Amazon Aurora is also a Database like MySQL but it comes with only 2 versions
Aurora (MySQL Compatible Edition)
Aurora (PostgreSQL Compatible Edition)
In a normal RDS Database, we will get only 5 Read Replicas but with Aurora, we will get 15 Read Replicas. Aurora is a global database and it is only available in RDS.
Writer- I was able to read and write the database
Reader - I was only to read I don't have any permission to create or write
MySQL WorkBench supports majorly MySQL type database but if you have another database engine such as MariaDB, Oracle and others so it shows some error while connecting.
Creating Aurora (MySQL Compatible)
We are going with MySQL edition because MySQL is already installed in our Instance.
Select Standard create
In Aurora, FREE Tier is not available so I am going with Production
In Settings, I gave the name to DB Cluster Identifier
Then I created a password for the Database
In Instance configuration, I selected the Burstable class because I don't much configuration requirements
I am going with the first option because I want Read Replica
This should be by default
I selected the Public Access
I unselected the Monitoring as per my needs
In Additional Configuration, I gave the name to my Initial database name
Rest things are default
The database got created, in which one is the Writer Instance and the second is the Reader Instance
We will able to create more Readers in the same region and across the region
Connecting with MySQL WorkBench
Click here to get connect with Database
In RDS, copy the endpoint of the Writer Instance
Connect with Writer Endpoint
In MySQLWorkBench, paste the Endpoint and enter the admin as the username
Then It will ask you to enter the password which you created in the RDS
After entering the password you will be connected
Once you connected this dashboard will be showing
I wrote a query, type the query pressed enter and select the text then click on the symbol
Result
I created a new database by the name of mydb
Now I used the same command to check available databases
Connect with Reader Endpoint
Copy the Endpoint of the Reader
In WorkBench
Setup the connection
It will ask you for the password
Connected now
It is showing now
Now If I try to create a database then it shows me an error, with Reader we cannot create the database.
Creating another Reader Replica
Select the Database and there is an option to create Reader
Follow the basic steps
Make it Publically Accessible
Rest Default and clicked Create and now It got created
Delete the Aurora Database
People get confused in deleting to delete this first we need to the Reader and as well as the Writer then after we will able to delete it.
We need to delete one by one
And if we see this type of message we need to disable the deletion protections first because it auto-selected comes in the Aurora
To Disable this select the Database and click to modify
Go down then unselect the deletion protection
After performing the above actions then we need to select the
It will take a few minutes to get completely modified and I deleted all the Reader and Writer so this will delete automatically.
Final result
The last thing Aurora creates automatically snapshot which is a back up
