AWS Eventbridge with SQS Target via Terraform

Decoupling via Eventbridge

In this post we will setup a pretty common architecture pattern for async data processing on AWS. Distributed applications can fire events to Eventbridge and the payload gets forwarded to a SQS queue, dependent on defined rules.

To create the infrastructure we use Terraform(IaC) with the following module:

GitHub - terraform-aws-modules/terraform-aws-eventbridge: Terraform module which creates…

This module is able to create an event bus that accepts events and forwards them based on defined rules to connected targets. Let’s get our hands dirty and connect a new SQS queue to the default event bus of AWS Eventbridge:

resource "aws_sqs_queue" "queue" {
  name = "processing-queue"
  sqs_managed_sse_enabled = false
  visibility_timeout_seconds = 30 #30 seconds
  message_retention_seconds = 86400 #1day
}

module "eventbridge" {
  source  = "terraform-aws-modules/eventbridge/aws"
  version = "v1.17.1"
  create_bus = false #use default bus

  rules = {
    processing = {
      description   = "Capture all processing events"
      event_pattern = jsonencode({ "detail-type" : ["my/event"] })
      enabled       = true
    }
  }

  targets = {…
