How should a solutions architect redesign the architecture to better respond to changing traffic? What should the solutions architect do to separate the read requests from the write requests?
Understand the Problem
The question is asking how a solutions architect can redesign a web application's architecture to handle changing traffic effectively and examine performance metrics of a database on AWS. We will address issues related to traffic management and database performance separation.
Answer
C. Configure Auto Scaling with warmup; D. Create Aurora read replica.
For better response to changing traffic: C. Configure an Auto Scaling step scaling policy with an EC2 instance warmup condition. For separating read and write requests: D. Create a second Aurora database and link it to the primary database as a read replica.
Answer for screen readers
For better response to changing traffic: C. Configure an Auto Scaling step scaling policy with an EC2 instance warmup condition. For separating read and write requests: D. Create a second Aurora database and link it to the primary database as a read replica.
More Information
Using Auto Scaling with a warmup period helps manage sudden traffic spikes by allowing new EC2 instances time to become ready before serving requests. Creating a read replica helps distribute read requests, reducing load on the primary database and improving performance.
Tips
A common mistake is not setting a warmup condition in Auto Scaling, which can lead to inefficient scaling and response times.
