A user has developed an application which is required to send the data to a NoSQL database. The
user wants to decouple the data sending such that the application keeps processing and sending
data but does not wait for an acknowledgement of DB. Which of the below mentioned applications
helps in this scenario?

A.
AWS Simple Notification Service

B.
AWS Simple Workflow

C.
AWS Simple Queue Service

D.
AWS Simple Query Service

Explanation:
Amazon Simple Queue Service (SQS. is a fast, reliable, scalable, and fully managed message
queuing service. SQS provides a simple and cost-effective way to decouple the components of an
application. In this case, the user can use AWS SQS to send messages which are received from
an application and sent to DB. The application can continue processing data without waiting for
any acknowledgement from DB. The user can use SQS to transmit any volume of data without
losing messages or requiring other services to always be available.
