Monthly outbound data (GB)

Calculating…

Control plane upgrade

Free → Standard is £55.10/month per cluster hidden fee. Across 5 environments: £275/month before a single node.

Uptime SLA is an add-on

Uptime SLA does not replace the Standard tier fee — it adds to it. Standard + Uptime SLA = £110.20/month per cluster.

Spot node interruption

Azure can evict Spot nodes with 30 seconds notice. Avoid Spot for stateful workloads or anything requiring guaranteed availability.

Hidden Load Balancer egress

AKS provisions a Standard LB by default. Outbound rule data processing charges (£0.0037/GB) do not appear on the AKS pricing page.
