Why AWS is a Smart Choice for Migrating Databases to PostgreSQL
Author: Phil Vacca | 4 min read | April 17, 2025
Enterprises seeking to move away from legacy Oracle databases are increasingly choosing PostgreSQL on AWS for its scalability, high availability, and cloud-native optimizations. AWS provides multiple PostgreSQL deployment options, each designed to accommodate different workload requirements while reducing operational overhead.
Technical Advantages of PostgreSQL on AWS
- Amazon RDS for PostgreSQL: A fully managed service that automates backups, patching, scaling, and failover, allowing enterprises to focus on application development instead of database maintenance. RDS provides Multi-AZ deployments for high availability and read replicas for improved query performance for your PostgreSQL database.
- Amazon Aurora PostgreSQL: A cloud-optimized PostgreSQL-compatible database that offers 5x the performance of standard PostgreSQL by leveraging a distributed, fault-tolerant storage layer. Aurora enables instantaneous failovers, automated replication across regions, and auto-scaling capabilities for unpredictable workloads.
- Amazon EC2 with Self-Managed PostgreSQL: Ideal for enterprises that require full control over their database configurations. This option provides custom tuning of storage, caching, and query execution plans but requires manual high availability and backup management.
- Advanced Security & Compliance: AWS-native services like AWS IAM, KMS encryption, and VPC isolation ensure secure database access. Compliance with SOC, PCI-DSS, HIPAA, and FedRAMP makes AWS PostgreSQL suitable for regulated industries.
