A systems administrator is looking for a low-cost application-hosting solution that is cloud-based. Which of the following meets these requirements?

A serverless framework is a cloud-based execution model where the cloud provider dynamically manages the allocation and provisioning of servers. This allows developers to run code without provisioning or managing servers, leading to lower operational costs as you only pay for the compute resources consumed when your code runs. This makes it a low-cost, cloud-based application hosting solution. A Type 1 hypervisor is a bare-metal virtualization platform, not a cloud hosting solution. SD-WAN (Software-Defined Wide Area Network) and SDN (Software-Defined Networking) are networking technologies that optimize network traffic and management, not application hosting solutions.
