Cloud computing tutorials for good programmers share frequently asked questions in Linux cloud computing interviews, and continue to bring you Linux cloud computing interview questions on the basis of the contents of the previous article. Let's have a look together.

1. What are the different modes of Software as a Service (SaaS)?

A) simple multi-tenant model: in this mode, each user has independent resources, separate from other users, which is an efficient mode.

B) Fine-grained multi-tenant model: in this model, resources are shared by many tenants, but the functionality remains the same.

2. What is the use of API in cloud services?

API (Application programming Interface) is very useful in cloud platforms.

A) there is no need to write a fully functional program.

B) provides instructions to contact one or more applications.

C) it is easy to build applications and link cloud services to other systems

3. What different data centers are deployed for cloud computing?

Cloud computing includes different data centers, such as

A) containerized data centres

B) low-density data centres

4. What are the different layers in cloud computing?

The different layers of cloud computing include:

A) SaaS: software as a service that gives users direct access to cloud applications without having to install anything on the system.

B) IaaS: infrastructure as a service that provides infrastructure in terms of hardware (such as memory and processor speed, etc.).

C) PaaS: platform as a service, which provides a cloud application platform for developers.

5. How important is the platform as a service?

Platform as a Service (PAAS) is a very important layer in cloud computing. It provides an application platform for providers. It is responsible for providing full virtualization of the infrastructure layer, making it run like a single server.

6. What is a cloud service?

Cloud services are used to build cloud applications over the Internet, using servers in the network. It provides the convenience of using cloud applications directly without having to install them on your computer. It also reduces the work of maintaining and supporting applications developed using cloud services.

Do you know what the three basic clouds are in the field of cloud computing?

A) Professional Cloud

B) Private Cloud

C) High performance Cloud

8. In terms of infrastructure as a service, what resources does it provide?

IAAS (Infrastructure as a Service) provides both virtual and physical resources to build the cloud. It is responsible for handling the complexity of deploying and maintaining the services provided at this layer. Here, the infrastructure is servers, storage systems, and other hardware systems.

9. What are the business benefits of cloud architecture?

The benefits of a cloud architecture include:

A) No infrastructure investment is required

B) timely infrastructure

C) more efficient use of resources

10. Explain what role "EUCALYPTUS" plays in cloud computing.

Eucalyptus is an open source software infrastructure in cloud computing, which is used to implement clusters on cloud computing platforms. It is used to build public, hybrid, and private clouds. It can turn your own data center into a private cloud and allow you to apply its capabilities to many other enterprise organizations.
