* Go back and repeat the steps to create your database. It should work this time.
It will take some time for your database to be provisioned. While that's happening you can move on to the next steps in the lab.

We're going to install a handy web application in order to get some practice setting up our database. Nextcloud has all kinds of capabilities, the most obvious one is that you can use it to share files (of any size) with specific users or make them public for anyone to access.
 
The subnet-ops345-db RDS instance you created is called a database, which is confusing, because inside it you're going to make a database. subnet-ops345-db is actually more akin to an RDBMS (Relational Database Management System). Like installing MariaDB on a linux box. Inside the RDBMS you create what's more commonly called a database by more technical people. You can have many databased on one database server. But you cannot have any database inside another database - that just doesn't make sense.
 
There are graphical applications for managing databases, and sometimes they're quite helpful. But for you it wouldn't be worth learning their interface for the basic things you need to do for the lab. Also the command-line commands you will learn in this lab are good because they will work on almost any MySQL/MariaDB database server.
 
You'll need some extra software to be able to connect to subnet-ops345-db from
* Go back and try again to create the database.
* Assign temporary elastic IP to yum install mariadb, no need for server.
** Will disassociate and release the elastic ip at the end of the lab.
