AWS Aurora PostgreSQL Auto Scaling | All About

Did you know that Aurora PostgreSQL auto-scaling refers to Amazon Aurora’s capability to automatically adjust its capacity according to workload demands?

This ensures optimal performance as well as resource utilization.

If you are looking for a guide to help you set up Amazon Aurora PostgreSQL Auto Scaling, our experts have your back:

1. First, we have to create an Amazon Aurora PostgreSQL cluster with the AWS Management Console. Alternatively, we can use the AWS CLI. Remember to choose the correct instance type and storage capacity for our workload.
2. Then, set up read replicas within our Aurora cluster, set up read replicas. These replicas will handle read traffic and help with scaling our database. We can configure the number of read replicas and their placement.
3. Now, we have to enable auto-scaling for our Aurora cluster. This includes mentioning the target metrics for auto-scaling like CPU utilization, etc.
4. Next, it is time to set up auto-scaling policies that indicate how Aurora will respond when the defined metrics cross fixed limits.
5. After that, we have to set scaling actions that have to be taken when a scaling policy is triggered.
6. Once we set up auto-scaling, we have to closely monitor the performance of our Aurora cluster. Furthermore, we have to check if the auto-scaling policies are working.

How does Amazon Aurora PostgreSQL Auto Scaling work

• AWS constantly monitors the Aurora cluster’s metrics like CPU utilization, memory usage, etc.
• Furthermore, when a metric crosses a defined threshold, AWS triggers the corresponding auto-scaling policy.
• AWS performs the scaling action we defined when a policy is triggered.
• AWS dynamically creates or removes read replicas as needed to handle the workload.
• Aurora ensures data consistency across read replicas with its storage architecture.
• Furthermore, if a read replica fails, AWS will automatically replace it with a new one, helping to minimize downtime.
