All You Wanted to Know About Amazon SQS in 10 Minutes

No one can ignore Amazon AWS while discussing cloud-based server infrastructure. If you’re looking for a simple way to learn the fundamentals of Amazon Simple Queue Service (SQS) and determine whether or not it’s a good fit for your needs, you’ve come to the right spot. In this article, we’ll answer some of the most often-asked questions regarding this system and the integrations it provides, as well as go through its essential features and use cases.

What exactly is the function of Amazon Simple Queue Service?

Manage asynchronous communication between applications or microservices with Amazon’s Simple Queue Service (SQS), a message queuing service.

If you’re unfamiliar with queueing, try thinking of it as a conversation between two people who have subscribed to the same mobile network. At all times, there must be at least two parties involved: the sender (producer) and the receiver (consumer) (the one who receives it). Both people must be accessible online to have a direct conversation (a phone call, for example).

The asynchronous conversation is very much like platform messaging or even SMS. In this scenario, the producer sends a message to an intermediate server where it will “wait” until the consumer becomes accessible. A message is sent and received as soon as the recipient is accessible, and the recipient then acts upon the information (reads, forwards to another subscriber, etc.)

There are two methods for handling messages in Amazon SQS.

Conventional lines. This is the default kind and guarantees the delivery of messages at least once. The app you’re developing must process messages that arrive several times and out of sequence.

The first-in, first-out line system. The FIFO (first-in, first-out) approach processes messages just once and in a predetermined order.
In contrast to the discussion, Queued messages must be discarded after being processed to prevent duplication.

This is a highly simplified explanation of how SQS handles message queueing. If you’re interested in learning more, the official documentation for Amazon SQS provides a brief overview of the system’s fundamental design.

Before beginning work with Amazon SQS, it is vital to familiarise yourself with the following key concepts:

Timeout for Amazon SQS visibility. During this time, no other users will be able to receive or handle the message. It has a range of 0 minutes and 12 hours that you may set.

Dead-End Lineups. You’ll find them in messages that failed to be processed. You merely need to set the criteria for when the failed message should be transferred to a dead-letter queue. The maximum received count, or the number of times a message was sent but never delivered, can be set by interconnecting the source queue with a dead-letter queue.

When the maximum number of messages in the source queue is reached, the messages are redirected to the dead-letter queue, and the source queue is emptied. You may also set up alerts for bounced messages, allowing you to quickly review those that ended up in dead-letter queues and figure out what went wrong. Use dead-letter queues to investigate the reasons behind message failure by reviewing the content of failed messages and the exceptions that led to their delivery.

Using Amazon Simple Queue Service In-Depth and Quick Surveys Both involve taking in some form of communication. When the time spent waiting for the ReceiveMessage API action is more than 0, this is known as long polling. Short polling occurs when the waiting time is equal to zero.

By default, we utilize a quick polling method. You may need to send several consecutive requests to retrieve all server messages. Still, you will get a faster response time since it only asks a subset of Amazon SQS servers (where the queue stores and processes messages). Amazon SQS polls all of its servers for messages until it times out. A request in this scenario takes longer to complete, but it has a better probability of not returning an empty result set.

What is the price tag for Amazon SQS?

SQS follows the same “pay for what you use” pricing approach as the rest of Amazon’s services. In reality, you’ll have to shell out cash for each request (1 request = 64 KB of payload). No fees are ever charged for the first million monthly inquiries. Using regular queues will cost you $0.4 per million requests, whereas FIFO will set you back $0.5 per million.

Remember that the entire payload for a single API request may be no more than 256 KB and that there can be anywhere from 1 to 10 individual messages (4 chunks of 64 KB). You should also keep in mind that fees will be associated with any data sent forth.

Estimating the monthly requests for each queue type and the data transfer volume might help determine how much Amazon Simple Storage Service will cost.

Your message will be available for processing by other programs once you’ve sent it to a queue. To link your app to the queue in this Amazon service, you must provide the queue’s uniform resource locator (URL) (which you will find in the queue Details tab).

Messages may be requested to be seen (by selecting Start Polling for messages) and then deleted from the Queue Actions menu.

You can subscribe to a queue to an SNS topic and set up a trigger based on a Lambda function from the Queue Actions menu.
