Which of the following should a systems administrator use to ensure an easy deployment of resources within the cloud provider?

Infrastructure as Code (IaC) allows administrators to define and manage infrastructure resources (like virtual machines, networks, and storage) using configuration files and scripts, rather than manual processes. This enables automated, repeatable, and consistent deployment of resources within a cloud provider, making it easy to provision and scale environments. Software as a Service (SaaS) is a cloud service model where applications are hosted by a third party and made available to users over the internet; it doesn't directly facilitate the deployment of underlying resources. The Internet of Things (IoT) refers to interconnected devices with sensors, software, and other technologies for connecting and exchanging data; it's unrelated to cloud resource deployment. Software-defined networking (SDN) centralizes network control by separating the control plane from the data plane, but it's a networking concept, not a general cloud resource deployment method.
