Cloud computing has brought in many changes in the world considering the transformation of businesses from using old traditional methods to the latest technology. However, the internet plays a major role in the formation of such services. Further, in this blog, we’ll see from where it evolved and ‘what is cloud computing’.
Cloud computing has gained its popularity mainly after Salesforce started using it successfully in 1999. But the fact is, it existed long before that. In 1963, MIT invented a technology that acted as a primitive cloud with two or more people accessing it, which was then described as Virtualization. The concept of Virtualization began shifting with the evolution of the Internet. Businesses began offering virtual computers as a rental service which led to the development of cloud computing in the 1990s.
In 2006, Amazon Web Services was introduced that offered online services to its clients. It also has another site Elastic Compute Cloud that offers virtual computer services to individuals. In the later years, other big firms like Google, IBM, and Oracle started out their different forms of providing cloud computing services.
Let us see ‘What is cloud computing?’ in detail.
What is Cloud Computing?
Cloud Computing has been around since long but the ultimate use of it in enterprises started after Amazon’s AWS, which you could conclude reading the brief history above. Technology has gained its new momentum with the introduction of the internet in almost every field. The same goes with data storage and computing after the introduction of “cloud”.
So, What is Cloud Computing? It is an on-demand availability of computer system resources. In simpler words, it refers to the data resource that can be shared by various users over the internet. It is on-demand access to computing services for various purposes like storage, applications, processing power over the internet and on a pay-as-you-go basis.

Before this technological solution, we were dependent on the traditional business application wherein the hardware played a major role which is a reason why things were complicated. For instance, a team working on the same project could not report about their updates in a single sheet. They need to make individual sheets and the manager fumbles around those separate sheets trying to make out what is the team progress. But with the introduction of Google Sheets, this is possible. A google sheet can be shared by various users through a link and they could update in the same sheet at the same time from different locations and PCs or laptops or even their phones. This is a tiny example of the implementation of cloud computing. It is further divided into different types based on its nature and services.
Types of Cloud Computing
After knowing what is cloud computing, it is eminent that you must be wondering what this wave of cloud technology has vast scopes and could fit into different fields if it was flexible. Well, not all clouds are the same and fit for all. There are three major types of Clouds;
A private cloud refers to cloud computing services used exclusively by a single organization. This private cloud could be located physically on the company’s data center and then delivered to internal users. It hosts its services to a limited number of people.
A public cloud is operated by a third party service provider that delivers servers and storage and other services through the internet. These services are sold on demand and generally on hourly rates. Leading public cloud service providers are Amazon Web Services (AWS), IBM, Microsoft Azure, and Google cloud platform. Some of these providers also offer long term services.
As the name suggests, the hybrid cloud is a combination of both the clouds, private and public. This is a way to amalgamate both the clouds while they serve their own purpose. Many companies invest public cloud for interaction with customers and private cloud for securing their data. But this category often faces performance issues.

Platform as a Service (PaaS)
Platform as a Service often referred to as PaaS, is built on IaaS. It not only offers the infrastructure but also provides a computing platform and solution stack. It offers development tools and business analytics apart from building and upgrading necessary softwares. It manages all the routine maintenance.
Software as a Service (SaaS)
Software as a Service often referred to as SaaS, is the most well-known cloud service. The SaaS providers offer fully functional applications to customers on demand. With SaaS, the end users need not worry about the maintenance or how the underlying infrastructure is worked out, they just need to know how they could use the offered service. It generally on a pay-per-use model.
Other models that could be considered as cloud computing services include Recovery as a Service (RaaS), Storage as a service (STaaS), Security as a service (SECaaS), Data as a service (DaaS), Test environment as a service (TEaaS), Desktop as a service(DaaS), API as a service (APIaaS).
