and energy efficient deployment of multiple software in Cloud architecture

摘要

In the Cloud Era, we want to be able to quickly deploy any software anywhere in the world to provide high availability and fast services while maintaining acceptable levels of performance, low energy consumption and ensuring the compliance with every software level agreements contracted. To answer some of these needs, different tools exist in parallel to a big variety of Cloud architectures. Several interesting problems arise like deployment, networking, storage, security, and many others. In this paper, we will focus on the deployment issue with a Software Asset Management point of view. Most Cloud providers use proprietary software to ensure different kinds of services, and with them comes the licensing problem. We will tackle and propose a heuristic to solve the problem of deploying software in a Cloud architecture while considering license compliance, license price, and other important criteria. We will prove the NP-completeness of this problem and compare our heuristic with others to evaluate the enhancement we propose.
