MUJI Korea Co., Ltd. operates South Korea's MUJI online shopping mall and membership services, offering a broad range of products spanning apparel, household goods, furniture, and food. To maintain service stability and handle significant traffic fluctuations, the company runs its infrastructure on Amazon Web Services (AWS) with support from Classmethod Korea.
Leveraging AWS for Scalability and International Security Standards Compliance
MUJI Korea's e-commerce platform demands elastic scalability and compliance with international security standards. The AWS infrastructure supports core application servers, product imagery storage, and customer database management — all of which must perform reliably during promotional events and seasonal traffic spikes.
"The platform provides elastic scalability and meets international security standards necessary for rapid deployment and operational stability."

A Strategic Partnership with Classmethod Korea
During the early stages of AWS adoption, MUJI Korea faced challenges in cost optimization and operational efficiency. Managing substantial traffic surges without increasing expenses required specialist guidance beyond the team's internal capabilities.
Classmethod Korea stepped in as a strategic technical partner, providing architecture optimization consulting and rapid incident response. The partnership focused on two areas: reducing infrastructure costs through architecture review, and improving operational stability through proactive monitoring and fast support cycles.
Results Achieved
- • AWS costs reduced through optimized architecture and right-sizing
- • Service operations stabilized via rapid technical support and incident management
- • Foundation established for expansion into big data analytics and AI/ML initiatives
Future Vision: Data-Driven Growth
With a stable AWS foundation in place, MUJI Korea is now positioned to pursue its next phase of digital transformation. The company plans to integrate AWS data analytics services and AI/ML capabilities to build personalized recommendation systems and prepare its infrastructure for potential global expansion beyond South Korea.
The partnership with Classmethod Korea continues to evolve — from foundational infrastructure management to enabling advanced data-driven customer experiences that will define the next generation of retail operations.
