Optimizing Cold Start Performance in Serverless Computing Environments

Serverless computing, also known as Function as a Service (FaaS), simplifies cloud application development by abstracting server management. However, cold start latency, which occurs when initializing the execution environment, poses sig-nificant challenges. This work proposes an Apache Open Whisk-integrated dynamic caching and request routing system to mit-igate cold start latency. By leveraging intelligent caching, the system aims to reduce response times for serverless functions. Comprehensive performance evaluations demonstrate that the proposed system reduced average response times by up to 7 times, while also ensuring efficient resource utilization. These findings provide practical insights and scalable solutions to enhance the efficiency and reliability of serverless architectures, particularly for latency-sensitive applications.
