Q

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?

A

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
