SQS
SQS stands for simple queue service. It is a queuing service for message processing, It is a system that polls the queue to discover new events.
Messages in the queue are typically processed by a single consumer. It is a fully managed queuing service for reliable communication between distributed software components and microservices at any scale.
It is used to decouple applications o they can run and fail independently, It also builds applications that are fault-tolerant and easy to scale. With the help of SQS, we can exchange messages between any number of systems at any volume without loss of messages.
It gives us a new queue that is reliable and scalable which is first in first out which is typically called as FIFO.
