Understanding Cloud Computing Basics

What are the three main cloud service models?

• Database as a Service (DBaaS)

• Network as a Service (NaaS)

• Function as a Service (FaaS)

• Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS)

Define Infrastructure as a Service (IaaS).

• A type of cloud service that focuses solely on data storage.

• Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet.

• A service that offers software applications over the internet.

• A model that provides physical servers on-site.

What is Platform as a Service (PaaS)?

• A model for hardware virtualization.

• A service for storing data in the cloud.

• Platform as a Service (PaaS) is a cloud computing model that provides a platform for developing, running, and managing applications.

• A type of software for managing databases.

Explain Software as a Service (SaaS).

• Software as a Service (SaaS) is a model where users purchase software licenses upfront.

• SaaS refers to software that must be installed on local servers only.

• Software as a Service (SaaS) is a type of hardware used for data storage.

• Software as a Service (SaaS) is a cloud-based software delivery model where applications are hosted by a service provider and made available to users over the internet.

How does virtualization contribute to cloud computing?

• Virtualization eliminates the need for network security in cloud environments.

• Virtualization slows down application performance in cloud computing.

• Virtualization reduces the need for data storage in cloud computing.

• Virtualization enables efficient resource management and scalability in cloud computing.

What is the role of hypervisors in virtualization?

• Hypervisors are primarily responsible for network security in virtual environments.

• Hypervisors enable virtualization by managing and allocating resources to multiple virtual machines on a single physical host.

• Hypervisors are used to create physical machines from virtual ones.

• Hypervisors only run on dedicated servers without any resource management.

List three benefits of cloud computing.

• 1. Scalability 2. Cost savings 3. Enhanced collaboration

• Limited access to data

• Increased hardware requirements

• Decreased security risks

How does cloud computing enhance scalability?

• Cloud computing provides on-demand resource allocation, enabling easy scaling of computing power and storage.

• Cloud computing reduces the need for additional storage and computing power.

• Cloud computing requires manual intervention for scaling resources.

• Cloud computing limits resource allocation, making scaling difficult.

What is the significance of cost efficiency in cloud computing?

• Cost efficiency increases hardware requirements.

• Cost efficiency is irrelevant to cloud service providers.

• Cost efficiency is significant as it reduces IT costs and enhances resource utilization.

• Cost efficiency only benefits large enterprises.

Explain how cloud computing improves collaboration.

• Cloud computing improves collaboration by enabling real-time access to shared resources, facilitating communication, and ensuring version control.

• Cloud computing only benefits individual users without affecting collaboration.

• Cloud computing reduces the need for teamwork by isolating users.

• Cloud computing eliminates the need for any communication tools.
