What Is Cloud Computing?
Cloud Computing refers to the delivery of computing services on demand. It includes services ranging from the application to storage and processing power. Cloud Computing services generates on the basis of pay-as-you-proceed. The concept of cloud computing is usually used by companies that do not have their own digital infrastructure. The agencies that don’t own digital infrastructure can rent access to storage or application from a cloud service provider.
The concept and mechanism of cloud computing:
The benefits of cloud computing are that by using the concept, the companies can avoid the cost and headache of owning and maintaining computing infrastructure. The companies can simply pay for the services they need and use. In return, cloud service providers can reap the benefits of economies of scale by providing the same services to different firms and companies in need.

Types of Cloud Computing Services
It includes- storage services, artificial intelligence, processing power as well as networking and applications. The sphere of cloud computing is rapidly increasing with a wide range of services.
Mechanism behind it
There is a reason for naming the concept as ‘cloud computing’. The location of the service and other information like the hardware or the operating system on which it is runs is unuseful for the user. So, that is why we use the metaphor of the cloud. It is just like the age-old telephone system as the telephone represented a cloud. That cloud which delivered services. But this is an easy example because for many users the location of the services remains an important issue.
The term ‘cloud computing’ is not new. But the concept of allowing computing services is trending now. Then the emergence of software and the new concepts like Amazon Web Services has added benefit to the historical idea of cloud computing. Developing an infrastructure for cloud computing accounts for more than half of all IT world. The mechanism is becoming more and more significant because the computing workload is increasing day by day.
Models of Cloud Computing
One important model of cloud computing is Infrastructure-as-a-service. It means developing blocks of computing to rent it. This can be servers- physical or virtual or storage and networking. It is useful for the firms that develop applications from the very base and want to control all the options themselves.
Another important model is- Platform-as-a-service. It is basically the next layer. It includes storage, tools and software for the app development, database management and middleware.
The last important model is the Software-as-a-Service. It refers to the delivery of applications. It is the example of cloud computing that most of us use on a daily basis. Now, remember how the underlying operating system is not useful for us (the users). Yes! This is it. We only access the service served on the plate.
The number of cloud service providers is increasing every day. The providers are competing with one another, and we all are reaping the benefit of services. Some examples of it from real life are- Gmail, Dropbox and Facebook. Gmail offers unlimited storage facility on the cloud. Gmail has transformed the manner we send emails and responsible for the growing use of email in the world. Dropbox, on the other hand, provides customers with access files on any device by its application without occupying much storage. Facebook is the blend of these two. It can keep an infinite amount of information, videos and images on the user’s profile. These services can be accessed through any device. Messenger app of Facebook allows the exchange of data.
Why should one use cloud computing services?
Apart from the fact that the usage of cloud computing and its service providers is increasing every day, there are other advantages also. Although, the advantages of this concept depends on the type of service being used. But it is true that the firms using cloud computing are free from the burden of maintaining and buying their own digital infrastructure. Using it means now the companies don’t have to worry about updating applications or software and discarding hardware. Because this has already been taken care of by the service provider. The providers who are experts in services of commodity applications have better skills and more qualified staff compared to a small firm.
By using cloud services companies can save a lot of time too. They will not have to spend time buying or maintaining the infrastructure. So, they can invest that time in moving to new projects quickly and test out new concepts. They can easily avoid additional costs and huge procurement. Firms are also free from the burden of hiring internal staff.
Different technologies of cloud computing
Apart from infrastructure-as-a-service and platform-as-a-service, there are many other technologies associated with cloud computing. One such technology is- Virtualization. Virtualization refers to the process of distributing license keys to physical samples of application among different customers. The main objective of virtualization is to secure a standard version of the cloud service application to all the users. Types of Virtualization includes storage virtualization, hardware virtualization, server virtualization and operating system virtualization.
One other important technology is Service-Oriented Architecture. It refers to the application that separates the services for single business functions and process daily. And it also allows the management related to the cloud to modify and adjust as requested.
Grid computing on the other hand, connects several servers from various places to achieve a common goal.
Future of cloud computing and the potential market
It is not surprising that cloud service spending is increasing faster than expected. Most of the new options and features are being provided as cloud services. The two most commonly used cloud computing services are infrastructure-as-a-service and software-as-a-service. Use of platform-as-a-service is also growing faster. Big firms are now confident that platform-as-a-service is a suitable form of the application development platform. Cloud computing is now a significant branch of mainstream IT sector. Big vendors are trying to dominate the market of cloud services.
The Research predicted that 2/3rd of the spending on cloud services will pass through the top 10 public cloud providers in 2021. It is a proven fact that Alibaba, Amazon, Microsoft are already dominant players in the world market. Because it is cost-effective and easy to adopt, it will continue to grow in the future.
Data is becoming an important weapon, and with that, it is also becoming voluminous. Almost all the companies require a space to safely store their data. So, they are pursuing cloud computing. Because of the Internet of Things, the efficiency and the performance of the internet can be improved. Cloud computing allows that too. Therefore, it will grow more in future due to its numerous benefits.
