General availability: Optional Uptime SLA for Azure Kubernetes Service private clusters
Published date: 21 January, 2021
We are releasing optional uptime SLA option for AKS private clusters in all AKS supported public regions. 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 higher availability of 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 SLA requirements are met.
