What is serverless computing?

Serverless computing is indeed best described as a cloud computing model that provisions resources on demand. This model abstracts the underlying infrastructure management, allowing developers to focus solely on writing and deploying code without needing to worry about the servers or specific instances that are running that code.

In serverless computing, the cloud provider automatically handles the scalability, resource allocation, and availability of the applications. This allows for efficient use of resources, as users are only charged for the compute time their code actually uses when it is executed, rather than paying for reserved server capacity regardless of usage. This on-demand nature makes it highly flexible and cost-effective.

This approach contrasts sharply with traditional computing models, where extensive infrastructure management is required. In serverless environments, much of the routine server maintenance, such as scaling up or down based on demand or uptime management, is managed by the cloud provider, freeing developers from these responsibilities.
