Azure Functions
Small pieces of code triggered by a timer, a queue or a request, billed only while they run.
Serverless compute
Chosen per project
Maintainable handover
Most business systems accumulate a set of jobs that have nothing to do with a user request: nightly syncs, reminder emails, reconciliation against a bank file, a webhook from a courier. Historically these ended up as scheduled tasks on somebody’s server, undocumented and invisible.
Functions give that work a proper home with triggers, retries, logging and its own deployment, while costing nothing on the days it does not run.
What we build with Azure Functions
Scheduled work — nightly imports, reminders, housekeeping
Queue processing behind a busy application
Webhooks from payment, logistics or messaging providers
Lightweight APIs with low or unpredictable traffic
Where it fits — and where it does not
Good fit when
Event-driven and scheduled work
Teams already on Azure with Entra identity
Integration glue between managed services
Consider something else when
Sustained heavy traffic, where App Service or containers cost less
Work that regularly exceeds the execution timeout
What sets a function off
Choosing the right trigger removes most of the code you would otherwise write.
Timer
Cron-style schedules for recurring work.
Queue
One message, one execution, with retries.
HTTP
Webhooks and small endpoints.
Blob or event
React to a file arriving or a resource changing.
How we work with Azure Functions
Triggers over polling
Queue, blob and event triggers instead of a loop that wakes up and checks.
Managed identity
Functions authenticate to storage and databases as themselves, with no connection secrets to leak.
Durable where needed
Multi-step workflows expressed with Durable Functions rather than chained timers.
Alerting on silence
A scheduled function that stops running is alerted on — the failure mode that otherwise goes unnoticed for weeks.
Our typical Azure Functions setup
| Concern | What we use |
|---|---|
| Runtimes | .NET isolated, Node.js, Python |
| Hosting | Consumption for spiky work, Premium where cold start matters |
| Identity | Managed identity to storage, SQL and Key Vault |
| Workflows | Durable Functions for orchestration and fan-out |
| Monitoring | Application Insights, with alerts on failures and on non-execution |
Frequently asked questions
That is one of the clearest wins. Scheduled tasks on a server are invisible, unlogged and tied to a machine; functions are versioned, logged and alerted on.
On the consumption plan, effectively nothing beyond the small storage account behind it. That is the main attraction for occasional work.
Durable Functions for multi-step sequences, or a single queue with one consumer where strict ordering is required.
