 AMAZON Simple Queue Service (SQS)

Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications.

SQS eliminates the complexity and overhead associated with managing and operating message oriented middleware, and empowers developers to focus on differentiating work.

Using SQS, you can send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be available.

SQS offers two types of message queues. Standard queues offer maximum throughput, best-effort ordering, and at-least-once delivery. SQS FIFO queues are designed to guarantee that messages are processed exactly once, in the exact order that they are sent.

Case Studies

Now that you know a bit about the AWS SQS, let us look at some of the case studies.

BMW

The BMW Group is using AWS for its connected car application that collects sensor data from BMW 7 Series cars to give drivers dynamically updated map information. BMW built its new car-as-a-sensor (CARASSO) service in only six months leveraging Amazon SQS, Amazon S3, Amazon DynamoDB, Amazon RDS, and AWS Elastic Beanstalk.

Change Healthcare

Change Healthcare uses AWS services like Amazon EC2, Amazon S3, Amazon SQS, and Amazon SNS to handle millions of confidential transactions daily from its clients while maintaining with full compliance with healthcare industry regulations, including HIPAA.

redBus

redBus is expanding their AWS solution to include Amazon SQS and SNS for monitoring, alerts, and intercommunication. “Amazon SQS is an especially good solution for enabling messaging between external applications and our applications.” — Charan Padmaraju, redBus CTO

Oyster.com

Oyster.com uses Amazon Web Services to store and process images for their website. The team uses Amazon EC2 and Amazon SQS in an integrated workflow to generate the sizes they need for each photo. SQS communicates the photos that need to be processed and the status of the jobs.

Benefits

AWS manages all ongoing operations and underlying infrastructure needed to provide a highly available and scalable message queuing service. With SQS, there is no upfront cost, no need to acquire, install, and configure messaging software, and no time-consuming build-out and maintenance of supporting infrastructure. SQS queues are dynamically created and scale automatically so you can build and grow applications quickly and efficiently.

Use Amazon SQS to transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be available. SQS lets you decouple application components so that they run and fail independently, increasing the overall fault tolerance of the system. Multiple copies of every message are stored redundantly across multiple availability zones so that they are available whenever needed.

You can use Amazon SQS to exchange sensitive data between applications using server-side encryption (SSE) to encrypt each message body. Amazon SQS SSE integration with AWS Key Management Service (KMS) allows you to centrally manage the keys that protect SQS messages along with keys that protect your other AWS resources. AWS KMS logs every use of your encryption keys to AWS CloudTrail to help meet your regulatory and compliance needs.

Amazon SQS leverages the AWS cloud to dynamically scale based on demand. SQS scales elastically with your application so you don’t have to worry about capacity planning and pre-provisioning. There is no limit to the number of messages per queue, and standard queues provide nearly unlimited throughput. Costs are based on usage which provides significant cost saving versus the “always-on” model of self-managed messaging middleware.

  Installing Python3:   $ yum install python3 -y Installing the boto3 library:  $ pip3 install boto Creating a inventory directory: $ mkdir -p /opt/ansible/inventory $ cd /opt/ansible/inventory Creating a file aws_ec2.yaml in the inventory directory with the following configuration: plugin: aws_ec2 aws_access_key: <YOUR-AWS-ACCESS-KEY-HERE> aws_secret_key: <YOUR-AWS-SECRET-KEY-HERE> keyed_groups: - key: tags prefix: tag Open /etc/ansible/ansible.cfg and find the [inventory] section and add the following line to enable the ec2 plugin: [inventory] enable_plugins = aws_ec2 Now let’s test the dynamic inventory configuration by listing the EC2 instances: $ ansible-inventory -i /opt/ansible/inventory/aws_ec2.yaml --list The above command returns the list of EC2 instances with all its parameters in JSON format. Now, check if Ansible is able to ping all the machines returned by the dynamic inventory:  ansible all -m ping Dynamic inventory setup done. Launch...
