Azure High Availability and SLAs Quiz

Cloud computing is not constrained by physical infrastructure, unlike traditional datacenters.

The shared responsibility model in cloud computing means that responsibilities for maintaining physical security, power, cooling, and network connectivity are shared between the cloud provider and the consumer.

<p>A private cloud is a cloud that is used by a single entity and provides greater control and security for the company. It can be hosted on-site or in a dedicated off-site datacenter.</p> Signup and view all the answers

<p>A public cloud is a cloud that is built, controlled, and maintained by a third-party cloud provider. It is accessible to anyone who wants to purchase cloud services.</p> Signup and view all the answers

<p>A hybrid cloud is a computing environment that uses both public and private clouds in an interconnected manner. It allows organizations to flexibly choose which services to keep in the public cloud and which to deploy to their private cloud infrastructure.</p> Signup and view all the answers
