Hybrid infrastructure database solutions
Hybrid infrastructure database solutions combine on-premises/private infrastructure with cloud resources to run databases efficiently across multiple environments. Instead of keeping all databases only on-premises or fully in the cloud, organizations place workloads where they make the most sense based on performance, cost, security, and compliance.
Typical architecture:
On-Prem / Private Cloud
↕
Public Cloud / Secondary Infrastructure
↕
Database Replication & Synchronization
For enterprise databases such as Oracle, hybrid infrastructure is one of the most common modernization strategies.
Common reasons:
Keep latency-sensitive databases on-premises while using cloud for secondary workloads.
Example:
Private Infrastructure
Cloud
Benefits:
Hybrid enables phased migration.
Example:
Legacy AIX environment
↓
Hybrid AIX + Linux
↓
Cloud-ready infrastructure
This is common in enterprise Oracle modernization.
Cloud becomes a secondary recovery location.
Example:
Primary DB → Private cloud
Standby DB → Secondary environment
Benefits:
Different workloads use different infrastructure.
Mission-critical workloads:
→ High-performance private infrastructure
Secondary workloads:
→ Lower-cost cloud resources
Architecture:
Primary Database
↓ replication
Cloud Standby Database

Benefits:
Different workloads in different locations.
Example:
Benefits:
Databases spread across multiple environments.
Example:
Private Cloud
↓
Cloud A → Production extension
Cloud B → Backup/DR
Benefits:
For distributed enterprises.
Example:
Branch Oracle Database
↓ synchronization
