Essentials of Cloud Computing

What is cloud computing?

• Cloud computing is a type of hardware.

• Cloud computing refers to local data storage.

• Cloud computing is only for large enterprises.

• Cloud computing is the delivery of computing services over the internet.

Name three types of cloud service models.

• IaaS, PaaS, SaaS

• XaaS, YaaS, ZaaS

• AaaS, BaaS, CaaS

• DaaS, FaaS, CaaS

What does IaaS stand for?

• Information as a Service

• Infrastructure as a System

• Infrastructure as a Service

• Integration as a Service

What is the primary benefit of using cloud storage?

• Limited access to data during outages.

• Decreased data security compared to local storage.

• Scalability and accessibility of data from anywhere.

• Increased hardware costs for data storage.

Explain the difference between public and private clouds.

• Private clouds are always more expensive than public clouds.

• Public clouds are only accessible to a single user.

• Public clouds are only for government use.

• Public clouds are shared and accessible to multiple users, while private clouds are exclusive to one organization.

What is a cloud service provider?

• A cloud service provider is a company that sells physical servers.

• A cloud service provider is a company that delivers computing services over the internet.

• A cloud service provider is a software application for managing databases.

• A cloud service provider is a type of hardware used for local storage.

What is the purpose of virtualization in cloud computing?

• To eliminate the need for data security measures.

• The purpose of virtualization in cloud computing is to optimize resource utilization and improve scalability.

• To limit resource access and flexibility.

• To increase hardware costs and complexity.

How does cloud computing enhance collaboration?

• Cloud computing requires physical presence for collaboration.

• Cloud computing decreases the efficiency of team communication.

• Cloud computing limits access to resources to specific locations.

• Cloud computing enhances collaboration by enabling real-time access to shared resources and tools from any location.

What are some common security concerns in cloud computing?

• High-speed internet access

• Cost savings on hardware

• User-friendly interfaces

• Data breaches, loss of data control, account hijacking, insecure APIs, compliance issues.

What is the role of APIs in cloud services?

• APIs facilitate communication and integration between cloud services and applications.

• APIs are primarily for user authentication in cloud services.

• APIs are only used for data storage in cloud services.

• APIs eliminate the need for cloud services altogether.
