CompTIA A+ Certification 220-1001: The Total Course - Cloud Computing

The video tutorial introduces cloud computing, explaining how virtual machines in server farms provide remote access. It highlights benefits like rapid elasticity, on-demand resources, and resource pooling. The tutorial covers infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS), emphasizing cost efficiency and ease of use. Examples include Amazon Web Services and Google Docs, illustrating how cloud services have transformed web operations.

What is a key characteristic of cloud computing that allows users to access virtual machines without knowing their physical location?

• Local Hosting

• Remote Access

• Physical Server Management

• Direct Connection

How does cloud computing provide rapid elasticity?

• By increasing the cost of services

• By manually adding more physical servers

• By automatically adjusting resources based on demand

• By reducing the number of users

What is one of the main benefits of resource pooling in cloud computing?

• Shared resources for efficiency

• Reduced data security

• Increased hardware costs

• Limited scalability

Which company is mentioned as a major player in the cloud computing industry?

• IBM

• Amazon Web Services

• Google

• Microsoft

What does Infrastructure as a Service (IaaS) allow users to do?

• Write and deploy code without managing infrastructure

• Access software applications over the internet

• Create and manage virtual machines

• Store data locally on personal devices

Which service model is ideal for developers who want to focus on writing code without worrying about the underlying infrastructure?

• Infrastructure as a Service (IaaS)

• Platform as a Service (PaaS)

• Data as a Service (DaaS)

• Software as a Service (SaaS)

What is an example of Software as a Service (SaaS)?

• Google Docs

• Amazon EC2

• Heroku
