3. Wait for the PolarDB Instance to be Ready and Enjoy Exploring
After the instance changes to Running, you can use it. You may need the set up a network (whitelist and endpoint) and authentications (database user and password) before logging into the instance. Please use the following Quick Start for reference:
Considering the configurations (such as Storage Type and Hot Standby Cluster of free trial instance) may not fully meet your business needs, we recommend launching new instances after testing (when you decide to implement PolarDB for production).
If you want to extend the duration of the instance after evaluation, you can continue with Renew to convert the free trial to a paid plan.
Also, you can upgrade specifications from the beginning and then renew the instance.
You will not be charged after the free setup expires, but we recommend releasing the resource if you don't have plans to convert to a paid plan after achieving the goal of learning or testing.
Let's see how to release a PolarDB instance. It only requires two simple steps.
First, change the billing method of the instance to pay-as-you-go.
Click Release when the billing method is successfully changed. In order to avoid unnecessary fees, we recommend choosing Immediately Delete All Backups if the test data stored on the instance is not expected to be used again (especially for production). Otherwise, you might be charged storage fees generated by backup retention.
