Building a Resilient Hybrid Cloud PostgreSQL DR Architecture with Hitachi VSP One Block and Google Cloud
Modern enterprises face a relentless mandate: zero downtime and absolute data protection. While hybrid cloud strategies are the new standard, extending enterprise-grade Disaster Recovery (DR) into the cloud without sacrificing database performance or ballooning costs has historically been a massive headache.
Traditional secondary data centers are expensive, and standard cloud-native DR often struggles with the ultra-low latency required for mission-critical databases.
Enter a game-changing blueprint from Hitachi Vantara. By combining Hitachi VSP One Block with Google Cloud Platform (GCP), organizations can now build a resilient, scalable, and near real-time DR architecture for PostgreSQL—bridging the gap between on-premises power and cloud agility.
The Secret Sauce: 3 Pillars of the Architecture
This solution removes the database overhead by shifting replication entirely to the storage layer. Here is how the trifecta works:
Hitachi VSP One Block (On-Premises): The heavy lifter. Built on an NVMe flash architecture, this handles your primary production workloads with ultra-low latency, massive IOPS, and enterprise-grade reliability.
VSP One SDS (Google Cloud): The agile target. This software-defined storage acts as your cloud-native replication endpoint, offering elastic scalability, snapshotting, and simplified cloud management without the "noisy neighbor" performance dips common in shared public clouds.
Universal Replicator (UR): The bridge. UR provides journal-based, asynchronous replication between your data center and GCP. Because replication happens at the storage level, your PostgreSQL performance remains completely unaffected while maintaining near real-time synchronization.
Why This Architecture Changes the Game
Traditional disaster recovery solutions often involve costly secondary data centers, complex replication tools, and operational overhead. At the same time, cloud-native DR approaches may struggle to provide the low latency, consistency, and reliability required for mission-critical database workloads.
Deploying this hybrid model isn't just about disaster recovery; it’s about modernizing your entire data strategy.
Slashed RPO & RTO: Continuous, near real-time replication means if disaster strikes, your data is safe and your recovery times are drastically minimized.
Zero Performance Drag: By offloading replication to the storage layer via Universal Replicator, your production databases never skip a beat.
Independent, Cost-Effective Scaling: Scale compute, storage, and performance tiers independently. Combined with built-in thin provisioning and automated data reduction, you only pay for exactly what you need.
Automation Ready: The entire provisioning process is prime for Infrastructure-as-Code (IaC) deployment using Ansible, eliminating manual errors and accelerating setup.
Beyond DR: Because your data is readily available in GCP, this architecture unlocks seamless cloud-bursting, dev/test replication, and database analytics offloading.

The Bottom Line
Hybrid cloud is no longer just about extending infrastructure into the cloud—it’s about building resilient, scalable, and operationally efficient platforms for business-critical workloads.
By combining the performance of Hitachi VSP One Block, the flexibility of VSP One SDS, and the replication intelligence of Universal Replicator, organizations can create a modern PostgreSQL disaster recovery platform that delivers enterprise-grade resilience across on-premises and cloud environments.
For enterprises seeking to modernize disaster recovery while maintaining performance and operational control, this architecture provides a compelling blueprint for the future of hybrid cloud data protection.
With Hitachi VSP One Block, organizations can seamlessly extend existing Hitachi Storage assets across on-premises and cloud environments, simplifying hybrid cloud connectivity and enabling a more flexible and efficient hybrid strategy.
