Chapter One — 1.1 Background to the Study

Microservices Architecture has become one of the more actively explored innovations in the design of modern mobile banking applications, promising gains in efficiency and reliability that legacy, largely manual approaches have struggled to deliver.

Despite this potential, many existing mobile banking applications were not originally designed with microservices architecture in mind, resulting in persistent gaps in threat detection accuracy that limit their overall effectiveness. This study examines how Microservices Architecture can be applied to help close that gap.

1.2 Statement of the Problem

Existing approaches to threat detection accuracy within mobile banking applications 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 threat detection accuracy in mobile banking applications.
2. To evaluate the effectiveness of Microservices Architecture in enhancing threat detection accuracy within mobile banking applications.
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 threat detection accuracy in mobile banking applications?
2. How effective is Microservices Architecture at enhancing threat detection accuracy within mobile banking applications?
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

This study is significant to software developers and system architects seeking practical guidance on applying Microservices Architecture within mobile banking applications. It is equally relevant to organizations that rely on these systems, offering a reference point for evaluating whether such an investment is justified, and it adds to the growing body of work on microservices architecture applications in software technology / IT.

1.6 Scope of the Study

The study is limited to the design, implementation, and evaluation of a microservices architecture-based approach to improving threat detection accuracy within mobile banking applications. Reflecting its clearly defined scope, it does not extend to a full commercial rollout or long-term post-implementation review beyond the study period.
