Professional managed Kubernetes clusters are developed on top of managed Kubernetes clusters. This type of cluster provides enterprise users with higher reliability and security in large-scale production environments and is covered by the service-level agreement (SLA) that supports compensation clauses.

Professional managed Kubernetes clusters inherit all benefits that are provided by managed Kubernetes clusters. For example, master nodes are highly available and managed by Container Service for Kubernetes (ACK). In addition, professional managed Kubernetes clusters provide higher reliability, security, and schedulability and are covered by SLA terms for compensation. Professional managed Kubernetes clusters are suitable for enterprises that require higher security and stability for large-scale workloads in production environments.


  • Internet enterprises. These enterprises deploy their business on a large scale and require business management with high stability, security, and observability.
  • Big data computing enterprises. These enterprises deploy large-scale data computing services, high-performance data processing services, and other services with high elasticity. These services require clusters with high stability, high performance, and efficient computing capabilities.
  • International enterprises that run their business in China. These enterprises prioritize security and services that provide SLAs with compensation clauses.
  • Financial enterprises. These enterprises require SLAs with compensation clauses.


  • Managed master nodes with higher reliability: The API server can automatically scale a cluster to a large number of nodes without service disruption. etcd is a reliable store for disaster recovery and data restoration. etcd uses cold backups and hot backups to ensure the availability of databases for professional managed Kubernetes clusters. Key metrics are collected for you to gain insights from control components. This allows you to predict potential risks in master node management.
  • Clusters with higher security: By default, etcd uses encrypted disks in the control plane. In the data plane, kms-plugin is installed to encrypt Kubernetes Secrets. ACK provides security management for this type of cluster. The advanced security management feature allows you to inspect containers in the running state and enable auto repairing.
  • More intelligent pod scheduling: kube-scheduler is integrated to provide better pod scheduling capability. This allows you to schedule pods in bulk, set multiple scheduling algorithms, and schedule pods to NPU-accelerated nodes. This also enhances the pod scheduling capability in scenarios where large-scale data computing or high-performance data processing is required.
  • SLA guarantees: Professional managed Kubernetes clusters are covered by the SLA that supports compensation clauses. A level of 99.95% uptime is guaranteed for the cluster API server.

The following table compares professional managed Kubernetes clusters with standard managed Kubernetes clusters.

Note Managed ACK clusters are renamed standard managed Kubernetes clusters.
