Challenges before introduction

The advantage of real-time strategy simulation games is that they allow the user to play in real time from an omniscient point of view. SLG-type games are popular in the global market and have many users. It was difficult to smoothly provide an environment developed with 3D graphics to many global users.


  • Need a solution that can save resources required for DB installation and operation

  • Civilization Wars is an environment developed with the existing MySQL and must be transferred to the AWS managed DB service.

  • Civilization War is a game developed with massive content in SLG format and 3D graphics and requires high memory usage.

  • As the contents and data of the DB increase, a solution that can expand the storage without interruption for a high user experience is required.

  • You need a security solution to protect the resources in your AWS account and prevent abuse

  • Need a solution that can respond to increasing user traffic for event-based promotions

  • Requires infrastructure design with high availability

  • Requires use of CDN for global content distribution

Smile Shark Solution Proposal

  • Saving resources for initial DB configuration and operation using AWS Managed RDS Aurora.

  • Safely migrate your on-premises environment to an RDS Aurora environment

  • Use the R5 instance type, which is a memory-optimized EC2 type.

  • Enabling Storage Autoscaling for RDS Aurora

  • Enhance account security by enabling Multi-Factor-Authentication (MFA)

  • Configure Auto-Scaling to Respond to Increased Traffic

  • Multi-region configuration for high availability

  • Configuring Amazon CloudFront for Global Content and Fast Distribution

AWS Services used


Effects after introduction

  • Initial configuration of MySQL is provisioned in minutes through Amazon RDS' management console and API calls, saving 50% deployment time

  • Migrate your on-premises MySQL environment to an AWS environment to take advantage of the many benefits of the cloud.

  • Storage autoscaling eliminates the need to provision volumes, improving service continuity and manageability

  • Enabling MFA to protect your account resources from abuse

  • It uses the Auto-Scaling service to handle user traffic from login servers and game servers. 30% improvement in service continuity

  • Continuous service even in the event of a failure due to multi-region configuration
