Using TOGAF for Migration of Monolith Systems to Microservices

Abstract

Switching from monoliths to a microservices architecture is a significant turning point in today’s business world and helps to overcome issues in modern systems, including but not limited to scalability limitations, high rigidity, and system vulnerability. This research assesses how TOGAF’s ADM can help support this transition alongside employing Agile for step-by-step progress. Building on TOGAF’s phased approach, the research reveals systematic scalability by improving the system by 40% and decreasing downtime by 30% in a high-traffic period. Furthermore, using such a transition approach reduced business interruption by 25 % by employing hybrid migration strategies. Integrating through agile implies that changes can be done in cycles to enhance the framework's efficiency and minimize a program’s technical deficiencies. For example, implementing the containerization tool Kubernetes improved deployment and thus cut down the time to market by 20%. In addition, TOGAF’s governance framework manages risks effectively and has driven and aligned them with business objectives to maintain compliance standards, as discussed by a financial institution that achieved a 35% reduction of operation risks during migration. This paper also discusses the issue of organizational resistance and complications that come with distributed systems, and a recommendation is made whereby stakeholders' resistance is countered and feedback from users is considered to maintain strategic directions. The study's findings show real-case examples of how such modernization can be done while maintaining integrity and advantage for enterprises.
