Setting up, running, and scaling a relational database in the cloud is simple using Amazon Relational Database Service (Amazon RDS). You can concentrate on your apps and company since it manages time-consuming database management activities while providing cost-effective and scalable capacity. Six well-known database engines, including Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle, and Microsoft SQL Server, are available with Amazon RDS.


An effective open source object-relational database system is PostgreSQL. It has been actively developed for more than 15 years, and because to its tried-and-true design, it enjoys a solid reputation for dependability, data integrity, and accuracy.

Hello, PostgreSQL and Amazon RDS

It might be time to start looking for the next generation of ORDMSs now that MySQL is seeing increased competition (Object Relational Database Management System). PostgreSQL is a well-liked database competitor. It offers more than a standard SELECT, INSERT, UPDATE database while matching MySQL’s performance and feature set. Although it has been existed almost as long as MySQL, it has added several impressive capabilities during the past four years, including native JSON data storage, arrays, and an incredibly flexible extensions system. It is the ideal candidate for your company’s database requirements because to its speed, feature set, and data integrity.

PostgreSQL consistently provides non-breaking upgrades that offer speed improvements and new features because it is actively maintained by its enthusiastic community. Updating your RDS instance is as simple as choosing a new version, scheduling the migration at a time that works for your company, or letting RDS upgrade your instance immediately thanks to Amazon’s user-friendly interface.

Making PostgreSQL instances in the Cloud using Amazon Web Services only only one click. Your database deployment, scaling up and down, automated snapshots, redundancy through Amazon’s Availability Zones, and PostgreSQL ensure that your data is secure and sane. So how does one switch from their current database to PostgreSQL? Amazon can handle it. AWS Database Migration Service, or DMS for short, is a new service from Amazon that seamlessly connects with their RDS service to make migration simple and interruption-free. DMS imports your old database configuration onto an RDS instance after reading it and converting it to PostgreSQL.

Why use PostgreSQL

  • Superior data integrity; Matched performance with MariaDB and MySQL; Native JSON; Native Arrays;
  • To suit your application, make your own extensions;
  • design unique data types and functionalities;
  • strong third-party and community support.

Amazon RDS: Why

  • Scale up and down in the cloud in a matter of minutes;
  • utilising Multi-AZ, automatic replication for high availability and redundancy;
  • include VPCs and other AWS services;
  • With AWS DMS, switching to RDS + PostgreSQL is simple;
  • Snapshots make database backups and restores simple.


Since Amazon RDS is a PaaS, it takes care of growing your databases to meet the rising demands of your application. We’ll look at how to scale your RDS instance both vertically and horizontally.

Horizontal Scaling

With a single click on Amazon RDS, you can easily vertically scale up your database.

The only remaining step is to select the new DB instance class.

Obs. : If you are using Multi-AZ for your database, there will be little to no downtime since the standby database will be upgraded first, followed by a failover to the newly larger database.


AWS RDS offers read replicas to help you grow your database horizontally in the event that your application requires higher read performance. Create read-only copies that are synced with your master database using read replicas. And you can accomplish this with AWS:

Now, all you need to do is enter the database instance name and the instance size you choose. You may deploy your read replicas across any region and availability zone, if you would like.

We’re done; you can now horizontally grow your database in a matter of minutes.Conclusion


utilising Amazon RDS for PostgreSQL if you’re searching for a quick, affordable, dependable, and simple to set up option to host your database. You can set up and begin utilising your new, fully managed database service in a few minutes and with a few mouse clicks.
