Best use cases for Azure Functions
- Microsoft-ecosystem organizations where Azure Functions integrates naturally with Azure Service Bus, Event Hubs, Blob Storage, Cosmos DB, and Azure AD authentication — using existing Azure infrastructure without cross-cloud networking.
- Teams building .NET or C# backends where Azure Functions' native .NET support and Visual Studio integration provide a first-class development experience that Node.js-first serverless platforms can't match.
- Enterprises using Azure Logic Apps for orchestration where Durable Functions provides code-first workflow orchestration as a natural extension of the Azure integration ecosystem.
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
