  •  SQS

Lab description

You have been tasked with creating a prototype new Amazon SQS queue that satisfies the new requirements.

To complete this challenge, you will need to use the following Amazon Resource Names (ARNs):

  • An IAM role for producers to access queues exists.
  • An AWS Lambda function for processing messages exists.
  • An Amazon SQS queue exists for storing undeliverable messages.

Learning Objectives

  • Create and configure a FIFO Queue
  • Restrict access to queue to an existing producer
  • Create a trigger for a Lambda function

Prerequisites

  • AWS account

Lab steps

  1. Create an Amazon SQS Queue. Create an Amazon SQS queue that guarantees that each message will be delivered exactly once. So it’s a FIFO queue.
  2. Set a Window for SQS Queue Consumers to Process Messages. Configure your queue to hide a message from other consumers for twenty seconds after a message is received from a queue. Set the visibility timeout for 20 seconds.
  3. Delay the Delivery of New SQS Messages. Configure your queue to delay the delivery of new messages for five minutes. Delivery delay set to 5 minutes.
  4. Set the SQS Message Retention Period. Set the message retention period for your Amazon SQS queue to one day.
  5. Restrict SQS Queue Access to an IAM Role. Create and apply an IAM access policy for your Amazon SQS queue that allows all actions for the existing producer IAM role.

     "Id": "__default_policy_ID",
     "Statement": [
       {
         "Sid": "__owner_statement",
         "Effect": "Allow",
         "Principal": {
           "AWS": "arn:aws:iam::<<Your-account-number>>:role/<<Producer-name>>"
         },
         "Action": [
           "SQS:*"
         ],
         "Resource": "arn:aws:sqs:us-west-2:<<Your-account-number>>:MyQueue.fifi"
       }
     ]
    }
  6. Configure an SQS Dead Letter Queue. Configure your Amazon SQS queue to use the existing dead letter queue. Enable the option and choose a DLQ.
  7. Create an AWS Lambda Trigger. Configure your Amazon SQS queue to trigger the existing lambda when receiving messages. After creating the queue, go to Lambda triggers and choose a Lambda function to be triggered by the queue.
