A Method for Comparative Performance Analysis of Communication Applications in Cloud and On-premise Environments

Abstract

Communication applications deployed in the cloud benefit from the various advanced features available in the environment. When deployed to an on-premise environment, the limited resources may cause performance issues that affect their functioning. If not resolved, these issues will hamper the performance of time-critical applications. The aim of this thesis is to analyze how performance issues arising from the migration of a communication application from a cloud environment to an on-premise environment can be identified and rectified. Analyzing the performance issues of the migrated application to the on-premise environment is essential as without understanding the root of the issue it might not be feasible to design a solution to resolve the same.

The thesis reviews multiple standards for performance analysis and frameworks for performance measurement. The currently available performance analysis solutions are also studied. The application is further reviewed to identify the priorities with regard to performance. Based on the gathered knowledge, a Performance Analysis method is defined. The defined method is then used over the application to identify performance issues.

From the acquired results, it can be concluded that the proposed method enables to identify factors to focus on, to obtain expected performance. The results were compared against established performance thresholds defined by the organization.
