What is a key benefit of using a public cloud?

Using a public cloud primarily provides the benefit of outsourcing IT management. When organizations leverage a public cloud service, they are tapping into the infrastructure, platforms, and applications managed by third-party providers. This arrangement allows businesses to redirect their resources away from managing physical servers and other IT operations, focusing instead on their core activities. Vendors responsible for the public cloud handle maintenance, updates, and scaling resources as needed, which can lead to increased efficiency and decreased operational complexity for businesses.

The other options present perspectives that do not align with the characteristics of public cloud technology. The level of control over the infrastructure is often lessened in a public cloud compared to private cloud solutions, security cannot be universally guaranteed as it varies by provider, and there is typically no costly upfront investment required, as costs are generally approached through a subscription or pay-as-you-go model.
