Voicy is an audio meme platform with over 500,000 sound clips created by a large community of users.

Challenges:

Voicy faced several challenges driving their collaboration with SotaTek. Their existing Azure-based infrastructure struggled to meet demands, prompting a migration to AWS for improved scalability and performance. Key challenges included:

• Platform migration: Transitioning from Azure to AWS.
• Tight timeline: Completing the migration within a one-month deadline.
• Architecture revamp: Shifting from a monolithic to microservices-based architecture to enhance scalability and flexibility.
• Compatibility issues: Ensuring AWS compatibility with existing services.
• VM dependencies: Resolving inefficiencies due to manual VM maintenance.
• Cost optimization: Reducing operational costs using AWS solutions.

Solutions:

SotaTek devised a tailored solution for Voicy based on the AWS Well-Architected Framework, ensuring a secure, high-performing, and cost-efficient cloud environment.

The architecture was restructured from monolithic to scalable microservices using a robust AWS tech stack, including ECS for containers, RDS for databases, CloudWatch for monitoring, Lambda for serverless operations, and S3 for storage. Database Migration Service (DMS) and DataSync ensured seamless data transfer, while Redshift supported data warehousing, and OpenSearch enhanced search capabilities.

SotaTek refactored code for AWS compatibility, replacing Azure-specific components, while optimizing costs for operational efficiency.

Results:

Voicy successfully transitioned all services from Azure to AWS within the set timeframe, achieving a modern, scalable infrastructure. This migration resulted in a 24% reduction in cloud costs and enhanced scalability through containerized microservices on Amazon ECS.

The multi-AZ deployment ensures high availability, while AWS-managed services streamline operations, allowing Voicy to seamlessly handle user activity surges.
