Exploring Cloud Computing Concepts

What are the three main cloud service models?

• Database as a Service (DBaaS)

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

• Network as a Service (NaaS)

• Function as a Service (FaaS)

How does virtualization enhance cloud computing?

• Virtualization enhances cloud computing by enabling efficient resource utilization, scalability, and improved isolation between environments.

• Virtualization complicates the management of cloud resources.

• Virtualization reduces the need for cloud storage.

• Virtualization limits the number of users accessing cloud services.

What is the difference between public and private cloud deployment models?

• Public clouds are only accessible through a VPN.

• Public clouds are only for government use.

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

• Private clouds are always more expensive than public clouds.

List one benefit of using cloud computing for businesses.

• Scalability

• Decreased collaboration capabilities

• Limited data access

• Increased hardware costs

What is Infrastructure as a Service (IaaS)?

• A model that provides physical servers on-site.

• A platform for developing mobile applications.

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

• A software licensing model for applications.

Explain the concept of Platform as a Service (PaaS).

• PaaS is a type of hardware that requires physical servers.

• Platform as a Service (PaaS) is a cloud computing model that provides a platform for developing, running, and managing applications without the complexity of infrastructure management.

• PaaS is a model for storing data in local databases.

• PaaS is a service that only provides storage solutions.

What are the key characteristics of Software as a Service (SaaS)?

• On-premises installation

• Key characteristics of SaaS include subscription-based pricing, cloud hosting, automatic updates, accessibility, scalability, and multi-tenancy.

• One-time purchase model

• Limited accessibility from mobile devices

How does cloud computing improve scalability for organizations?

• Cloud computing eliminates all IT costs for organizations.

• Cloud computing reduces the need for data storage.

• Cloud computing improves scalability by enabling on-demand resource allocation and flexible pricing models.

• Cloud computing restricts access to resources based on user roles.

What role does virtualization play in resource management in the cloud?

• Virtualization optimizes resource utilization, enables dynamic allocation, and enhances scalability in cloud resource management.

• Virtualization complicates the management of cloud resources.

• Virtualization limits resource allocation to fixed amounts.

• Virtualization reduces the need for physical servers.

Identify a potential risk associated with cloud computing.

• Improved data accessibility for all users.

• Data security risks such as unauthorized access and data breaches.

• Increased hardware costs due to cloud infrastructure.

• Enhanced physical security of data centers.
