Serverless computing

a) Infrastructure as a Service (IaaS)

• Explanation: IaaS provides virtualized computing resources over the internet. While it reduces the need for physical hardware, users are still responsible for managing the operating system, applications, and middleware, unlike serverless computing, where management is handled by the provider.

b) Platform as a Service (PaaS)

• Explanation: PaaS provides a platform for developers to build applications without managing the underlying hardware or operating systems. However, unlike serverless computing, PaaS may still require some infrastructure management by the user.

c) Software as a Service (SaaS)

• Explanation: SaaS provides complete software applications to users over the internet. Users pay for the service as a subscription and do not manage the underlying infrastructure, but this option still includes paying for the full application, not just specific resource usage.

d) Serverless computing

• Explanation: In serverless computing, the cloud provider manages all aspects of the infrastructure, and users only pay for the resources they consume when their code is running. There is no need to manage servers, and you are billed based on actual usage, such as function execution time.

Hence, Option D Is Correct.

Cloud Computing

What is a Cloud ?

Cloud computing is an application-based software infrastructure that stores data on remote serves, which can be accessed through the internet. To understand how cloud computing works, it can be divided into front-end and backend.

Cloud storage:

Cloud storage is a cloud computing model that stores data on the Internet through a cloud computing provider who manages and operates data storage as a service.Cloud storage allows you to save data and files in an off-site location that you access either through the public internet or a dedicated private network connection.

Benefits of cloud storage

Flexibility and ease of access : Cloud storage means that your data is not tied down to any one location. Various stakeholders can access assets stored on the cloud from a location and device of their choice without any download or installation hassles.

Long-term cost savings :In the long-term, cloud storage can save you significantly in the costs of hardware equipment, storage facilities, power supply, and personnel, which are sure to multiply as your organization grows.

Types of cloud storage:

• Private cloud storage: Private cloud storage is also known as enterprise or internal cloud storage. Data is stored on the company or organization’s intranet. Private cloud storage is a great option for companies with expensive data centers and can manage data privacy in-house. A major advantage of saving data on a private cloud is that it offers complete control to the user. On the other hand, one of the major drawbacks of private cloud storage is the cost and effort of maintenance and updates.
• Public cloud storage: Public cloud storage, the user/company doesn’t need to maintain the system. Public cloud storage is hosted by different solution providers, so there’s very little opportunity for customizing the security fields, as they are common for all users. Public cloud storage is easily scalable, affordable, reliable and offers seamless monitoring and zero maintenance.
• Hybrid cloud storage: Hybrid cloud storage is a combination of private and public cloud storage. In a hybrid cloud, data can be stored on the private cloud, and information processing tasks can be assigned to the public cloud as well, with the help of cloud computing services. Hybrid cloud storage is affordable and offers easy customization and greater user control.
• Community cloud storage: Community cloud storage is a variation of the private cloud storage model, which offers cloud solutions for specific businesses or communities. In this model, cloud storage providers offer their cloud architecture, software and other development tools to meet the community’s requirements. Any data is stored on the community-owned private cloud storage to manage the community’s security and compliance needs. Community cloud storage is a great option for health, financial or legal companies with strict compliance policies.

In the Question:

____________cloud storage is a combination of private and public cloud storage.

The Answer is Hybrid Cloud Storage.

Hence the Option C is Correct.

There are four main services: infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS), and serverless computing.

Software-as-a-service (SaaS) is full applications hosted and managed in the cloud. SaaS users subscribe to an application and access it over the Internet rather than purchasing it once and installing it locally.

In the Question:

Which of the following is a type of cloud computing service?

The Answer is  Software-as-a-Service(SaaS).

Hence the Option C is Correct.
