What is Cloud Computing?
Cloud computing, also called Utility or On-demand Computing, is the distribution of services like databases, storage, servers, analytics, software, networking, and intelligence across the Internet.
It offers faster innovation, adaptable sources, and economies of range. In fact, the title cloud computing was inspired by the cloud symbol that is utilized to symbolize the Internet.
Types of Cloud Computing
A cloud can either be Public, Private, or Hybrid.
Public cloud services are accessible to every user. They are mainly used by 3rd party service providers. Microsoft Azure is an example of such a cloud.
A private cloud is a data center or an exclusive interface that provides only to a limited user base, with specific settings and access. It is restricted to either one individual or group organization.
Hybrid clouds services are an amalgamation of public and private clouds. Using this technology, you can share applications and data between platforms. It engenders greater flexibility with higher deployment options, thereby helping in efficient optimization.
Types of Cloud Services
There are 3 prime categorical services. The 3 prime categories are – Platform as a service (PaaS), Infrastructure as a service (IaaS), and Software as a service (SaaS).
The types of Cloud Computing Services –
- Platform as a service (PaaS)
This refers to the services that provide an on-demand setting for generating, examining, producing, and managing applications.
In fact, this makes it easier for developers to build a web or mobile app quickly. No worries about setting up or maintaining the foundational infrastructure.
- Infrastructure as a service (IaaS)
This is the most basic category. The user rents IT infrastructure—virtual machines (VMs) and servers, storage, interfaces—from a provider on a pay-as-you-go premise.
- Software as a service (SaaS)
This is a method for delivering applications for software over the Internet, typically on a subscription or else on-demand basis.
What’s more, is that it enables the cloud providers to receive and execute the software application with underlying infrastructure and handle any maintenance.
Users attach to the application, usually with a web browser on their devices, on the Internet.

Benefits of Cloud Computing
Cloud computing is a transformation to a novel stance, from the traditional vision for IT resources. Additionally, it shares a variety of benefits –
Reduced/ Eliminated Capital Expense: This helps in eliminating the capital expense of purchasing software and hardware or establishing and operating on-site datacenters—the server piles, the continuous electricity requirement necessary for power and cooling, a team of IT experts, and more.
Global Scale: It encompasses the ability to diverge elastically. In cloud speak, that means giving the right volume of resources, like more or less computing power, bandwidth, storage exactly when required and from the right geographic location.
Efficient Pace: Most cloud services are self-servicing and on-demand. Thus, even a large amount of computing resources can be easily accounted for in minutes. Hence, this gives businesses flexibility and alleviates the pressure of capacity planning.
Enhanced Productivity: On-site data centers require a lot of “stacking and racking”—hardware installation, software upload, and more.
Cloud computing eliminates the need for most of these tasks. Hence, leaving enough free time for IT teams to achieve more important business goals.
Reliable and Secure: It makes data reserves and strategizes reports. Eventually, making disaster recovery and business continuity easier and less expensive. Moreover, you can always copy the data on various sites for the provider’s network.
A variety of technology and controls are used to protect the data and user base from potential threats.
