Cloud computing is still unknown to people who don’t belong to IT. But do you know that it was introduced a long time back? Yes, that’s true, and now it is being used in several business sectors. However, it is no longer a much-complicated term used for various modern technologies daily. But, it is still important to know about cloud computing to use its potential. So, don’t worry if you don’t know about cloud computing. In this article, you will learn everything about it. We will also discuss the future aspects of cloud computing in the upcoming years. Please give it a thorough read below.

What is Cloud Computing?
Let me explain it to you in a simple way. Cloud computing helps in computer services delivery, starting from storage applications. All of it is done on the internet. Several services comprise cloud computing. It includes the (SaaS) Software as a Service, Platform as a Service (PaaS), and IaaS (Infrastructure as a Service).
There are three types of deployment in cloud computing– Public, Private, and Hybrid.
- Public– In this cloud, services are given to people available on the internet. A third-party cloud provider maintains it. All the storage, servers, resources are provided from the internet.
- Private– It is a proprietary network that provides hosted services with specific access to limited people. The infrastructure, networking, and computing services are managed and operated from a single organization.
- Hybrid– As you can understand from the name, a hybrid cloud system is a mixture of both private and public. This type of deployment allows the data flow, apps, and information, to share according to the needs.
Furthermore, cloud infrastructure requires both- software as well as hardware infrastructure. It helps to implement the model of cloud computing properly. There are five main aspects of cloud computing. They are- services, storage, data management, devices, and networking.
Thus, the main aim of cloud computing is to provide easy access to IT services.

How does it Work?
Cloud computing enables the client’s devices to access the cloud and data on the internet. It used databases, physical servers to use the applications through the internet. Firstly, the internet connection connects the front end. It comprises browser, network, client device, software applications, etc. Then, it adds up with the back end that includes servers, databases, computers, etc.
To maintain strong communication, a central server manages the whole process. Hence, every application has a dedicated server for effective data flow.
Different Types of Cloud computing
Cloud computing comprises three services as listed below. Read below to understand thoroughly.
SaaS (Software as a Service)
Firstly, this service is also known as software for “on-demand.” You need to know that it is a commonly used cloud computing service. They are used for business customers. It has a wide variety of services, and now it is replacing the traditional ERPs. The users can use this SaaS application on any computer or mobile application with an internet connection. Furthermore, it also augments the supply chain, content management, resource management, customer relationship, etc.
However, the most important part is that SaaS doesn’t require costly licensed programs. It means that users can use different cloud applications as they need accordingly.
PaaS (Platform as a Service)
Secondly, in PaaS, the cloud service providers host the development tools. You, as a user, can get access to useful tools over the internet. For that, you will need APIs, gateway software, etc. On the other hand, PaaS is mainly used to develop software. PaaS is considered the mediator of the cloud service as it links IaaS and SaaS. It comprises networking, storage groundwork, as well as virtual servers. These are essential for designing, managing, developing, implementing, testing, operating, etc.
IaaS (Infrastructure as a Service)
Thirdly, IaaS provides crucial database storage, building blocks, and a virtual platform. You can find various IaaS providers such as AWS (Amazon Web Services). They supply storage APIs to transfer the workload to a machine. Every user gets a storage capacity, and they can access, start and stop accordingly. The providers of IaaS offer medium, large, small, extra-large instances for effective customization. The vendors also hold the responsibility for system maintenance, data backup, and steadiness. Furthermore, with scalable IT and cost-saving solutions, three expensive hardware is effectively outsourced to a third-party vendor.
Benefits and Demerits of Cloud computing
Cloud computing has both benefits and demerits. Some of them are pointed out below.
Some of the benefits of cloud computing are as follows.
Enhanced mobility– with the help of the cloud, data and apps are now accessible to anyone and anywhere.
Increase in Collaboration– cloud computing is particularly developed to improve the work and data flow. Along with that, remote workers can easily communicate with clients.
Flexible Costs– In this, vendors take the responsibility of maintenance that automatically reduces the overall costs.
Easy Operation– It can reduce the complexity of the technology and improve the workflow effectively. The vendors instantly fix any problem whenever it arrives.
Some of the demerits of cloud computing are listed below. Please have a look.
Limited Control– Firstly, cloud computing requires traditional maintenance. The application leader only carries access to the tooling of front-end management of data, services, and apps.
Downtime– Secondly, as many companies use third-party services for cloud computing, it can overload client requests. As a result, it creates financial stoppage. Thus, it is similar to the interest connection failure.
Security-Thirdly, it is one of the main concerns even with renowned companies having the best services. It can threaten the important information available on the cloud due to loopholes.
Hence, overall, cloud computing offers a great future for data management and storage.
In conclusion, cloud computing has immense capability to change the style of the current workflow. With the above information, you can understand that it is not tough to improve the disadvantages. Thus, improved security and strong control can help in boosting businesses across the world.
