Endpoint and Auto Scaling

Endpoint is the entry point of Aurora that allow user to access DB. Normally It will separate between Writer endpoint and Reader endpoint for writing and reading procss to balance traffic.

Auto Scaling

For Auto scaling feature in case that we increase the number of read replica, it will aumatically add replica to reader endpoint.

Custom Endpoint

Moreover we can create our own custom endpoint to define a subset of Aurora instance but when we created it the reader endpoint will not be use.
