Skip to main content What should teams know about Migration from Amazon RDS to PostgreSQL with simplyblock?
Simplyblock provides Kubernetes-native block storage for Migration from Amazon RDS to PostgreSQL, with predictable performance and simpler operations.
Use Case
Migration from Amazon RDS to PostgreSQL
Cut RDS premiums without trading off reliability.
Move from managed RDS to self-hosted PostgreSQL with a modern storage layer built for predictable performance, operational control, and cloud cost efficiency.
75% Potential Storage Cost Reduction
10x Faster I/O for OLTP Workloads
<200µs NVMe P99 Latency
5 min CSI-Based Deployment Time
The Challenge
Why RDS to PostgreSQL Migration Is Hard
Teams often leave RDS for cost and control, but replacing managed storage operations without introducing risk is the difficult part.
RDS Premiums Inflate Total Database Cost
RDS convenience often comes with significant markup on compute and storage. At scale, this directly impacts margins and limits long-term cost planning.
Performance Regressions During and After Migration
Without low-latency storage and clear performance controls, self-hosted PostgreSQL can underperform compared with baseline RDS expectations.
Backup and Recovery Become Operationally Complex
After leaving managed services, teams must rebuild snapshot, cloning, and point-in-time recovery workflows while keeping database consistency intact.
Noisy Neighbor Risk in Shared Clusters
In Kubernetes and multi-tenant environments, one workload can consume disproportionate IOPS and throughput unless QoS is enforced per volume.
The Approach
How Simplyblock Supports RDS to PostgreSQL Migration
A Kubernetes-native NVMe-over-TCP storage platform that simplifies migration and improves post-migration performance economics.
Migration-Ready Persistent Storage for PostgreSQL
Deploy PostgreSQL on Kubernetes with CSI-native storage classes and dynamic provisioning. Keep familiar operational patterns while gaining deeper infrastructure control than managed RDS allows.
- Standard CSI integration for Kubernetes-native provisioning
- Works with existing PostgreSQL operators and deployment models
- No application code changes required
- Predictable storage behavior across staging and production
Cost Reduction Through Thin Provisioning and Tiering
Replace static over-provisioning with thin-provisioned volumes and automatic tiering for colder data blocks. This reduces steady-state storage cost while preserving access patterns.
- Allocate logical capacity without immediate full physical allocation
- Move colder blocks to lower-cost object storage tiers
- Reduce overprovisioning compared to fixed RDS profiles
- Align spend with actual usage over time
Operational Safety with Snapshots, Clones, and Recovery
Use instant copy-on-write snapshots and clones for migration rehearsal, testing, and rollback plans. Build reliable backup and DR workflows without long backup windows.
- Near-instant crash-consistent snapshots
- Fast environment cloning for validation and testing
- Point-in-time recovery friendly storage model
- Lower operational risk during cutover phases
