Advertising Industry Cloud-Native Migration Case

Client Background

• The client provides network behavior and marketing trend analysis for overseas markets.
• As the platform needed stronger marketing capability, the underlying system had to move to an AWS environment that was easier to scale.

Business Needs

• Reduce system complexity and operational effort while building a repeatable elastic architecture.
• Upgrade MySQL and complete cloud security planning as part of the migration.

Architecture Approach

• Different platforms were deployed across multiple VPCs, with Amazon EKS used for managed container services.
• External traffic was routed through DNS, CDN, and Elastic Load Balancing into the EKS Ingress layer.
• Amazon RDS for MySQL delivered the managed database layer.
• Amazon Kinesis wrote application logs into Amazon S3.
• AWS KMS encrypted data, while Amazon CloudWatch and AWS CloudTrail supported monitoring and auditing.

Business Value

• Managed container and database services reduced ongoing operational complexity and made the platform model easier to reproduce.
• Created a clearer operating pattern for overseas access paths, log handling, and security governance.
• Combined database modernization with migration delivery so the team avoided repeating foundational changes later.
