Abstract
The evolution of cloud computing has necessitated efficient deployment strategies for microservices, with container- ization emerging as a key solution. This paper explores the role of Docker in streamlining microservice deployment, focusing on the use of multi-stage builds, lightweight containerization, and cloud-based registries for scalable and efficient application man- agement. By leveraging Docker, microservices achieve enhanced portability, reduced resource overhead, and simplified depen- dency management. Furthermore, the paper discusses the lim- itations of standalone containerized applications and highlights the need for orchestration platforms like Kubernetes to ensure resilience, dynamic scaling, and automated service discovery. Through a practical implementation, this study demonstrates the benefits of containerized microservices and provides insights into optimizing cloud-native deployments.
