Questions and Answers

How does cloud computing differ from traditional datacenters in terms of infrastructure?

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

What is the shared responsibility model in cloud computing?

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.

What are the responsibilities of the cloud provider in the shared responsibility model?

The cloud provider is responsible for maintaining physical security, power, cooling, and network connectivity.

What are the responsibilities of the consumer in the shared responsibility model?

What are the benefits of reliability and predictability in the cloud?

<p>Reliability ensures system recovery from failures and continued functioning. Predictability allows for confident planning of performance and cost, with resources deployed efficiently and future costs predicted.</p> Signup and view all the answers

What is the shared responsibility model in cloud computing?

<p>The shared responsibility model in cloud computing defines the division of responsibilities between the cloud provider and the consumer. The consumer is responsible for access security and the data that gets ingested into the database. The cloud provider is responsible for maintaining the physical datacenter, network, and hosts.</p> Signup and view all the answers

What is a private cloud?

<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

What is a public cloud?

<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

What is a hybrid cloud?

<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

In a PaaS environment, what responsibilities does the cloud provider have?
