Solution

Renesas Electronics, a global semiconductor manufacturer, migrated database workloads from on-premises Exadata Cloud@Customer to Oracle Exadata Database Service on Oracle Cloud Infrastructure to achieve greater global elasticity and low-latency access for users across multiple continents. The migration enabled headquarters in Japan and design centers in Germany to experience consistent sub-millisecond latency through OCI's cross-region networking and distributed architecture, supporting 24/7 global operations with improved performance and reduced infrastructure management burden.

Data flow

Database queries from Japan HQ and Germany design centers distributed across OCI regions via cross-region networking; query results return with minimal latency; semiconductor design and IoT application data stored centrally with regional caching.

Solution architecture

2 components · 2 layers
  1. Compute
    • Oracle Cloud Infrastructure Multi-region architecture with cross-networking enabling low-latency global connectivity from Japan headquarters and Germany design centers.
  2. Storage
    • Oracle Exadata Database Service on OCI High-performance, managed database service providing consistent low-latency access across global regions; eliminates on-premises infrastructure management.

Architecture clues

  • Global distributed cloud regions used to keep latency low for international users
  • Oracle Exadata Database Service deployed on OCI public-cloud regions

Evidence from the source

Renesas runs its core Oracle Database workloads on Oracle Exadata Database Service on OCI to retire aging on-premises infrastructure and maintain global low-latency performance.
