Description

Method, Device, and Program for Performing Service Migration Through Pod Replication in a Cloud Environment The present disclosure relates to service migration technology in a cloud environment, and more specifically, to a method, apparatus, and program for migrating services without interruption by replicating pods between multiple clusters. With the recent rapid advancement of cloud computing, container-based environments are establishing themselves as the standard technology for the deployment and management of various applications and services. Container technology enables applications to run in isolated environments through lightweight virtualization, and is being adopted by an increasing number of enterprises and service providers due to its characteristics that provide efficient resource management, rapid deployment, and portability. In particular, Pods, the units that run containers, play an essential role in cloud environments, enabling applications to operate consistently across various infrastructures. Container orchestration tools like Kubernetes systematically manage these Pods and provide automated deployment, scalability support, and resilience. Kubernetes can increase service availability and minimize downtime by moving or replicating Pods between multiple clusters as needed. However, there are several significant challenges in performing service migrations in existing cloud environments. Service interruptions or data consistency issues that may occur during cross-cluster migration can severely impact service quality and become critical problems, particularly for services requiring high availability. Traditional migration methods rely primarily on manual configuration and involve resetting clusters or suspending services during operation to move data. This process is complex and time-consuming, and can lead to issues such as degraded network performance and resource imbalances. These situations are highly likely to ultimately result in a decline in service quality. In particular, for stateful applications, it is difficult to maintain data consistency by simply cloning or moving pods or containers. This is because applications require real-time data processing or a tight connection with data repositories. Such applications are at high risk of data loss or consistency issues during migration, and special recovery procedures and sophisticated management mechanisms are required to prevent this.
