Architecture

Orchestration – Manage the Complexity

Durable Functions – Orchestrators for Azure Functions

Reduce Complexity Simplify

Enable Long Running FunctionsEnable

Orchestrate Functions Coordinate

Why do we need “Durable Functions”

Long Running & Local State

01Simplify Function Coordination

02Easy Function Communication

03Code-Only

04

What is Durable Functions?

Automatic Save of Local State

03No JSON schemas,

No designer!

01Sync & Async Functions Calls

02

F1 F2 F3 F4

// calls functions in sequencepublic static async Task<object> Run(DurableOrchestrationContext ctx){

try{

var x = await ctx.CallFunctionAsync("F1");var y = await ctx.CallFunctionAsync("F2", x);var z = await ctx.CallFunctionAsync("F3", y);return await ctx.CallFunctionAsync("F4", z);

}catch (Exception){

// global error handling/compensation goes here}

}

F2

F3

public static async Task Run(DurableOrchestrationContext ctx){

var parallelTasks = new List<Task<int>>();

// get a list of N work items to process in parallelobject[] workBatch = await ctx.CallFunctionAsync<object[]>("F1");for (int i = 0; i < workBatch.Length; i++){

Task<int> task = ctx.CallFunctionAsync<int>("F2", workBatch[i]);

parallelTasks.Add(task);}

await Task.WhenAll(parallelTasks);

// aggregate all N outputs and send result to F3int sum = parallelTasks.Sum(t => t.Result);await ctx.CallFunctionAsync("F3", sum);

}
