![]() When an endpoint scales out to multiple instances, each instance consumes messages from the same input queue. The transport initiates all network connections to SQS and S3 hence the endpoint itself does not need to be publicly accessible and can reside behind a firewall or proxy. Endpoints may access SQS queues whether they are deployed in AWS or not as long as the endpoint can reach both SQS and S3 via HTTPS it can use the transport. Queue ( " deadLetterQueue ", from queue`) Īwait Promise.The topology used by the transport is composed of several AWS components.Īmazon SQS exposes queue endpoints that are publicly available via HTTPS. Import * as aws from " " const deadLetterQueue = new aws. Run the command shown below to create a new Pulumi project with TypeScript in a default dev stacks in your preferred AWS Region (mine is US East 01). Ensure you've installed the CLI and have configured an IAM User with an Access Key in your AWS Profile. Initially, a new Pulumi project will be initialized using the Pulumi CLI. Therefore, this implementation will be using Pulumi. It directly deploys infrastructure using the typed language, rather than transpiling back to CloudFormation, which makes your deployments a bit faster. Pulumi is an IaC tool that enables developers to provision infrastructure using their favourable programming language. We will be using the IaC approach with Pulumi. There are several ways this infrastructure can be provisioned. The SQS Queue will push the failed messages to a DLQ if the Lambda processing a message fails a defined number of times.
