Abstract

Using cloud computing allows to significantly improve the infrastructure support, reduce deployment time and faster adapt to changes in load with periodic peaks. The latter problem is solved by cloud application scaling that allows to change the number of involved computing resources depending on the cloud application use intensity. To solve the problem of selecting the best scaling strategy, a comparison mechanism of different scaling strategies with each other is needed. Such a comparison can be performed by calculating the developed efficiency criterion, which combines the assessment of used computing and reputational resources.

The developed criterion allows to calculate the cloud application efficiency based on information about the progress of a network request, the number of users and the cost of maintenance of cloud infrastructure. The criterion allows to compare and combine different metrics of cloud applications and can be used to compare the efficiency of cloud applications on the PaaS platform under different hosting settings using metrics that are specific to the PaaS platforms.

The paper shows that the efficiency of the brainstorming system Braintank combined with the information technology for cloud application scaling is by 10.5 % higher compared to other scaling technologies with a significance level of 0.001. Using the information technology for cloud application scaling has allowed to increase the values of the efficiency evaluation criterion from 8 to 12% on the simulator that reproduced the load on the World Cup website.
