Azure Functions — Serverless for .NET Enterprise

Our Azure clients have .NET developers, Visual Studio, and Azure DevOps. Azure Functions offer them serverless that fits into their ecosystem without friction.

Azure Functions vs. AWS Lambda¶

Runtime support: C# and F# as first-class citizens (not an afterthought like in Lambda). Durable Functions: stateful workflow orchestration in a serverless way — something Lambda Step Functions handle much more cumbersome. Trigger binding model: declarative connections to Azure services.

Durable Functions — Killer Feature¶

Orchestration patterns the serverless way: function chaining, fan-out/fan-in, human interaction, monitoring. A state machine without explicit state management.

Client Use Cases¶

• Bank: processing incoming SWIFT payments — event trigger from Service Bus
• Insurance: generating PDF documents — HTTP trigger, output to Blob Storage
• Retail: inventory sync between POS and e-shop — Timer trigger + Cosmos DB

Premium Plan for Enterprise¶

The Consumption plan has cold start. The Premium plan offers pre-warmed instances, VNET integration (access to on-premise resources via VPN), and unlimited execution time. A necessity for enterprise workloads.

Serverless in the Azure Ecosystem¶

Azure Functions with Durable Functions is a powerful combination for event-driven enterprise workloads. For .NET teams on Azure, it’s the natural choice.
