AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A company's application is experiencing performance degradation due to increased read traffic on its primary database hosted in the North Virginia region. The user base is distributed across North America and Europe. The company wishes to optimize read performance for these users. Which approach should be adopted to enhance the application's read traffic handling capacity while also addressing the geographical distribution of the user base?
Upscale the compute and memory resources of the current primary database to handle the increased traffic.
Establish replicas in regions that are geographically closer to users in North America and Europe to handle read traffic efficiently.
Transition to a higher provisioned IOPS configuration for the current database deployment.
Launch an additional database in the same region as the primary without enabling replication features.
Creating replicas of your primary database in regions closer to your user base can significantly decrease read latency and serve read requests more efficiently due to the geographical closeness. It also offloads the read traffic from the primary database, resulting in better overall performance for the workload. This approach leverages AWS's global infrastructure to provide low latency access to users spread across different geographical locations, as opposed to just resizing the primary database or adding more provisioned IOPS, which would not address the issue of geographically diverse user latency. Deploying a separate database in the same region does not aid in distributing load or improving access times for users located elsewhere.
