4. What is the distinction between cloud computing and mobile computing?

The concept of mobile computing is the same as that of cloud computing. Cloud computing uses data from the internet rather than a single device to operate. It gives users access to data that they must retrieve on demand. In mobile, the applications run on a remote server and provide users with storage and management capabilities.

5. What benefits can users derive from utility computing?

Utility computing enables users to pay only for what they use. It is a plug-in manage by an organisation that determines what type of cloud services must be deploy. The majority of businesses prefer a hybrid strategy.

6. How can you secure your data for cloud transport?

Check that there is no leak with the encryption key implemented with the data you are sending to secure your data while transporting it from one location to another.

7. What are the security features of the cloud?

It manages identity and authorises application services.

• Access control: permission must be granted to users in order for them to control the access of another user who enters the cloud environment.
• Authentication and Authorization: Only authorise and authenticate users are permitted to access data and applications.

8. What are the various layers that comprise cloud architecture?

Cloud architecture’s various layers are as follows:

• CLC stands for Cloud Controller.
• SC stands for Walrus Cluster Controller, NC stands for Storage Controller, and Node stands for Node Controller.

9. What are cloud computing system integrators?

The strategy of the complicated process used to design a cloud platform is provided by a systems integrator in cloud computing. Because integrators are experts in the creation of data centres, they can create more accurate hybrid and private cloud networks.

10. What does the term “EUCALYPTUS” stand for?

“EUCALYPTUS” is an acronym that stands for “Elastic Utility Computing Architecture For Linking Your Programs To Useful Systems.”

11. What is the significance of the term “EUCALYPTUS” in cloud computing?

“Eucalyptus” is an open source cloud computing software infrastructure that is use to implement clusters in cloud computing platforms. It is use in the creation of public, hybrid, and private clouds. It can turn your own data centre into a private cloud and allows you to use its functionality in a variety of other organisations.

12. What is the role of a virtualization platform in cloud implementation?

In order to implement cloud computing, a virtualization platform is important.

• Manage the service level agreements.
• Cloud Operating System Virtualization platforms aid in the separation of backend and user level concepts.

13. What are the security laws that are in place to protect data in the cloud?

The security laws that are in place to protect data in the cloud are as follows:

• Control the data that is correctly and completely processed in an application.
• It manages and controls the data that is being manipulate in any of the files.
• Output reconciliation: It is in charge of the data that must be reconcile from input to output.
• Input Validation is the process of controlling the input data.
• Security and backup: It offers security and backup, as well as control over security breach logs.

14. What is the distinction between cloud and traditional datacenters?

• The traditional data centre is more expensive due to heating and hardware/software issues.
• When demand grows, the cloud is scale up. The majority of the costs are incurred in the upkeep of data centres, which is not the case with cloud computing.

15. What are the various types of software as a service (SaaS)?

• Simple multi-tenancy: This mode is efficient because each user has independent resources and is distinct from other users.
• Fine grain multi-tenancy: In this type, resources can be share by many users while maintaining the same functionality.

16. What role do APIs play in cloud services?

APIs (Application Programming Interface) are extremely beneficial in cloud platforms.

• Firstly, it removes the need to write full-fledged programmes.
• It contains the instructions for establishing communication between one or more applications.
• It enables the easy creation of applications and the integration of cloud services with other systems.

17. What are the various data centres used for cloud computing?

Cloud computing is made up of various datacenters, such as:

• Containerized Datacenters
• Low Density Datacenters

18. What exactly is a cloud service in CompTIA Cloud Essentials+?

The cloud service is use to build cloud applications by connecting to a server in a network via the internet. It allows you to use the cloud application without having to install it on your computer. It also reduces the maintenance and support costs for applications developed with cloud services.

19. What are the business advantages of cloud architecture?

The advantages of cloud architecture are as follows:

• There is no infrastructure investment.
• Infrastructure that is just in time
• improved resource utilisation

20. What characteristics distinguish cloud architecture from traditional architecture?

The characteristics that distinguish cloud architecture from traditional architecture are as follows:

• Firstly, Cloud architecture meets the hardware requirements based on demand.
• Secondly, Cloud architecture allows for resource scalability on demand.
• Cloud architecture can manage and handle dynamic workloads without fail.

21. Explain the distinction between elasticity and scalability in cloud computing.

Scalability is a feature of cloud computing that allows an increasing workload to be handle by increasing the amount of resource capacity proportionally. Elasticity, on the other hand, is one of the characteristics that emphasises the concept of commissioning and decommissioning a large amount of resource capacity.

22. Mention how cloud architecture facilitates automation and performance transparency.

Cloud architecture employs a plethora of tools to provide performance transparency and automation. It enables the management of cloud architecture and the monitoring of reports. It also enables them to share the application via cloud architecture. Automation is a critical component of cloud architecture that contributes to higher levels of quality.

23. What is the role of the performance cloud in cloud computing?

The performance cloud is useful for transferring large amounts of data quickly. Professionals involved in high-performance computing research use it.

24. What is the difference between hybrid and community cloud?

• A hybrid cloud is made up of multiple service providers. It combines public and private cloud features. It is use by the company when both private and public clouds are important.
• Community Cloud: This is an expensive model that is use when organisations have common goals and requirements and are willing to share the benefits of the cloud service.

25. What exactly is “on-demand functionality”? How does it work in cloud computing?

Cloud computing allows for instant access to virtualized IT resources. It is usable by the subscriber. It makes use of a share pool to provide resources that can be configure. Networks, servers, storage, applications, and services are all part of the shared pool.

26. What exactly is the public cloud in CompTIA Cloud Essentials+?

The public clouds are available for use and deployment by the general public. Google and Amazon, for example. The public clouds concentrate on a few layers, such as cloud application, infrastructure provision, and platform markets.

27. Define private cloud in CompTIA Cloud Essentials+.

Private clouds are used to secure strategic operations and other purposes. It is a fully functional platform that can be owned, operated, and restricted to a single organisation or industry. Because of security concerns, most organisations have migrated to private clouds. A hosting company employs the use of a virtual private cloud.

28. What is the distinction between cloud computing and traditional datacenters?

Scalability is a feature of cloud computing that allows it to handle increasing workloads by increasing resource capacity proportionally. The architecture uses scalability to provide on-demand resources if the demand is raised by traffic. Elasticity, on the other hand, is a characteristic that allows for the dynamic commissioning and decommissioning of large amounts of resource capacity. It is determine by the rate at which resources are made available on demand as well as their utilisation.

29. What are the benefits of using APIs in cloud services?

APIs (Application Programming Interfaces) are use in cloud platforms for the following reasons:

• Firstly, it provides an alternative method in which you do not need to write a full-fledged programme.
• Secondly, it allows one or more applications to communicate with one another.
• It develops applications and connects cloud services to other systems.

30. How would you secure data for cloud transport?

This is the most obvious question that arises when considering whether or not cloud data is secure. Check that there is no data leak with the encryption key implemented with the data you are sending as it moves from point A to point B in the cloud.
