Cloud-based serverless architectures: Trends, challenges and opportunities for modern applications

The paper looks at how cloud computing, which offers flexible, low-cost, and scalable computer resources, has changed the way modern IT infrastructure works. A lot of people are interested in serverless computing because it is cost-effective, uses automatic resource management, and runs programs based on events. In this study, cloud-based serverless architectures are carefully looked at, with a focus on the main ideas, recent changes, problems, and future possibilities. The paper looks at how Function-as-a-Service (FaaS) developed from earlier cloud models like Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). It also talks about how FaaS works with new technologies like blockchain, AI, and the Internet of Things (IoT). Possible study directions are looked into in areas like sustainability, edge computing, and data-heavy workloads. Important issues like scalability, security, and cost management are also looked
