Challenges
A globally recognized business e-publication owned by a top-tier U.S. university serving executives across 38 industries and eight regions sought to modernize its legacy digital learning and skill development platform by migrating to AWS. The existing monolithic architecture limited scalability, flexibility, and agility—key requirements as the organization planned to expand into new global markets. To support this growth, the client sought a serverless, cloud-native architecture capable of delivering high availability, performance, and security.
Key challenges included:
- Monolithic architecture with tightly coupled components made independent scaling and updates nearly impossible.
- Single point of failure, where a minor issue in one module could disrupt the entire application.
- Complex deployment process requiring after-hours rollouts and extensive regression testing.
- Limited scalability hindered the ability to accommodate increasing subscriber volumes across new geographies.
- High latency in search and content delivery due to lack of regional availability.
- Security concerns around data protection and service reliability.
- No self-healing capabilities, resulting in extended downtime during failures.
- Manual environment provisioning and application deployment processes delayed release cycles.
- Lack of 8×5 operational support for cloud infrastructure, applications, and customer service escalations.
API response times under 100 millisecond, significantly improving user experience
Solution
To address the client’s challenges and enable seamless global scalability, Impetus led a comprehensive transformation of the legacy platform by adopting a modern, serverless, cloud-native architecture on AWS. The solution emphasized modularity, performance, and operational resilience.
Key technology solutions included:
- Microservices architecture: Decomposed the monolithic application into independently deployable services (e.g., user management, subscription, content delivery).
- Containerization: Implemented containerized workloads using Amazon ECS with AWS Fargate for serverless orchestration.
- Serverless operations: Leveraged AWS Lambda for elastic compute, allowing real-time scaling based on user demand.
- Scalable content delivery: Integrated Amazon S3 with CloudFront to enable low-latency content access across geographies.
- Streamlined deployment: Automated CI/CD pipelines using AWS CodeBuild, CodePipeline, and CodeDeploy for faster releases with single-click deployments.
- Robust monitoring: Deployed monitoring and observability stacks using Amazon CloudWatch, X-Ray, and New Relic for real-time performance tracking.
- Security-first approach: Enforced application security with AWS WAF, IAM policies, Amazon Cognito for authentication, and VPC for secure internal communication.
- High availability: Ensured redundancy and resilience through Multi-AZ RDS, auto scaling groups, and disaster recovery configurations.
- Segmented environments: Provisioned dedicated QA, staging, UAT, and production environments for streamlined development and testing.
- Operational support: Provided 8×5 infrastructure and application support, covering over 150 Lambda functions, 20 APIs, RDS instances, Elasticsearch, and CloudFront.
