Amazon RDS for PostgreSQL vs Google Cloud SQL: What are the differences?
Introduction:
Amazon RDS for PostgreSQL and Google Cloud SQL both are fully managed database services that offer PostgreSQL as one of the database engines. However, there are several key differences between them that set them apart. Let's explore these differences in detail.
Pricing Model: Amazon RDS for PostgreSQL offers a pay-as-you-go pricing model where you are billed based on the actual usage, including instance type, storage, and data transfer. On the other hand, Google Cloud SQL has a more simplified pricing model where you pay only for the instance type and storage without any separate charges for data transfer.
Scalability: Amazon RDS for PostgreSQL provides read replicas and Multi-AZ deployments for high availability and scalability. Read replicas allow you to scale the read workload, while Multi-AZ deployments ensure automatic failover in case of any failures. In contrast, Google Cloud SQL supports automatic failover, but it does not have built-in support for read replicas.
Backup and Restore: Amazon RDS for PostgreSQL offers automated backups, which can be configured to occur at specific intervals. It also provides point-in-time recovery, enabling you to restore the database to a specific point in time. Google Cloud SQL also offers automated backups, but it lacks the point-in-time recovery feature.
Management Interface: Amazon RDS for PostgreSQL provides a web-based management console where you can easily perform various management tasks, such as creating and managing database instances, monitoring performance metrics, and configuring security settings. On the other hand, Google Cloud SQL offers a similar web-based management interface called the Cloud Console, which allows you to perform similar tasks.
Integration with Other Services: Amazon RDS for PostgreSQL integrates seamlessly with other AWS services, such as Amazon CloudWatch for monitoring, AWS Identity and Access Management (IAM) for access control, and AWS Database Migration Service for data migration. Google Cloud SQL also integrates well with other Google Cloud services like Stackdriver for monitoring and IAM for access control.
Region Availability: Amazon RDS for PostgreSQL is available in multiple regions across the globe, allowing you to deploy your database instances closer to your users for lower latency. Google Cloud SQL also offers global availability, allowing you to choose from various regions.
In Summary, Amazon RDS for PostgreSQL and Google Cloud SQL have key differences in terms of pricing model, scalability options, backup and restore capabilities, management interface, integration with other services, and region availability.
Considering moving part of our PostgreSQL database infrastructure to the cloud, however, not quite sure between AWS, Heroku, Azure and Google cloud. Things to consider: The main reason is for backing up and centralize all our data in the cloud. With that in mind the main elements are: -Pricing for storage. -Small team. -No need for high throughput. -Support for docker swarm and Kubernetes.
Good balance between easy to manage, pricing, docs and features.
DigitalOcean's offering is pretty solid. Easy to scale, great UI, automatic daily backups, decent pricing.
