SQS,SNS, Kinesis, Firehose and etc.

Question 1

SQS - You are getting large bills for the worker pool - `ReceiveMessageWaitTimeSeconds

Answer 1

Configure requests to the SQS Queue with “ReceiveMessageWaitTimeSeconds” with a higher value

Question 2

A leading media company plans to launch a data analytics application. The SysOps Administrator designed an architecture to use On-Demand EC2 instances in an Auto Scaling group that read messages from an SQS queue. A month after, the new application has been deployed to production but the Operations team noticed that when the incoming message traffic increases, the EC2 instances fall behind and it takes too long to process the messages.

How can the SysOps Administrator configure the current cloud architecture to reduce the latency during traffic spikes?

Answer 2

Configure the Auto Scaling group to scale out based on the number of messages in the SQS queue

You can configure the scale-out policy to check the number of messages in your SQS queue and then verify that your Auto Scaling group has launched an additional EC2 instance

Question 3

A startup hosted a photo editing application on a large On-Demand EC2 instance. The application allows users to add effects and filters to their photos which are then stored as a media file in an S3 bucket.

Which of the following services will help them build a scalable and decoupled architecture in AWS for this application?

Answer 3

Amazon Simple Queue Service (SQS)

NOT AWS STS is incorrect because STS is a web service that is used for requesting temporary tokens to authenticate users.
