Abstract : As cloud computing continues to evolve, serverless architectures have gained significant traction due to their scalability, cost-efficiency, and ease of deployment. This research focuses on optimizing serverless architectures for high- throughput systems, specifically leveraging AWS Lambda and DynamoDB. Serverless computing removes the need for managing server infrastructure, allowing developers to focus on writing code while the cloud provider handles scaling, load balancing, and fault tolerance. AWS Lambda, combined with DynamoDB, provides an ideal environment for building applications with varying workloads, offering both flexible execution and efficient data storage solutions. The paper explores key performance optimization techniques for AWS Lambda and DynamoDB, considering their integration to handle high-throughput use cases. It addresses concerns related to function execution time, cold start latency, and resource allocation in Lambda, as well as optimizing data access patterns and throughput capacity in DynamoDB to minimize cost and improve performance. By analyzing the behavior of AWS Lambda in terms of invocation frequency and duration, the research proposes strategies for improving efficiency, such as optimal memory allocation, function-level caching, and avoiding unnecessary re-invocations. Furthermore, the research delves into the design of DynamoDB tables, including partition key selection, global secondary indexes, and item size optimization. Strategies for managing write and read capacity units, as well as reducing table read and write contention, are examined to ensure the system can scale to handle large volumes of requests without significant performance degradation. Emphasis is placed on achieving the right balance between provisioning capacity and using on-demand scaling to meet throughput demands dynamically. Through extensive testing and case studies, the paper demonstrates the effectiveness of these optimization strategies in real-world scenarios, highlighting the performance gains in terms of reduced latency, improved scalability, and optimized cost structures. It provides a roadmap for architects and developers aiming to design and deploy high-throughput serverless systems using AWS Lambda and DynamoDB, ensuring that applications can efficiently handle large-scale workloads while maintaining flexibility, cost control, and high availability.

Keywords : AWS Lambda, DynamoDB, Serverless Architecture, High-Throughput Systems, Performance Optimization, Cold Start Latency, Scalability, Cost-Efficiency.

As cloud computing continues to evolve, serverless architectures have gained significant traction due to their scalability, cost-efficiency, and ease of deployment. This research focuses on optimizing serverless architectures for high- throughput systems, specifically leveraging AWS Lambda and DynamoDB. Serverless computing removes the need for managing server infrastructure, allowing developers to focus on writing code while the cloud provider handles scaling, load balancing, and fault tolerance. AWS Lambda, combined with DynamoDB, provides an ideal environment for building applications with varying workloads, offering both flexible execution and efficient data storage solutions. The paper explores key performance optimization techniques for AWS Lambda and DynamoDB, considering their integration to handle high-throughput use cases. It addresses concerns related to function execution time, cold start latency, and resource allocation in Lambda, as well as optimizing data access patterns and throughput capacity in DynamoDB to minimize cost and improve performance. By analyzing the behavior of AWS Lambda in terms of invocation frequency and duration, the research proposes strategies for improving efficiency, such as optimal memory allocation, function-level caching, and avoiding unnecessary re-invocations. Furthermore, the research delves into the design of DynamoDB tables, including partition key selection, global secondary indexes, and item size optimization. Strategies for managing write and read capacity units, as well as reducing table read and write contention, are examined to ensure the system can scale to handle large volumes of requests without significant performance degradation. Emphasis is placed on achieving the right balance between provisioning capacity and using on-demand scaling to meet throughput demands dynamically. Through extensive testing and case studies, the paper demonstrates the effectiveness of these optimization strategies in real-world scenarios, highlighting the performance gains in terms of reduced latency, improved scalability, and optimized cost structures. It provides a roadmap for architects and developers aiming to design and deploy high-throughput serverless systems using AWS Lambda and DynamoDB, ensuring that applications can efficiently handle large-scale workloads while maintaining flexibility, cost control, and high availability.
