This case study highlights the successful system upgrade of a Elearning company in Japan, which faced challenges due to an outdated management system built on Windows and Oracle Database. The upgrade to a cloud-based solution utilized Golang, PostgreSQL, and Kubernetes on Google Cloud Platform to enhance performance, reduce response times, and lower maintenance costs. As a result, the company achieved a remarkable response time of 2 seconds, 99.8% uptime, and a 40% reduction in maintenance expenses, enabling them to expand their operations and attract 30% more students in the first year post-upgrade. This transformation illustrates the significant benefits of modernizing technological infrastructure to support business growth and efficiency.

Challenges

A tutoring company in Japan, with its current management system built on Windows and Oracle Database for nearly 15 years, is unable to meet the growing demand for expansion and technological updates. The old system faces numerous issues such as poor performance, long response times, and increasing maintenance costs. The company requires a more modern solution to effectively manage student and teacher data, as well as support business expansion.

Solution

We conducted an upgrade of the system to a cloud platform using:

• Golang for backend application development, providing high performance and excellent concurrency handling.
• PostgreSQL for efficient database management, ensuring data integrity and scalability.
• Kubernetes for containerization and orchestration, enabling efficient resource utilization and deployment.
• AWS Cloud Platform for robust cloud infrastructure, ensuring high availability and scalability.

Successful Outcomes

• The system was successfully migrated to a cloud-based solution, providing improved performance and reduced maintenance costs.
• The new system achieved a remarkable response time of 2 seconds, 99.8% uptime, and a 40% reduction in maintenance expenses.
• The company was able to expand its operations and attract 30% more students in the first year post-upgrade.

Benefits

• Improved system performance and reduced maintenance costs.
• Increased scalability and flexibility to support business expansion.
• Enhanced data management and improved user experience.
• Reduced operational overhead and improved resource utilization.

Conclusion

The upgrade to a cloud-based solution provided significant benefits to the tutoring company, including improved performance, reduced maintenance costs, and increased scalability.
