what are the Latest cons of cloud computing mcq in 2022
As businesses continue to move their operations online, there are definite benefits to using cloud computing. But before you sign up for a subscription and start uploading your data to the cloud, be sure to weigh all of the pros and cons of using this type of technology. In this article, we’ll take a closer look at some of the potential drawbacks to cloud computing in order to help you make an informed decision.
Cloud computing has several benefits
– Cloud computing can be used to increase productivity
– It can also reduce costs and improve efficiency
– Files can be accessed from anywhere
– There is no need to install software or hardware
However, there are also some cons to cloud computing
1. Security: In order to maintain a secure cloud computing environment, proper security measures must be in place. For example, access to data and servers should be limited to authorized users, and passwords should be encrypted. Furthermore, cloud-based applications may not always be as reliable as their on-premises counterparts.
2. Cost: Although the cost of cloud computing services can be cheaper than traditional solutions, it’s important to keep in mind that this doesn’t always translate into better performance or reliability. Additionally, there are often hidden fees associated with using cloud services, such as monthly subscription fees or additional charges for using certain features.

3. Speed: Because cloud computing relies on remote servers, it can take longer to access data compared to solutions that are located on local computers. This is especially true if the data is located in a remote location and is therefore subject to slower internet speeds.
4. Storage: If you need to store large amounts of data in the cloud, you’ll likely run into storage limitations. In addition, many cloud services don’t offer administrators the ability to back up data or restore it if it becomes corrupted.
Cloud computing can be a privacy and security risk
-Cloud services are not always reliable or secure.
-Your data can be accessed and used by unauthorized individuals.
-The cloud can be a drain on your energy resources.
-You may have to pay for services you use in the cloud.
Types of Cloud Computing
1- Public Cloud
- A public cloud is a cloud that provides cloud services to the user over the Internet. Public cloud is managed by third parties (such as – Amazon, Microsoft and Google etc.).
- Public Cloud can be used by any person with the help of internet. In this, any person can store and access the data.
- In public cloud, you have to pay according to pay-per-use, that is, you have to pay the same amount as you use it.
- This is a better option for those people who have less money. This cloud provides service to more than one user at a time.
- Examples of Public Cloud – IBM SmartCloud Enterprise, Microsoft, Google App Engine, and Windows Azure Services Platform etc.
The computing resources in this cloud are managed by the CSP (Cloud Service Provider).
2- Private Cloud
- Private clouds are those that work on private infrastructure. It is also known as internal or corporate cloud.
- A private cloud is a cloud that is used by a private company. Private cloud is used by the company to manage the data and build its own data centers.
- The security of the private cloud is very high, in this firewall is used to keep the data safe.
- This cloud is managed by the user and the cloud service provider does not provide any services.
- This cloud is divided into two parts on the basis of location and management :- First On-premise Private Cloud and Second Outsourced Private Cloud.
3- Hybrid Cloud
- Hybrid cloud is a combination of public and private cloud i.e. it is made up of public cloud and private cloud. This cloud has the characteristics of both public and private cloud.
- Hybrid cloud is also called heterogeneous cloud, it provides services of both public and private.
- Hybrid clouds are better for organizations or companies that need more security.
- The security of this cloud is better than the public cloud but less than that of the private cloud.
- Examples of hybrid cloud are – Gmail, Google Apps, Google Drive, and MS Office etc.
4- Community Cloud
- Community cloud is a type of distributed system, it is accessed by many organizations and through this these organizations share data among themselves.
- This cloud is managed by one or more organizations or third parties. These clouds are good in terms of security.
- It is much cheaper than other cloud. It is more secure than the public cloud.
- Example of community – Health Care is the community cloud.
Advantages of Cloud Computing
1- It is easy to store and back up data in cloud computing.
2- It is easy to share information in this.
3- In this, the user can access the information stored in the cloud from anywhere in the world using the Internet.
4- The software and hardware used in cloud computing costs less to maintain.
5- In this the user can access the data through mobile.
6- In this, for the services that the user buys, he has to pay only for them.
7- Cloud computing has more memory space to store data like documents, images, audios, videos.
8- It uses a firewall to protect the user’s data, due to which the user’s data remains safe.
Disadvantages of Cloud Computing
1- In cloud computing if we do not have a good internet connection then we cannot access the data and files.
2- It has the biggest disadvantage. In this, the organization or company has to face many problems to transfer its services from one customer to another.
3- We all know that cloud computing is managed and controlled by the service provider, due to which very few users are able to control and access its services.
4- Cloud computing is good in terms of security, but despite this, hackers can steal data while transferring data in it.
Applications of Cloud Computing
It is used in the following places:-
1- Online Data Storage (to store data online)
Cloud computing is used to store files, images and videos on cloud storage. It provides access to cloud storage for data and files.
Apart from this, it is used by the organization to store and access a large amount of data.
2- Backup and Recovery
It is used to back up data. It has many tools to retrieve the lost data which retrieve the lost data.
It is very difficult to recover any lost data but it is not so in cloud computing. It is very easy to recover data in this.
3- Big Data Analysis (in Big Data Analysis)
Cloud computing is used by large companies to analyze the stored data. We all know how difficult it is to analyze a large amount of data, but cloud computing has made this task easy.
4- Testing and Development
It is used to test and develop an application. It is very easy to develop and test the application in this.
There are many tools in cloud computing by which any application can be easily developed and tested.
5- Antivirus (for antivirus)
Cloud computing is a type of antivirus software that monitors the systems in the business and protects them from viruses.
Back when cloud computing technology was not there, businesses had to install antivirus software on their computers, but this is not the case now as it already has an antivirus application.
6- E-commerce (in e-commerce)
Cloud computing is used in e-commerce to store the data of any product online.
One advantage of buying and selling products online is that both the merchant and the customer are able to connect directly with each other and the customer does not have to go to the shop himself. The goods reach the house.

Cloud Computing’s services
- Its full name is infrastructure as a service. It is a service model in which hardware, networking and storage services are provided to the customer in a cloud environment.
- In other words, IaaS is a service where networking devices, databases and web servers provide an infrastructure to the enterprise.
- It is also known as Haas. In this, the user has to pay as much money as he uses it.
- This service model provides operating systems, security, networking and servers for developing applications and services.
- In this model, it is the customer’s responsibility to update the software applications and operating systems that are installed by the customer.
- In this model the user can use computing power and virtual machines without having to manage the server. This model is a good option for those people who have less money.
- Examples of this are: – Google Compute Engine, and Microsoft Azure etc.
- The full name of PaaS is (Platform as a Service). It is a service provider that provides a platform to the customer to create, manage, and deliver software applications with ease.
- This service is used by web developers to create custom applications. In this service, developers do not require data storage, data serving and management to create custom applications.
- PaaS is also commonly called middleware because it is a service model between SaaS and IaaS.
- Examples of this are:- Google App Engine, and Amazon Web Services etc.
- The full name of SaaS is (Software as a Service). It is a specialized computing service used to distribute applications and services over the Internet.
- It is a distribution model that makes software applications (eg:- browsers) available to customers as a service in the Internet.
- The best thing about SaaS is that we do not need to install, maintain, and run any software application in it because all its software applications run directly from the web browser.
- This includes both IaaS and PaaS services.
- In SaaS, the customer’s data is completely secure and the data remains secure even if there is any fault in the system.
- Examples of SaaS applications are:- google apps, and office365 etc.
- The full name of Faas is (Functions as a Service). It is a popular technology that provides a kind of environment or platform for developers to build applications on the Internet.
- This service helps to develop, calculate and execute the user’s code. This service allows the user to develop and update the code without having to maintain the infrastructure.
- Both PaaS and FaaS have the same functionality but differ in terms of cost and scalability.
Cloud Computing is such a computing style that massively scalable and flexible IT-related capabilities are provided as a service with the help of Internet Technologies.
Facilities like infrastructure, platform, application and storage space are available in these services. In this, users use services according to their needs and pay for those services which they use. For this they do not need to build their own infrastructure.

Nowadays there is a lot of competition in the world and in such a situation, people need service on the Internet all the time, that too without any delay. If an application ever freezes, then there is a lot of dissatisfaction among the people. People need the service they need 24/7.
To meet these requirements, we cannot stress on the old mainframe computing, so people used cloud distributed computing technology to solve this problem. Due to which big businesses started doing all their work very easily.
For example, Facebook, which has 757 million active users and who view about 2 million photos daily, around 3 billion photos are uploaded every month, 1 million websites do 50 million operations per second using Facebook.
In such a situation, the traditional computing system cannot solve these problems, rather we need something better that can do this work. That’s why Cloud Distributed Computing is the need of the hour to do such computing.
Examples of Cloud Computing
- YouTube is a great example of cloud storage which hosts video files of millions of users.
- Picasa and Flickr which host digital photographs of crores of users in their servers.
- Google Docs which is another great example of cloud computing which allows users to upload their Presentations, Word Documents and Spreadsheets to their data servers. Along with this, it also gives the option to edit and publish those documents.
It can also be expensive
Cloud computing can be expensive if you have to pay for extra services that you don’t use. For example, if you want to use the cloud to store your photos, you might have to pay for a storage service.
As businesses become more reliant on cloud computing, it has become increasingly important to understand the pros and cons of this technology. In this article, we will explore some of the key benefits and drawbacks of using cloud computing, so that you can make an informed decision about whether or not it is right for your business.
