I surely know that computer and mobile users must hear the word cloud computing. Many questions appear in your mind, such as What is Cloud computing, and how can we use it? Is there any computer in the cloud?
Don’t worry; here, you feed your mind about your doubts and misconceptions about cloud computing.
In short, the cloud is a metaphor for the internet. Especially the business owner or big companies use cloud computing to expand their product services online faster and cheaply.

What is the Cloud Computing?
As we discussed above, the cloud is a metaphor for the internet. Cloud Computing is the provision of on-demand computing services on the web. In simple words, rather than managing files and services on the local storage device, you’ll be doing the same over the internet in a cost-efficient.
Models of Cloud Computing
There are two models of cloud computing;
1. Deployment Model
2. Service Model
1. Deployment Model
There are three types of deployment models;
1. Public Cloud
In this type, the cloud infrastructure is available to the public over the internet; cloud service providers own these. This deployment model fits those who want to build cloud infrastructure but save money.
It is ideal for small businesses with a low budget because it is easy for the owner to deploy his IT services on the internet. The significant benefits of cloud computing are scaling with low costs and simplicity of management.
2. Private Cloud
The private cloud is the cloud infrastructure exclusively operated by a single Organization. The organization or a third party can manage this. A private cloud can be expensive for some businesses, but primarily large businesses buy it to increase security, custom storage, and other computing that suits IT requirements.
The main benefit of a private cloud is a high level of security, fully Customizable, and complete control over the cloud server.
3. Hybrid Cloud
A hybrid cloud combines the functionalities of both public and private clouds. A hybrid cloud is the best option for those businesses who want to expand their IT services fully and effectively. The main benefit of this deployment model is its highly flexible and complete enhanced security.
2. Cloud Services of Cloud Computing
There are three major models of cloud services;
- IAAS (Infrastructure as a Service)
- PAAS (Platform as a Service)
- SAAS (Software as a Service)
1. IaaS (Infrastructure as a Service)
IaaS refers to Infrastructure as a Service; it is a cloud service model where users access basic computing infrastructure. IT administrators commonly use them. If your IT organization requires resources like storage or virtual machines, then IaaS is for you.
Your only work is to manage the data, runtime, middleware applications, and OS. At the same time, the other work is handled by the cloud providers.
2. PaaS (Platform as a Service)
Platform as a Service (PaaS) offers cloud-based platforms and runtime environments to develop, test, and manage applications. This model allows users to build and test applications without acquiring, managing and maintaining the architecture.
If your organization needs a platform for creating software applications, Paas is the model for you. You are only required to manage the applications, and the data and other work such as runtime, middleware, OS, servers, storage, and others are handled by service providers.
3. SAAS (Software as a Service)
Software as a Service involves cloud services for hosting and managing your software applications. Software and hardware requirements are satisfied by vendors, so you don’t have to manage any of those aspects of the solution.
If you’d rather not worry about the hassles of owning any IT equipment, the Saas model is fit for you. The Saas service provider handles all components of the solution required by the larger organization.

Cloud computing allows you to access applications and information via the Internet. This means that instead of having a program installed on your computer, you can access it or store it on a remote server. The term “cloud” comes from the image of clouds in the sky, representing the vast network of servers used to store data and make it available online.
Frequently Asked Questions (FAQs)
Q: What are the cons of cloud computing?
There are several potential disadvantages of cloud computing to be aware of, including:
Security risks – as data is stored remotely and accessed via the internet, it can be more vulnerable to hacking and cybercrime.
Dependence on internet connection – if there is an issue with your internet connection, you may not be able to access your data or applications stored in the cloud.
Costs – while cloud computing can offer cost savings compared to traditional IT infrastructure, there can still be significant costs involved, particularly if you need to increase capacity or bandwidth.
Complexity – as cloud computing can involve a complex mix of hardware, software, and networking elements, it can be more difficult
Q: Can I use adobe creative cloud on 2 computers?
Yes. Adobe Creative Cloud is a software service offering from Adobe Systems that gives users access to a collection of software for graphic design, video editing, web development, and photography. As long as you are logged in to your Creative Cloud account, you can install and use the applications on up to two computers simultaneously.
Q: Does Gmail use cloud computing?
Gmail uses cloud computing. Gmail was one of the first cloud-based applications. When it debuted in 2004, it used about 1% of the world’s total cloud capacity.
Q: How long does it take to learn cloud computing?
It depends on what you want to learn. There are different levels of understanding of cloud computing. If you want to get a basic understanding, it probably takes about 10 hours. But if you want to be an expert, it would take years.
Cloud computing is a vast topic and many things to learn about it. You can’t become an expert overnight.
