Controlling the elasticity of web applications on cloud computing
Michel Albonico, Jean‐Marie Mottu, Gerson Sunyé · 2016
Web applications are often exposed to unpredictable workloads. Therefore, they must ensure elasticity, which is addressed by hosting these applications on cloud computing infrastructures. In presence of elasticity, the application and its service layers may run adaptation tasks, which assist them in behaving in an elastic manner. These tasks may introduce errors. Therefore, the application must be tested when the adaptation tasks run. Some adaptation tasks may run only during specific elasticity behavior, and it is difficult to achieve specific behaviors without controllability. Therefore, in this paper, we propose an approach that controls the elasticity of Web applications according to requirements. It is the first step towards an approach to test elasticity applications through elasticity.
