Abstract: Traditional monolithic CRM systems are increasingly challenged by demands for flexibility, scalability, and rapid digital transformation. This review explores how Linux containers and microservices enable the development of modular, scalable CRM platforms tailored to dynamic business needs. It begins with an analysis of architectural evolution from monoliths to microservices—and outlines the role of container technologies like Docker, Podman, and Kubernetes in modern CRM infrastructure. Core design principles such as domain-driven design, API gateways, service discovery, and CI/CD automation are examined to showcase how microservices enhance agility and maintainability. The paper also addresses persistent data handling, security best practices, and observability using tools like Prometheus, ELK, and Jaeger. Real-world case studies from finance, retail, healthcare, and telecom illustrate successful microservice-based CRM deployments. Challenges around complexity, skill gaps, and migration are acknowledged, along with mitigation strategies. Ultimately, the article demonstrates that containerized, microservices-driven CRMs offer a robust foundation for future-ready, adaptive customer engagement systems.
