The Customer and Its Challenges
A global language learning platform delivers personalized, group-based, and asynchronous training to learners of all levels. Its solutions are used by individuals, schools, and enterprises to improve language proficiency, leveraging video-based lessons, AI-driven interactions, and scalable collaboration tools. As demand for online language learning surged, the platform required a modern, resilient infrastructure to serve learners worldwide.
The platform’s previous cloud environment was struggling to keep pace with rapid growth and rising user expectations. Key challenges included:
- Scalability bottlenecks that limited the ability to support live and recorded teaching sessions at peak times.
- Inconsistent video distribution performance, leading to latency and degraded learning experiences for global users.
- Fragmented security and compliance controls, with uneven encryption and scattered permission management.
- Limited support for innovation, particularly AI-powered captioning, transcription, and assessment capabilities.
- Lack of cost transparency and optimization tools, making it difficult to manage and predict cloud spend.
The Solutions
CloudX partnered with the platform to design and implement a modern AWS-based solution:
- Migrated core workloads from legacy infrastructure to Amazon ECS Fargate for scalable containerized applications.
- Deployed Amazon RDS for SQL Server with Multi-AZ failover to ensure durability and compatibility with existing Microsoft workloads.
- Leveraged Amazon CloudFront and Route 53 for global DNS resolution and content delivery acceleration.
- Implemented Amazon S3 with lifecycle policies for cost-efficient media storage.
- Integrated Amazon Kinesis Video Streams + Amazon SageMaker for real-time AI-powered captioning and multilingual transcription.
- Strengthened compliance with IAM least-privilege access, KMS encryption, CloudTrail auditing, and Config rules.
- Established CI/CD pipelines with CodePipeline and CodeBuild for automated deployments.
- Enabled CloudWatch and X-Ray observability for monitoring, tracing, and proactive remediation.
The Outcomes
The migration transformed the platform’s ability to deliver high-quality learning experiences worldwide. Within weeks, the new AWS environment went live with less than 15 minutes of downtime during cutover. Learners benefited immediately from smoother video playback, faster load times, and real-time multilingual captions, enhancing accessibility and engagement.
From a financial perspective, infrastructure costs decreased by ~30% overall, with storage costs reduced by 40% through lifecycle optimization. Operational efficiency improved through automated monitoring and scaling, reducing manual intervention during peak usage. Importantly, the platform is now able to differentiate itself with AI-driven features, such as automatic captioning and interactive assessments, while maintaining strict compliance with global education data protection standards (FERPA, GDPR, ISO).
With this modern, secure, and scalable AWS foundation, the language learning platform is well positioned to continue its global growth and innovate with AI-powered educational experiences.
