Authors - Anushka Mukherjee, Rahi Patel, Himja Patel, Ravi Patel Abstract - This paper addresses the cold start problem in several sectors of serverless computing. It investigates how serverless architectures might become more scalable and efficient by using microservices. Recent research is used to describe strategies for eliminating cold start issues and enhancing performance. In real-time applications like e-commerce and IoT, cold start latency is still a major obstacle, even with advances like parallelism and container reuse. Performance of serverless computing can be optimised in a variety of scenarios by leveraging microservices, which offer potential to improve scalability and agility.
