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
Pulumi
- The free Individual plan allows one user and one concurrent stack update
- The Team plan is $40 per month base including 40 credits, and caps the organisation at 10 users
- SAML/SSO, RBAC, audit logs and drift detection require the Enterprise plan at $400 per month base
- The per-resource rate rises from $0.1825 per resource per month on Team to $0.365 on Enterprise, so upgrading raises the unit price as well as the base fee
- Managed secrets are billed separately at $0.50 per secret per month on Team and $0.75 on Enterprise
- Self-hosting, SCIM user sync, audit log export and 24x7 support are only in Business Critical, which is custom priced with no published rate
- Team includes up to 500 resources and Enterprise up to 2,000, with everything beyond billed on demand as credits
