Azure Functions vs Grafana Cloud
The short version
- Each has a real cost: Azure Functions consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that; Grafana Cloud active Series (AS) billing model is difficult to predict and control; misconfiguration can cause sudden spikes and unexpected bills

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Azure Functions
- Consumption plan free grant is capped at 1 million executions and 400,000 GB-seconds of resource consumption per month per subscription, billed per GB-second beyond that
- The newer Flex Consumption plan's free grant is smaller still, at 250,000 executions and 100,000 GB-seconds per month
- Premium plan avoids per-execution charges but bills continuously for allocated core seconds and memory regardless of invocation volume
- Memory is rounded up to the nearest 128 MB and execution time to the nearest 1 ms for billing, so small overages round upward
Grafana Cloud
- Active Series (AS) billing model is difficult to predict and control; misconfiguration can cause sudden spikes and unexpected bills
- Reduced control and customization compared to self-hosted Grafana instances
- Data sovereignty concerns for organizations requiring on-premises data retention
- Limited reporting types compared to traditional BI tools for compliance and audit requirements
