Professional ACK Serverless clusters are developed based on ACK Serverless Basic clustersd provide higher reliability and security in large-scale production environments for enterprise users. ACK Serverless Pro clusters are also covered by service level agreements (SLAs) that include compensation clauses.
Overview
ACK Serverless Pro clusters are developed based on ACK Serverless Basic clustershis type of cluster inherits all benefits of ACK Serverless Basic clusters such as compatibility with the open source version, automated O&M, and scaling within seconds. In addition, ACK Serverless Pro clusters provide higher reliability and security, and are covered by SLA terms for compensation. ACK Serverless Pro clusters are suitable for enterprises that require higher security and stability for large-scale workloads in production environments.
Scenarios
Internet enterprises. These enterprises deploy their business in large-scale production environments 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 that include compensation clauses.
Features
Managed master nodes with high reliability: The management of large-scale clusters is supported. etcd is a reliable store for disaster recovery and data restoration. etcd uses cold backups and hot backups to ensure data availability for ACK Serverless Pro clusters. Key metrics are collected for you to gain insights from control components. This allows you to detect potential risks.
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. Container Service for Kubernetes (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.
SLA guarantees: ACK Serverless Pro clusters are covered by the SLA that supports compensation clauses. A level of 99.95% uptime is guaranteed for the cluster API server.
