General availability: Optional uptime SLA for Azure Kubernetes Service private clusters
Published date: 21 January, 2021
We are releasing an optional uptime SLA option for AKS private clusters in all AKS-supported public regions. The optional uptime SLA for AKS non-private clusters is already available. With this release, we are extending the same feature to private clusters to allow customers to choose a higher availability for the Kubernetes API server with secure private clusters.
Uptime SLA is an optional feature to enable a financially backed, higher SLA for a cluster. Uptime SLA guarantees 99.95% availability of the Kubernetes API server endpoint for clusters that use availability zones and 99.9% of availability for clusters that don’t use availability zones. AKS uses master node replicas across update and fault domains to ensure that SLA requirements are met.
