Supporting AWS Utilization for Internal System
Toka Osaka Co., Ltd.
Applied Services: AWS Directory Service, Amazon EC2
Toka Osaka Co., Ltd., a produce wholesaler operating at the Osaka Municipal Wholesale Market since 1964, supplies fruits and vegetables across the Kansai region from domestic and international sources. To modernize their internal IT systems and establish disaster recovery capability, the company deployed a hybrid AWS and on-premises infrastructure with Classmethod's guidance.
Stable, Secure and Low-Cost Operation with AWS
Classmethod designed a hybrid architecture combining on-premises servers with AWS via VPN, with file servers synchronized using Distributed File System (DFS). AWS Directory Service for Microsoft Active Directory enables directory-aware workloads and AWS resources to use managed Active Directory — providing redundancy across both environments.
Architecture Highlights
- • Redundant Active Directory domain controllers across on-premises and AWS
- • Automatic failover capability during on-premises outages
- • Hybrid connectivity via VPN for secure data synchronization
- • DFS file server replication across environments
- • Minimal AWS specifications reduce costs while maintaining resilience
Less Stress and Lower Costs
Through the Classmethod Members support program, Toka Osaka receives Amazon EC2 Reserved Instance discounts and simplified yen-denominated billing — reducing both costs and administrative overhead for the IT team.
Results Achieved
- • Rapid access to internal servers from any location
- • Disaster recovery capability established for business continuity
- • Cost reduction through Reserved Instance discounts
- • Simplified management through Classmethod Members billing support
This case study uses AWS Directory Service and Classmethod Members.
