5.1.1 Understanding cloud computing:

• A hybrid cloud combines public and private cloud infrastructure.

  True
• What is an example of a SaaS application?

  Google Docs
• Infrastructure as a Service (IaaS) requires users to manage the underlying hardware.

  False
• Cloud computing reduces both capital and operational expenses
• What is the primary function of cloud computing?

  Deliver services over the internet
• Rapid elasticity in cloud computing means resources can be scaled up or down based on demand

  True
• A public cloud offers services over the public internet
• Order the cloud computing models from least to most user control:

  2️⃣ PaaS

  3️⃣ IaaS
• PaaS offers a platform for developing, testing, and deploying applications
• Match the cloud computing model with its description:

  SaaS ↔️ Access software applications over the internet

  PaaS ↔️ Platform for developing and testing applications

  IaaS ↔️ Access virtualized computing resources
• Cloud-based applications and data can be accessed from anywhere with an internet connection


  True
• One drawback of cloud computing is the risk of data breaches
• What is one area where users have less control in cloud computing compared to on-premises solutions?

  Infrastructure
• In cloud computing, users can provision resources without human interaction with the provider.


  True
• Rapid elasticity in cloud computing allows resources to be scaled up or down based on demand.


  True
• Cloud computing reduces both capital and operational expenses
• What does efficiency in cloud computing aim to reduce?

  Waste
• In the SaaS model, users have the least control over the underlying infrastructure
• Order the cloud computing models based on the level of user control, from least to most.

• What is the primary purpose of cloud computing?

  Deliver services over internet
• Cloud computing provides access to shared computing resources
• Users can provision cloud resources without human interaction in on-demand self-service.


  True
• How do users access cloud computing services?

  Broad network access
• Cloud computing shares resources across multiple users
• Resources in cloud computing can be scaled up or down based on demand.


  True
• What is measured service in cloud computing?

  Resource usage is tracked
• Match the benefit of cloud computing with its description:

  Cost Savings ↔️ Reduces capital and operational expenses

  Scalability ↔️ Easily meets fluctuating demands

  Accessibility ↔️ Access from anywhere with internet

  Efficiency ↔️ Optimizes resource utilization
• Order the types of cloud computing from least to most control for the user.
