Balancing Service Risk with Technology Cost for Web-based Applications using Emulation Driven Simulation

摘要

Organizations that operate in the e-commerce domain typically have hundreds of web-based applications that have to be updated when new software or stacks are launched. This requires extensive testing to maintain quality of service, while minimizing downtime. In this research, we propose a structured method for classifying applications and testing new stacks for each type of application thoroughly before deploying all applications on the new stack. The method uses an emulation-simulation approach and would contribute to the organization's leadership in providing high quality service to its customers while eliminating unnecessary expenditure on excess testing and maintaining multiple stacks, resulting in significant cost savings.
