Top 5 Reasons why you should use RDS service in AWS


Amazon relational database services or Amazon RDS is a service that makes it easy to setup, operate and scale a relational database in the cloud.

You can choose from the new Amazon Aurora engine, MySQL, PostgreSQL, Oracle database or Microsoft SQL server. An AWS even keeps up with patching them for you. You can keep using existing tools and applications.

With Amazon RDS there is no need to buy, rack and stack hardware and no need to install software. Just click and go. New databases will be made available while you do more important stuff.

Top 5 Reasons:

1. Managed and Easy Deployments:

Amazon RDS is designed for developers who want to be capable of all the features of MySQL database. Or who wish to migrate the tools, application and code they use today with their already existing database will remain the same with Amazon RDS too.

As Amazon RDS for MySQL provides access directly to the MySQL database software running on your Amazon RDS DB Instance.

Metrics and Monitoring – Amazon RDS sends metrics to CloudWatch every single minute for each and every database instance that is active with no additional charge.

For your database instance deployments you can use console of AWS management to view key operations like computer, I/O activity, memory, Db Instance connections, and utilization. You can also get a deeper insight in real time with monitoring.

DB Event Notification – Amazon RDS sends you Amazon SNS notification through email or sends you SMS about DB instance deployments.

Automatic Software Patching – Amazon RDS makes sure that MySQL with the latest patches stays up to date.

2. Predictable Performance – Fast:

Amazon RDS provides PIOPS (Provisioned IOPS) to get fast, predictable and consistent input and output performance. For online transaction processing and for high I/O centric application this is ideal.

MySQL RDS allow you to set up as many as 30,000 IOPS. As you set more IOPS the concurrent processes increases. In a result, latency is decreased and throughput is increased to achieve higher database performance.

3. Backup & Recovery:

Amazon RDS facilitate its users with two types of backup mechanisms.

Automated backup: Automated backup automatically takes a full daily snapshot of database’s data. Transaction logs are also captured by Automated backup and any change to your RDS database too.

DB Snapshots: Amazon RDS database snapshots are backups initiated by users. Automated backup takes 1 snapshot daily but with DB instance snapshots user can take as many snapshots as they want.

These DB backups are stored by Amazon RDS. and will be stored until you delete them explicitly.

4. Replication:

Amazon RDS provides two replication features that help you to get enhanced DB availability. It also protects your DB latest updates from any unplanned outcome.

Multi-AZ Deployments – When you create or update your DB instance to run as a multi-AZ Deployment, Amazon RDS automatically manage a “standby” replica.

The replica is created in a different available zone having the independent infrastructure at the separate physical location.

In the case of any failure, Amazon RDS can failover to the latest “standby” so that DB operations will be resumed as soon as possible.

Read Replicas – This feature of Amazon RDS makes it easy to scale it beyond the capacity constraints of a single DB instance. It is for read-heavy DB workloads.

One or more replicas can be created for a source DB instance across AWS region or within the AWS region.

It serves heavy-volume application and read traffic from any copy of your data. Amazon RDS use MySQL’s replication to propagate changes of a source DB Instance to any replica.

5. Security:

Data Encryption – Amazon RDS allow you to secure your MySQL DB Instance with the help of data encryption. You can encrypt it with the keys and it is managed by AWS Key Management Service.

you can isolate your DB Instance using Virtual Private Cloud in your own network. You can connect it to IT- the infrastructure of your industry using your industry encrypted IPSec VPN.
