NEW QUESTION # 24
You have a Deployment running a database application with a stateful application using a StatefulSet. How can you scale the database to handle increased read traffic without impacting the write performance for the stateful application?

Answer:

Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Use a Read Replica:
- Create a read replica of the database that replicates data from the primary database.
- Use the read replica for read-only operations to distribute the read load.
2. Configure the StatefulSet:
- Configure the StatefulSet to access the read replica for read-only operations.
- Use a separate Service for the read replica and configure the StatefulSet to access it.
3. Implement a Load Balancer:
- Use a Load Balancer to direct read traffic to the read replica and write traffic to the primary database.
- Configure the Load Balancer to use a specific port for read requests and another port for write requests.
4. Monitor Performance:
- Monitor the performance of both the primary database and the read replica.
- Ensure that the read replica is adequately handling the read load without impacting the write performance on the primary database.
5. Scale Read Replicas:
- If necessary, scale the number of read replicas to handle increased read traffic.
- Add more read replicas as needed and adjust the Load Balancer configuration to distribute the traffic evenly.
