How do cloud deployments differ from on-premises deployments?

Cloud deployments often have significantly shorter implementation times as resources can be provisioned rapidly on-demand, whereas on-premises deployments require extensive time for procurement, installation, and configuration of physical hardware.

On-premises deployments generally offer a higher degree of customization for hardware, software, and network configurations because the organization has complete control over its physical infrastructure, while cloud deployments operate within the provider's defined service models.

Cloud deployments involve upgrades and patching for underlying infrastructure and platform services, which are largely managed by the cloud provider, reducing the direct burden on the customer; however, this isn't necessarily 'less frequent' than on-premises but rather a different management model.

Cloud deployments typically operate on a subscription or pay-as-you-go model, moving large capital expenditures (CapEx) for hardware and infrastructure to smaller, recurring operational expenditures (OpEx), resulting in significantly lower initial financial outlays compared to purchasing and setting up on-premises infrastructure.
