Exploring Cloud Computing Concepts

What are the three main cloud computing models?

• PaaS, SaaS, XaaS

• DaaS, FaaS, CaaS

• IaaS, PaaS, SaaS

• IaaS, IaaS, IaaS

Define IaaS and provide an example.

• IaaS (Infrastructure as a Service) is a cloud computing model that provides virtualized computing resources over the internet. An example is Amazon Web Services (AWS) EC2.

• IaaS provides physical hardware for on-premises data centers.

• An example of IaaS is Microsoft Office 365.

• IaaS is a type of software that runs on local servers.

What is the primary difference between PaaS and SaaS?

• SaaS provides a platform for application development.

• PaaS and SaaS are the same and serve identical purposes.

• PaaS is a type of software application for end-users.

• PaaS provides a platform for application development, while SaaS delivers software applications directly to users.

List two advantages of using cloud computing.

• Limited storage

• Slower performance

• 1. Scalability 2. Cost savings

• Increased maintenance

How does a hybrid cloud model differ from a public cloud?

• A hybrid cloud is entirely managed by a single provider.

• A public cloud allows for more customization than a hybrid cloud.

• A hybrid cloud model is only used for private data storage.

• A hybrid cloud model integrates both public and private clouds, while a public cloud is solely managed by a third-party provider.

What is the role of AWS in cloud computing?

• AWS is a social media platform.

• AWS only provides storage solutions.

• AWS is a leading cloud service provider that offers scalable and flexible cloud computing solutions.

• AWS is primarily a hardware manufacturer.

Explain the concept of AWS regions.

• AWS regions are only for data storage without redundancy.

• AWS regions are isolated geographical areas that contain multiple Availability Zones for redundancy and fault tolerance.

• AWS regions are virtual environments for testing applications.

• AWS regions are the same as AWS accounts.

How many availability zones does AWS typically have in a region?

• Only 1

• 5 or more

• 1 or 2

• 3 or more

What are the benefits of using IaaS for businesses?

• Increased hardware costs

• Limited access to resources

• Mandatory long-term contracts

• Benefits of using IaaS include scalability, cost efficiency, flexibility, and reduced maintenance.

Describe a scenario where PaaS would be more beneficial than IaaS.

• A company needing to run a virtual machine for a legacy application.

• A large enterprise migrating its entire data center to a cloud provider.

• A startup developing a web application that needs to focus on coding and deployment without managing infrastructure.

• A team requiring extensive control over hardware configurations for a new project.
