Best use cases for Azure Functions
- Azure-first teams building event-driven functions
- Enterprise orgs with Microsoft governance and identity requirements
- Workloads that benefit from managed triggers and Azure service integrations
- Teams that want serverless without building an orchestration platform
Who should avoid Azure Functions?
- Edge latency is the primary value and global distribution is required
- You need minimal cloud coupling and maximum portability
- Your workload is sustained/heavy and better suited to always-on compute
Upgrade triggers for Azure Functions
- Cold start and tail latency become visible to users or APIs
- Concurrency/throughput assumptions break under peak traffic
- Need stronger governance/observability standardization across teams
