NServiceBus.AwsLambda.SQS - Public preview release available

Hi everyone,

We’ve just released a public preview version of NServiceBus.AwsLambda.SQS.

With NServiceBus.AwsLambda.SQS you can deploy your message handlers to AWS as Lambda functions. The powerful NServiceBus programming model, combined with AWS Lambda, makes it a breeze to build easy-to-deploy, scalable, pay-as-you-go distributed systems.

NServiceBus.AwsLambda.SQS allows AWS Lambda to do the heavy lifting of deployment and runtime management, while benefiting from all the usual NServiceBus features:

  • Full compatibility with NServiceBus endpoints
  • Immediate and delayed retries
  • Stateful message processing with NServiceBus Sagas
  • Auditing
  • Dependency injection support
  • Advanced pipeline extensibility
  • and more…

Getting Started

NServiceBus.AwsLambda.SQS makes endpoint configuration super simple:

static readonly AwsLambdaSQSEndpoint endpoint = new AwsLambdaSQSEndpoint(context =>
{
    var endpointConfiguration = new AwsLambdaSQSEndpointConfiguration("AwsLambdaSQSTrigger");
    
    //customize configuration here

    return endpointConfiguration;
});


public async Task FunctionHandler(SQSEvent evnt, ILambdaContext context)
{
    var cancellationDelay = context.RemainingTime.Subtract(TimeSpan.FromSeconds(10));
    using (var cancellationTokenSource = new CancellationTokenSource(cancellationDelay))
    {
        await endpoint.Process(evnt, context, cancellationTokenSource.Token);
    }
}

With the configuration done, just add message handlers for any message type received by the function:

public class TriggerMessageHandler : IHandleMessages<TriggerMessage>
{
    static readonly ILog Log = LogManager.GetLogger<TriggerMessageHandler>();

    public Task Handle(TriggerMessage message, IMessageHandlerContext context)
    {
        Log.Info($"Handling {nameof(TriggerMessage)} in {nameof(TriggerMessageHandler)}");
        return context.SendLocal(new FollowupMessage());
    }
}
