Migration of Cloud Infrastructure to Serverless Microservices Architecture for Cost Optimization and Scalability

The client operates a monolithic legacy system that hampers effective modernization, with difficulties in decoupling components, managing APIs lacking proper error handling, logging, and monitoring. Previous migration efforts yielded suboptimal results, leading to high infrastructure costs and inefficient management of their cloud environment. They require a scalable, cost-effective solution that leverages cloud-native architecture to improve system agility and reduce operational overhead.

A mid-sized telecommunications service provider with a complex legacy system seeking modernization to improve operational efficiency and reduce infrastructure costs.

• Achieve a 60% reduction in cloud infrastructure hosting costs through migration to serverless architecture
• Decouple existing monolithic systems into manageable microservices for scalability and maintainability
• Implement a comprehensive API management strategy with robust error handling, logging, and monitoring
• Transition from container-based hosting to a fully cloud-native, serverless environment utilizing best practices
• Enhance the CI/CD pipeline for faster deployment cycles, incorporating automated pre-deployment testing
• Develop a real-time or near-real-time analytics dashboard to provide actionable insights and reduce procurement time and costs

• Migration of existing monolithic applications to microservices architecture using cloud-native, serverless solutions
• Development of lightweight web services with comprehensive API management, including error handling and logging
• Implementation of cloud-native database operations, ensuring high availability and scalability
• Deployment of serverless infrastructure components to remove dependency on traditional container orchestration
• Integration of automated testing within the CI/CD pipeline to speed up deployment and ensure quality
• Development of a real-time analytics dashboard with drilldown capabilities for actionable decision-making
• Incorporation of secure authentication and authorization mechanisms for end-user and administrative access

• APIs for existing legacy systems requiring decoupling and modernization
• Monitoring and logging tools to support error handling and system health checks
• Data ingestion pipelines for real-time analytics and reporting
• Authentication and authorization services for secure access

• Scalability to support rapid growth, with auto-scaling for serverless functions
• High availability and fault tolerance with 99.9% uptime SLA
• Performance targets ensuring low-latency API responses
• Security best practices, including data encryption and secure access controls
• Compliance with industry standards relevant to telecommunications and data privacy

The project aims to reduce cloud infrastructure hosting costs by approximately 60%, improve system scalability and maintainability, and deploy an integrated real-time analytics dashboard. These improvements are expected to enhance operational efficiency, reduce procurement and operational costs, and provide faster deployment cycles, supporting the client’s growth and innovation initiatives.
