Azure Functions Python Cookbook

Service Matrix

Service Combination Matrix¶

This reference maps Azure services to Azure Functions trigger and binding patterns, showing which cookbook recipes cover each combination. Use it to quickly locate an example or to identify coverage gaps.

Rows represent Azure services that integrate with Functions. Columns represent the 13 pattern categories in this cookbook. Each cell either links to a recipe or shows — where no recipe currently exists.

Integration Gaps¶

The following service-category combinations have no recipe today. These represent natural candidates for future additions.

Service	Missing categories	Notes
API Management	Blob, Msg, Stream, Data, Orch, Ops, RT, AI	APIM primarily fronts HTTP triggers; bindings to other services would be indirect
Front Door	Sched, Blob, Async, Msg, Stream, Data, Orch, Rely, Sec, Ops, RT, AI	Front Door routes to HTTP triggers only; no native binding
CDN	All	CDN offloads static assets; no native Functions trigger or binding exists
Key Vault	APIs, Sched, Blob, Async, Msg, Stream, Data, Orch, Rely, Ops, RT, AI	Key Vault is consumed via secret references and the SDK, not a dedicated binding
Azure Cache for Redis	APIs, Sched, Blob, Async, Msg, Stream, Data, Orch, Sec, Ops, RT, AI	No native Redis trigger/binding in the v2 Python model; SDK-only today
Cosmos DB	APIs, Sched, Blob, Async, Msg, Stream, Sec, Ops, RT, AI	HTTP + Cosmos DB (CRUD API), Timer + Cosmos DB (scheduled aggregation) are good candidates
Azure SQL	Sched, Blob, Async, Msg, Stream, Orch, Rely, Sec, Ops, RT, AI	SQL trigger (change tracking) support is preview; Sec recipe for Managed Identity SQL is a gap
Blob Storage	APIs, Sched, Async, Msg, Stream, Orch, Rely, Ops, RT, AI	HTTP + Blob (upload endpoint), Timer + Blob (cleanup job) are natural additions
Queue Storage	APIs, Sched, Blob, Stream, Data, Orch, Ops, RT, AI	Durable + Queue (external event) is a documentation gap
Service Bus	APIs, Sched, Blob, Async, Stream, Data, Sec (input), Ops, RT, AI	Service Bus input binding (peek) recipe is absent
Event Hub	APIs, Sched, Blob, Async, Msg, Orch, Rely, Sec, Ops, RT, AI	Event Hub output binding (producer) recipe is absent
Event Grid	Sched, Async, Stream, Data, Orch, Rely, Sec, Ops, RT, AI	Event Grid output binding (custom topic publish) is a gap
SignalR	APIs, Sched, Blob, Async, Msg, Stream, Data, Orch, Rely, Sec, Ops, AI	HTTP + SignalR negotiate endpoint recipe is absent
Azure OpenAI	Sched, Blob, Async, Msg, Stream, Data, Orch, Rely, Sec, Ops, RT	Timer-triggered batch inference and Service Bus + OpenAI worker are candidates
AI Search	APIs, Sched, Blob, Async, Msg, Stream, Data, Orch, Rely, Sec, Ops, RT	HTTP + AI Search (semantic search API) recipe is absent
