INTRODUCTION

Complex programs are created by modern developers, and these apps need a communication arrangement so that the components may exchange messages. Additionally, in some circumstances, even a slight shift in the message order can make the program worthless. Developers are looking for automated systems to help them manage this message-based collaboration by sharing the workload. Amazon SQS is one such message-management platform.

SQS frees developers to concentrate on producing work that stands out from the competition by removing the complexity and overhead associated with maintaining and operating message-oriented middleware. Additionally, even without message loss or the need for other services to be accessible, you can send, save, and receive messages across software components using this service at any volume.

What is Amazon SQS?

A fully managed service called Amazon SQS (Simple Queue Service) is well known for its message queuing capabilities. This service is frequently used by developers to send and receive asynchronous messages of different kinds and sizes. You can keep several distributed systems and microservices independent of one another thanks to Amazon SQS. Additionally, it automates the creation and maintenance of the message queues and enables scaling of these systems.

It is a blessing in disguise for developers because :

• A secure channel for enabling connections between software components is provided by Amazon SQS. 

• Amazon SQS offers a programming interface that enables you to use different web services by accessing them through well-known programming languages. 
• The services offered by Amazon SQS can be used by asynchronous processes. The fact that applications can now submit messages to a queue instead of attempting to directly launch another programme one at a time shows that Amazon SQS makes it simpler for them to complete their tasks.

• In this manner, that message can be simply viewed by numerous apps, and your software will operate with less time complexity.

In SQS, there are two different kinds of message queues.

The first is the standard queue. This offers best-effort ordering, maximum throughput, and at minimum one delivery.

• Standard queues are available as the default queue type in SQS.
• You can perform as many transactions per second as you like.
• It ensures at least one delivery of a message. A message may, however, occasionally be delivered in more than one form or out of order.

Although it does not offer a guarantee, best-effort ordering assures that messages are typically transmitted in the exact order they are sent.

Furthermore, SQS FIFO queues. Messages are guaranteed to be analyzed exactly properly and in the order, they are sent thanks to this.

• The standard Queue is supplemented by the FIFO Queue.
• It ensures that they are acquired in the same sequence in which they were sent, which is known as order.
• A message is delivered only once and is available until the consumer processes and deletes it. This is known as FIFO Queue and exactly-once processing.
• Duplicates are not permitted to be added to a FIFO queue.
• Additionally, it enables message groups, enabling the existence of many ordered message groups in a single Queue.
• FIFO Queues offer all the features of regular queues but are restricted to 300 transactions per second.

Characteristics of AWS SQS

 AWS SQS is a well-liked message management option among developers because of the features listed below:

• Durability: To keep your communications secure, Amazon SQS uses many servers. Additionally, the system's Standard Queues and FIFO Queues employ an at-least-once & entirely accurate message delivery scheme.
•  Availability: To produce high-speed concurrent communications, Amazon SQS makes use of redundant infrastructure. By doing this, it makes sure that there are more messages available for both consumption and production.
•  Scalability: Due to its ability to handle each request for a buffered message independently, Amazon SQS provides you with tremendous scalability. Additionally, it does not require any prior instructions and may scale transparently during unexpected traffic spikes.
• Reliability: During the processing stage, Amazon SQS employs a message locking mechanism. This enables several producers to communicate with several consumers at once

How has Amazon SQS helped us?

I will show you how to asynchronously group information from SQS and store it in an extremely informational database. Such a structure can be useful in a variety of circumstances, such as grouping and storing sophisticated information in a very broad range of applications, such as streaming platforms and e-commerce websites.

Processing data can be tedious, especially on computing units where read and write operations consume a lot of power. Fortunately, you can easily succeed if you have the right tools. SQS offers a lot of options and chances and might be a useful service.

A very effective method for separating message producers from message consumers is Amazon SQS. This is one method of configuring for reliability and scalability. You can have servers read messages from SQS and carry out the tasks listed in the messages in the background. If one of the servers goes down, another one will take over and finish the task. You can have confidence that the work will be completed eventually since SQS ensures that a message will be delivered eventually.

Through this system, Lucent Innovation has been successfully processing lakhs of requests on a daily basis. 

Our data can be encrypted with the assistance of Amazon server-side encrypted data (SSE), and it can then be shared between applications. A user can centrally manage the keys responsible for safeguarding SQS messages and other AWS resources due to the combination of Amazon SSE with AWS KMS (Key management service).

Benefits of SQS.

Secure sensitive data.

Our data can be encrypted with the support of Amazon server-side encryption (SSE), and it can then be shared between applications. A user can centrally manage the keys responsible for safeguarding SQS messages and other AWS resources due to the combination of Amazon SSE with AWS KMS (Key management service).

Scale elastically while remaining economical.

Because Amazon SQS scales flexibly based on demand, you do not need to worry about pre-provisioning or planning the capacity in advance. Each queue can hold an indefinite number of messages, and usage-based pricing applies. So, we may conclude that it provides a cost-effective and flexible service.

Reduce administrative costs.

According to demand, SQS queues can be automatically established and scaled. SQS eliminates the requirement for users to install messaging software in order to perform activities and manage the infrastructure.

Deliver messages consistently.

The application components are separated using Amazon SQS, increasing the system's overall fault tolerance while enabling each component to operate or fail individually. All of the messages' copies are kept in several zones and are accessible whenever necessary.

Conclusion

Amazon SQS is excellent for handling your messages and giving the right information to your programme at the right time.
