What is Amazon RDS?
Amazon RDS is a Relational Database Service by Amazon Web Services. A relational database is a type of database that stores data in tables with rows and columns. Amazon RDS provides an industry-standard relational database that is cost-efficient with resizable capacity. It gives users solutions for easier setup, operation, and scale of a relational database in the cloud.

Features of Amazon RDS
- It manages software patching, automatic failure detection, backups, and recovery.
- Offers flexibility to opt for automated backups or manual backup snapshots. In case of data loss, you can restore the backups at any time.
- Flexibility to pick your database engine among MySQL, MariaDB, PostgreSQL, Oracle, and Microsoft SQL Server.
- Enable more security with AWS IAM (Identity and Access Management) to ensure that access remains only for the selected users with limited permissions.
Amazon RDS Pricing
Amazon RDS is free to try, and you can test your environment with basic settings. If you are setting up Amazon RDS for your organization with more frequent usage, then the charges depend on the usage of the resources. There are various database engines on which the Amazon RDS pricing depends like Amazon Aurora, My SQL, PostgreSQL, Maria DB, Oracle, and Microsoft SQL Server. On running Amazon RDS, the charges are made on the following parameters.
- On-Demand DB Instances
- Reserved Instances
- Database Storage
- Backup Storage
- Snapshot Export
- Data Transfer

Amazon RDS Tutorial
If you are a beginner and don’t have an AWS account, see our blog on creating an AWS Free Tier Account.
Now, I assume that you already have an AWS account ready with you. To start using Relational Database Service, visit console.aws.amazon.com and log in with your credentials.
Step 1) Create Amazon RDS
After log in to the AWS console, follow the below steps.
1) After visiting your AWS console, search for RDS in the top search bar. Click on the RDS Service as highlighted in the image below.
2) After clicking on the RDS Service, a new window will appear on your screen. You will be provided with two options to create. One is Standard Create which will offer you to choose all the additional settings and configurations. The other is Easy Create, which will automatically pick the default configurations for your RDS. Depending on your need, you can pick any option, but I will pick the Easy Create option for a simple creation process for beginners.
3) Now, you need to pick the RDS Engine. The types of RDS Engines available are Amazon Aurora, My SQL, Maria DB, PostgreSQL, Oracle, and Microsoft SQL Server. Based on your need, you can pick any of the RDS engines. I have picked MySQL in my case.
After selecting RDS Engine, there will be some options to choose the DB instance size, and these options change with the selection you made above. Also, based on your RDS Engine and DB instance size, the payment is made accordingly.
4) Now, in the settings of the Amazon RDS, fill in all the details. First is the DB cluster identifier field. Fill it with the name you want to assign to your database.
Then, assign the username and password for your database. You can also pick the auto-generated password option that will generate a strong password for you.
5) For the Easy Create option, only this much is needed to be configured, and for the rest, all the default settings are used. In the end, all the default settings used for your AWS RDS are shown, and you can match them with your needs.
6) Now, the final step is to click on the Create Database button at the end, as highlighted below.

Step 2) Manage Amazon RDS
After the database is created, you are redirected to the screen where all your databases are present. You can search your database name in the search field if you have multiple databases created. Soon after creating your database, the status is shown. It will take a few minutes to be completely available. From this window, you can also modify and delete your created databases.

Step 3) Connect to Amazon RDS
To connect your database, you need to get the endpoint and port for your database. And to access it, you will require an SQL client.
1) Visit your database by clicking on your created RDS name as highlighted in the above image. Now you will see all the details of your database. Click on connectivity & security and copy your endpoint URL and port number. Both these values are used to connect a database.
2) Download your SQL client and configure it. For the MySQL engine, the MySQL Workbench tool is needed. You can download it from here.
PROMPT> mysql -h <endpoint> -P 3306 -u <mymasteruser> -p
Now, to create a connection to your database, run the above command. After running it, the database is connected to your SQL client.

Frequently Asked Questions
1) What is AWS RDS used for?
Answer: AWS RDS allows the creation, operation, management, and scaling of the relational database in the cloud. It is cost-efficient, and unlike EC2, it doesn’t require setting up the operating system, hardware, and backups manually.
2) Does RDS use EC2?
Answer: RDS and EC2 are both different, and to create RDS, no EC2 is required. RDS is a fully managed service that runs independently over the cloud. But if you want, you can create a database using EC2 alone.
3) Is AWS RDS Saas or Paas?
Answer: AWS is an IaaS (Infrastructure as a Service), but AWS’s RDS service is PaaS (Platform as a Service).
4) Is AWS RDS fully managed?
Answer: Yes, AWS RDS is a fully managed service.
Conclusion
RDS is a Relational Database Service that is easy to set up and configure. To connect, you will need the endpoint and port of the database and the SQL client to access it.
