According to the NIST definition of cloud computing, which characteristic allows users to unilaterally provision computing resources such as server time and network storage without requiring human interaction with the service provider?

An organization runs its entire infrastructure on a single public cloud provider (Google Cloud). All applications, data, and services live in Google Cloud's infrastructure. Which deployment model describes this?

What is virtualization in the context of cloud computing, and why is it fundamental to how cloud providers deliver services?

A company uses two different public cloud providers (AWS for their North American operations and Google Cloud for their European operations) to meet data residency requirements and avoid vendor lock-in. Which deployment model does this represent?

An organization wants to modernize its on-premises applications. The IT team identifies three types of applications: legacy apps that can only move with significant refactoring, custom-built apps that can be containerized and moved as-is, and applications that can be replaced entirely by SaaS solutions. This categorization approach is called what?

Which term describes the model where the cloud provider is responsible for the security of the cloud infrastructure, while the customer is responsible for security within their own cloud environment (data, applications, access management)?
