An IT manager wants to access computing resources on-demand over the internet to reduce upfront hardware costs. Which model would best meet this need?
Client-server computing
Virtualization
Cloud computing
On-premises computing
Cloud computing provides on-demand access to computing resources over the internet, allowing organizations to reduce upfront capital expenditures by paying for resources on a pay-as-you-go basis. Virtualization is a technology that enables multiple operating systems to run on a single physical machine but does not inherently provide services over the internet. On-premises computing involves hosting resources in-house, which requires significant upfront investment in hardware. Client-server computing is a network architecture where client devices request resources from a central server but does not necessarily involve on-demand internet-based resource provisioning.
