Chapter One — 1.1 Background to the Study

Organizations that depend on point of sale systems are under increasing pressure to modernize, and Microservices Architecture has emerged as one of the more promising avenues for doing so, given its demonstrated impact in related domains.

In practice, however, adoption of microservices architecture within point of sale systems has been uneven, and its actual impact on system performance is not yet well understood in a rigorous, evaluable way — a gap this study is positioned to address.

1.2 Statement of the Problem

Existing approaches to system performance within point of sale systems remain largely reactive and fragmented, with little systematic use of microservices architecture despite its demonstrated value elsewhere. This study addresses the resulting gap by designing and evaluating a solution built specifically around microservices architecture.

1.3 Objectives of the Study

1. To design and implement a microservices architecture-based approach to improving system performance in point of sale systems.
2. To evaluate the effectiveness of Microservices Architecture in enhancing system performance within point of sale systems.
3. To identify the key requirements and constraints relevant to deploying microservices architecture in this context.
4. To assess user and stakeholder perception of the resulting system.

1.4 Research Questions

1. How can microservices architecture be applied to improve system performance in point of sale systems?
2. How effective is Microservices Architecture at enhancing system performance within point of sale systems?
3. What requirements and constraints are relevant to deploying microservices architecture in this context?
4. How do users and stakeholders perceive the resulting system?

1.5 Significance of the Study

Beyond its immediate technical contribution, this study offers value to organizations evaluating whether to invest in microservices architecture for their own point of sale systems, and contributes to the broader literature on applied software technology / IT by documenting a concrete implementation and evaluation case.

1.6 Scope of the Study

As a BSc-level study, its scope is confined to designing and evaluating a microservices architecture-based solution for point of sale systems, focused specifically on system performance; broader deployment considerations fall outside this scope.
