Abstract:

Serverless computing has changed the cloud computing paradigm, where developers do not have to worry about where the code is running or any access to the server. Although it is entirely different from infrastructure as a Service (IaaS) or Platform as a Service (PaaS), serverless offers flexibility through the dynamic nature of the application’s usage. This implies that resources are committed, based on certain event occurrences, dynamically, and so both cost and value are optimized. Unlike the traditional models where one would need to over-provision or spend time and effort to control the idle resources as costs are billed on the basis of the actual time spent executing the functions, serverless computing is therefore fitting for solutions with unpredictable usage and demand. Cognitive reasons have influenced the transition to serverless to enhance the speed of delivery, decentralize the conveying of intricacy, and cut on the expenses, majorly in the microservices architectural style and updates to the event-driven applications. Since key cloud service providers such as AWS, Google Cloud, and Azure have introduced serverless capabilities to their services, the technology has emerged in more applications ranging from e-commerce to the Internet of Things. But as with so many things in computer science, it succeeds at the cost of certain downsides, such as server cold start and limitations on processes that can take a long time. To weigh these benefits against the risks, this paper considers prior research, use cases, and data from experiments that explore serverless computing today and in the future of the cloud.
