KubeCon + CloudNativeCon + Open Source Summit + AI_dev China 2024

In the past year, Kuaishou successfully migrated nearly 100,000 Redis instances from traditional bare metal environments to the Kubernetes platform, achieving a significant doubling of resource utilization. While ensuring business stability, this large-scale migration faced numerous challenges, including smooth migration execution, finding a balance between increasing deployment density (resource utilization) and ensuring system stability, avoiding interference with other services during coexistence, and addressing specific issues associated with stateful services like databases (including data management, configuration management, ensuring high availability, cross-cluster disaster recovery, etc.). This session will share Kuaishou's large-scale practical experience in Redis cloud-native transformation, in collaboration with the open-source project KubeBlocks, covering aspects such as smooth migration, resource efficiency improvement, and efficient database management.

在过去的一年中，快手成功将近10万个Redis实例从传统裸机环境迁移到Kubernetes平台，实现资源利用率显著翻倍。在确保业务稳定性的同时，这一大规模迁移面临诸多挑战，包括顺利执行迁移、在增加部署密度（资源利用率）和确保系统稳定性之间找到平衡、在共存期间避免与其他服务的干扰，以及解决与数据库等有状态服务相关的特定问题（包括数据管理、配置管理、确保高可用性、跨集群灾难恢复等）。 本场演讲将分享快手在Redis云原生转型方面的大规模实践经验，与开源项目KubeBlocks合作，涵盖顺利迁移、资源效率提升和高效数据库管理等方面。
