What is Cloud Computing?
In the simplest terms, cloud computing means storing and accessing data and programs over the web rather than your computer’s disk drive.
Cloud computing is an internet-based computing service during which large groups of remote servers are networked to allow centralized data storage and online access to computer services or resources.
Cloud computing can be used by organizations as shared computing and storage resources instead of building, operating, and improving infrastructure on their own.
- Users can provision and release resources on-demand.
- Resources are often scaled up or down automatically, relying on the load.
- Cloud service providers can enable a pay-as-you-go model, where customers are charged supported the type of resources and per user.
Types of Clouds
There are three kinds of clouds − Public, Private, and Hybrid cloud.
A public cloud could even be a platform that uses the quality cloud computing model to form resources, like virtual machines (VMs), applications or storage, available to users remotely.
A private cloud also provides almost similar features as public cloud, but the info and services are managed by the organization or by the third party just for the customer’s organization. During this sort of cloud, major control is over the infrastructure so security-related issues are minimized.
A hybrid cloud could also be a mixture of both private and public clouds. The selection to run on private or public clouds usually depends on various parameters just like the sensitivity of data and applications, industry certifications and required standards, regulations, etc.
Who is using cloud computing?

With a SaaS offering, you’re doing not got to believe how the service is maintained or how the underlying infrastructure is managed; you simply need to believe how you’ll use that specific piece software.
Who can take up Cloud Computing?
To become a cloud computing professional, one needn’t possess selected educational eligibility. However, candidates with IT or computer-related backgrounds are preferred because of having a basic knowledge of computers and programming. Knowledge of cloud computing basics or any relevant experience could be a superb adds on.
