Which concept best describes a cloud model that requires no purchase or operation of hardware and optimizes physical resource usage?

Data Lake
VM Cloud
Serverless Computing
Hybrid Cloud

The correct answer is: VM Cloud

The concept that best describes a cloud model that requires no purchase or operation of hardware while optimizing physical resource usage is serverless computing. This model abstracts the underlying infrastructure, allowing developers to focus on writing code without needing to manage servers. In serverless computing, the cloud provider dynamically manages the allocation of resources, scaling automatically based on demand. This optimizes resource utilization since users are only charged for the compute time their code consumes, not for idle server time, making it an efficient choice for many applications. In contrast, other concepts like a data lake focus on storage solutions, while a VM cloud involves managing virtual machines and hardware concerns. A hybrid cloud combines on-premises infrastructure with cloud resources but still involves some operation and management of hardware. This distinction showcases why serverless computing is the most relevant answer in the context of resource optimization and hardware elimination.
