Comparing Cloud Database Options for PostgreSQL

Severalnines AC


PostgreSQL is world’s most advanced and preferred open source RDBMS for many start-ups, mobile applications and developers.

The traditional way to set up, operate and scale PostgreSQL is time consuming and requires expertise in database systems and PostgreSQL.

There are many vendors which provides cloud platforms for different databases. These solutions come with facilities to make it easy to set up, operate and scale PostgreSQL deployments in the cloud.

Some examples of these services for PostgreSQL are Amazon RDS for PostgreSQL, Google cloud SQL for PostgreSQL, Heroku PostgreSQL, EnterpriseDB cloud database, Microsoft Azure for PostgreSQL, etc.

There are two cloud database environment models.

  1. Traditional cloud model: The content will be run on the particular enterprise infrastructure and any oversight will fall into the shoulders of the IT staff of the company.
  2. Database as a service (DBaaS): It runs on the service providers infrastructure and they (the vendor) would be responsible for any hitches or glitches.

Benefits of a Cloud-Based Database

  1. Increase the speed of getting the application to the market
  2. Easy to set up and administer the database
  3. Getting rid of physical infrastructure.
  4. Developers can focus on the core part of the application instead of managing and maintaining servers.
  5. Ease to take backup
  6. Scale out easily
  7. High availability
