Cloud Computing Concepts

In the cloud Shared Responsibility Model, the cloud provider is always responsible for the security [[blank1]] the cloud (physical infrastructure), while the customer is responsible for security [[blank2]] the cloud (data, access, applications).

The three primary cloud service models are IaaS, PaaS, and [[blank1]].

CapEx (Capital Expenditure) is the traditional on-premises model where you buy hardware upfront, while OpEx (Operational Expenditure) is the cloud model where you pay for services as ongoing operating costs.

In cloud computing, the practice of distributing workloads across multiple Availability Zones to ensure the application remains available if one zone fails is called [[blank1]] [[blank2]].

The concept of "high availability" and "fault tolerance" mean the same thing in cloud architecture.
