Today I studied about Databases on AWS, this topic was awesome for me although you should know about VCP, Networking and security and If you read the older post It's not my strength.
AWS has 2 types of databases available, SQL or relational DB (RDS), and NoSql Non-relational DB (DynamoDB).
RDS is a SQL Database that provides huge options for different engines. Here you will see Amazon Aurora, Mysql, Postgres, Oracle and Microsoft SQL server.
DynamoDB is a NoSQL Database service. Nowadays AWS doesn't have another NoSql option in its catalogue. One way that you can accomplish that is that you create an EC2 instance and install it MongoDB or Oracle NoSql.
Today I was practising a lot creating DB basically to understand much better VPC and Security. Here you can check the official tutorial about How to create an RDS.
That's all for today, I'm sorry for this short post but that was planned for today.
