Key Benefits of Google Cloud SQL for PostgreSQL
Compatibility
Cloud SQL offers standard
Postgres (9.6 -> 14)
databases .
Use standard connection
drivers and built-in
migration tools to get
started quickly.
Simple & Fully Managed
Easy to use with no
manual software
installation, data backup
or maintenance. HA
option. Integrated
monitoring and alerts.
Performance & Scale
Designed for
performance-intensive
workloads. Easily scale up
to 96 processor cores and
more than 620GB of RAM.
Create databases up to
64TB in size.
Security & Compliance
Automatic data encryption
at rest and in transit. User
controlled network access
with firewall protection.
Cloud SQL is SSAE 16, ISO
27001, PCI DSS v3.0, and
HIPAA compliant.
Cloud SQL for PostgreSQL is innovating rapidly
Logical Replication and Decoding
IAM Database Authentication
Support for 175+ flags and 50+ extensions
In-place upgrades
Cloud SQL Insights
Cost Recommenders with Active Assist
Fully tuned for PostgreSQL
Cloud SQL for PostgreSQL Query & System insights
Query Insights
Cloud SQL Insights is a simple, open tool that helps
developers quickly understand and resolve database
performance issues on Cloud SQL

“Our primary reason to move out of
AWS was because we encountered
various limitations of scale with
DynamoDB. The other big reason was
cost which became untenable at our
scale.”

configuration
Upgrading to paid instance
● Flexible upgrading options from free to paid
● Customers can upgrade anytime during the trial
period
● Customers can also opt-in to auto-upgrade.
● Instances that are not upgraded after 90 days enter a
30 day grace period
● Once upgraded to paid instance, customers can’t
change it back to free instance
