What feature does not belong in a private cloud?

cloud computing

  1. Metered billing

  2. Self-service portal

  3. Dial-home support

  4. Rapid elasticity

Show answer
Correct Option: C

AI Explanation

To answer this question, we need to understand the features typically associated with a private cloud.

A private cloud is a cloud computing model where resources are dedicated to a single organization. It provides similar benefits to a public cloud, such as scalability, flexibility, and self-service, but with added control and security.

Let's go through each option to understand why it does or does not belong in a private cloud:

Option A) Metered billing - This option can be present in a private cloud. Metered billing refers to the practice of measuring resource usage and charging users based on that usage. It can help organizations track and manage costs.

Option B) Self-service portal - This option is commonly associated with private clouds. A self-service portal allows users to provision and manage resources on-demand without the need for manual intervention from IT administrators.

Option C) Dial-home support - This option does not typically belong in a private cloud. Dial-home support refers to a feature where devices automatically report their status and performance to a central support system. This feature is more commonly associated with traditional IT infrastructure rather than a private cloud.

Option D) Rapid elasticity - This option is commonly associated with private clouds. Rapid elasticity refers to the ability to quickly scale resources up or down based on demand. It allows organizations to dynamically allocate and deallocate resources as needed.

Based on the above explanations, the correct answer is option C) Dial-home support. This option does not typically belong in a private cloud.

Amazon Web Services is which type of cloud computing distribution model?

cloud computing

  1. Software as a Service

  2. Platform as a Service

  3. Infrastructure as a Service

  4. None of the above

Show answer
Correct Option: C
Explanation:

To answer this question, you need to understand the different types of cloud computing distribution models.

A. Software as a Service (SaaS): This model provides software applications over the internet on a subscription basis. Users do not have to worry about managing the underlying infrastructure or the software itself. Examples of SaaS providers include Salesforce, Dropbox, and Google Workspace.

B. Platform as a Service (PaaS): This model provides a platform for developing, testing, and deploying applications. PaaS providers offer a complete development environment, including operating systems, programming languages, and development tools. Examples of PaaS providers include Heroku, Microsoft Azure App Service, and Google App Engine.

C. Infrastructure as a Service (IaaS): This model provides virtualized computing resources over the internet. It includes virtual machines, storage, and networking capabilities. Users have control over the operating system and applications running on the infrastructure. Examples of IaaS providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.

D. None of the above: This option implies that Amazon Web Services (AWS) does not fall into any of the mentioned cloud computing distribution models.

To determine the correct answer, you need to identify which distribution model AWS falls into.

The correct answer is:

C. Infrastructure as a Service (IaaS)

Explanation: Amazon Web Services (AWS) is a prominent example of an IaaS provider. It offers a wide range of virtualized computing resources, such as EC2 instances, storage services like S3, and networking services like VPC. Users can provision and manage these resources as needed, providing them with the flexibility and control over their infrastructure.

Which of these services is not Platform as a Service?
cloud computing

  1. Force.com

  2. Microsoft Azure

  3. Amazon EC2

  4. Joyent

Show answer
Correct Option: C
Explanation:

To solve this question, the user needs to know the different types of cloud computing services. The three main types of cloud computing services are Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS). SaaS offers software applications over the Internet, IaaS offers virtualized computing resources over the Internet, and PaaS provides a platform for developers to build, test, and deploy applications over the Internet.

Now, let's go through each option and explain why it is right or wrong:

A. Force.com: This option is a PaaS service offered by Salesforce.com. Force.com provides a platform for developers to build and deploy web applications and mobile apps over the Internet. Hence, this is a Platform as a Service.

B. Microsoft Azure: This option is a cloud computing platform and Infrastructure as a Service (IaaS) service offered by Microsoft. Azure provides virtualized computing resources over the Internet, such as virtual machines (VMs) and storage. Thus, this is an Infrastructure as a Service.

C. Amazon EC2: This option is also an IaaS service offered by Amazon Web Services (AWS). Amazon EC2 provides virtualized computing resources over the Internet, such as VMs and storage. Thus, this is an Infrastructure as a Service.

D. Joyent: This option is a cloud computing company that offers Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) services. Joyent provides virtualized computing resources over the Internet, as well as a platform for developers to build and deploy applications over the Internet. Hence, this is both Infrastructure as a Service and Platform as a Service.

Therefore, the answer is: C. Amazon EC2, since it is not a Platform as a Service, but an Infrastructure as a Service.
