Management of data over the cloud has become a source for increasing the organization’s growth and performance. But, on the other side, it has also created confusion about the cloud-like whether it will provide benefits by using database services or not. Starting with a cloud service requires full-proof planning and strategy. However, to resolve these issues, Amazon has provided a solution for handling the database by getting started with Amazon RDS.
Here, in this blog, we will understand what exactly Amazon RDS is and how it is benefiting the top companies with its unique features. So, let’s get started with it.
What is Amazon RDS?
Amazon RDS is a Relational Database Service used for operating, and scaling a relational database in the cloud. Moreover, it is considered yo be cost-efficient and provides resizable capacity during automating time-consuming administration tasks. Amazon RDS helps you to focus on your applications to get fast performance, high availability, security, and compatibility.
Moving on, below we will be talking about the uniques features of Amazon RDS that make it best in terms of database.
What are the Amazon RDS Features?
Amazon RDS is a fully managed relational database service that comes with database engines. It operates routine database tasks like provisioning, patching, backup, recovery, failure detection, and repair. Moreover, it makes it easy to use replication for enhancing availability and reliability for production workloads. To understand more accurately, check the features mentioned.
1. Lower administrative burden
Easy to use
- In this, you can use the AWS Management Console and the Amazon RDS Command Line Interface for accessing the capabilities of a production-ready relational database in minutes.
Automatic software patching
- Amazon RDS ensures that the relational database software powering your deployment stays up-to-date with the latest patches.
Best practice
- Amazon RDS provides best practice by analyzing configuration and usage metrics from your database instances.
2. Performance
General Purpose (SSD) Storage
- Amazon RDS General Purpose Storage is an SSD-backed storage option for delivering a consistent baseline of 3 IOPS per provisioned GB. Moreover, it provides the ability to burst up to 3,000 IOPS above the baseline.
Provisioned IOPS (SSD) Storage
- Amazon RDS Provisioned IOPS Storage refers to an SSD-backed storage option for delivering fast, predictable, and consistent I/O performance. When creating a database instance, you specify an IOPS rate.
3. Availability and durability
Automated backups
- Amazon RDS has an automated backup feature for enabling point-in-time recovery for your database instance. Moreover, it will backup your database and transaction logs and store both for a user-specified retention period.
Database snapshots
- Database snapshots are user-initiated backups of your instance that are stored in Amazon S3. Moreover, you can create a new instance from database snapshots whenever you desire.
Multi-AZ deployments
- For database instances, Amazon RDS Multi-AZ deployments provide high availability and durability. This makes them a natural fit for production database workloads. However, when you provision a Multi-AZ database instance, then, Amazon RDS synchronously replicates your data for a standby instance for a different Availability Zone (AZ).
4. Security
Encryption at rest and in transit
- Amazon RDS allows the encryption of databases using keys you manage using AWS Key Management Service (KMS). However, data stored at rest in the underlying storage is encrypted on a database running with Amazon RDS encryption. This also includes automated backups, read replicas, and snapshots.
- Further, Amazon RDS has the support of Transparent Data Encryption in SQL Server and Oracle. In which, Transparent Data Encryption in Oracle is integrated with AWS CloudHSM for securely generating, storing, and managing your cryptographic keys in a single-tenant Hardware Security Module.
Network isolation
- AWS recommends running your database instances in Amazon VPC. This will help in isolating your database in your own virtual network and connecting to your on-premises IT infrastructure using encrypted IPsec VPNs.
Resource-level permissions
- Amazon RDS is integrated with AWS Identity and Access Management (IAM). This has the ability to control the actions that your AWS IAM users and groups can take on specific Amazon RDS resources.
5. Manageability
Monitoring and metrics
- Amazon RDS provides Amazon CloudWatch metrics for your database instances at no additional charge. Moreover, you can use the RDS Management Console for viewing key operational metrics, including compute/memory/storage capacity utilization, I/O activity, and instance connections.
Event notifications
- Amazon RDS can notify you via email or text message of database events using Amazon SNS. Moreover, you can use the AWS Management Console or the Amazon RDS APIs for subscribing to over 40 different database events associated with your database instances.
Configuration governance
- Amazon RDS integrates with AWS Config for supporting compliance and enhance security by recording and auditing changes to the configuration of your DB instance including parameter groups, subnet groups, snapshots, security groups, and event subscriptions.
6. Cost-effectiveness
Pay only for what you use
- There is no up-front commitment with Amazon RDS; you simply pay a monthly charge for each database instance that you launch. And, you can delete it after finishing with a database instance.
Reserved instances
- Amazon RDS Reserved Instances give you the option for reserving a DB instance for a one or three-year term and in turn receive a significant discount compared to the On-Demand Instance pricing for the DB instance.
Stop and start
- Amazon RDS allows you to easily stop and start your database instances for up to 7 days at a time. This makes it easy and affordable to use databases for development and test purposes.

Creating an Amazon RDS DB instance
- Firstly, sign in to the AWS Management Console. Then, open the Amazon RDS console at https://console.aws.amazon.com/rds/.
- Secondly, choose the AWS Region in which you want to create the DB instance in the Amazon RDS console.
- Thirdly, in the navigation pane, choose Databases.
- Now, select Create database.
- After that, select Standard Create in the database creation method.
- Next, choose the engine type in Engine options. This can be MariaDB, Microsoft SQL Server, MySQL, Oracle, or PostgreSQL.
- However, if you’re using Oracle or SQL Server for the edition, then, choose the DB engine edition that you want to use.
- MySQL has only one option for the edition, and MariaDB and PostgreSQL have none.
- And, for Version, choose the engine version.
- Further, in Templates, choose the template that matches your use case. If you choose Production, then, follow the preselected in a later step:
- Multi-AZ failover option
- Provisioned IOPS storage option
- Enable deletion protection option
- Now, to enter your master password, do the following:
- Firstly, in the Settings section, open Credential Settings.
- Then, clear the Auto-generate a password check box.
However, the new DB instance uses an automatically-generated password by default for the master user.
- After that, for the leftover sections, specify your DB instance settings.
- Then, select Create database.
- However, the View credential details button appears on the Databases page only if you chose to use an automatically generated password.
- Further, choose View credential details for viewing the master user name and password for the DB instance.
- Then, for connecting to the DB instance as the master user, use the user name and password that appear.
- Lastly, choose the name of the new DB instance for Databases.
- Then, on the RDS console, the details for the new DB instance appear. There the DB instance has a status of creating until the DB instance is created and ready for use. When the state changes to available, then, you can connect to the DB instance.
