CTW (Japan) uses ACK and Alibaba Cloud services to stabilize high-concurrency IP game platform
Use case typeInfrastructure modernizationUpdated 5 days ago
CTW Inc. operates G123, Japan's No. 1 IP game platform, serving instant-play HTML5 games to a global audience of millions of subscribers. The platform needed to handle high-concurrency traffic spikes, reduce costs, lower latency across regions, and mitigate security risks such as DDoS attacks. CTW migrated game workloads to Alibaba Cloud Container Service for Kubernetes (ACK) and used Alibaba Cloud database, storage, distributed caching, and Microservices Engine (MSE) capabilities to improve elasticity and cloud-native operations.
