Cloud Computing

What is Cloud Computing?

Cloud Computing refers to the remote control of hardware and software resources, configuration, and access. It provides the storage, infrastructure, and application of data online.

Because the program is not required to be installed locally on a PC, cloud computing gives platform independence. Cloud Computing is therefore mobile and collaborative for our commercial applications.

Basic Concepts

Having cloud computing made viable and available to end-users, several services and models work behind the scene. The models for cloud computing are as follows:

  • Deployment Models
  • Service Models

Deployment Models

Deployment models specify the type of cloud access, i.e., the location of the cloud? There are four different access types: public, private, hybrid, and community.

  • Public Cloud: The public cloud provides easy access for the general public to systems and services. Because of its openness, the public cloud can be less safe.
  • Private cloud: Private cloud enables systems and services within a company to be accessible. Because of its private nature, it is more secure.
  • Community Cloud: The Community Cloud provides access for a set of organizations to systems and services.
  • Hybrid cloud: The hybrid cloud is a public-private cloud that performs key tasks using the private cloud and non-critical activity utilizing the public cloud.

Service Models

Service models are used for cloud computing. The three basic service models are divided into -

  • Anything as a service (XaaS) is another model which includes a network as a service, a business as service, an identity as a service, a database as a service, or a strategy as a service.
  • The most basic level of service is Infrastructure-as-a-Service (IaaS). IaaS offers access to basic resources such as physical equipment, virtual equipment, virtual storage, etc.
  • Platform-as-a-Service (PaaS): PaaS provides an application, development, and deployment tool runtime environment, etc.
  • Software as a service (SaaS): The SaaS model can be used as a service for end-users by software applications.


There are several advantages to cloud computing. Some are listed underneath -

  • Applications can be accessed via the Internet as utilities.
  • An application can always be manipulated and configured online.
  • No software to access or operate cloud applications needs to be installed.
  • Online development and deployment tools enable cloud computing, runtime programming environments via the PaaS paradigm.
  • Network-based cloud resources offer independent platform access to every sort of customer.
  • On-demands self-service cloud computing. Without interaction with the cloud service provider, resources can be used.
  • Highly cost-effective cloud computing since it works with optimum efficiency. It only needs an Internet connection.
  • Cloud Computing provides a more stable load balance.

Cloud Computing

This lesson will help you learn cloud computing principles step-by-step.

What is cloud? 

A network or the Internet is a word cloud, and cloud might be said to be anything in a remote location in other ways. Cloud services can be provided via private and public networks such as WAN, LAN or VPN.

Customer relation management (CRM) runs on cloud, for example on the e-mail system.

Cloud computing, what is it?

Cloud computing refers to the remote manipulation, configuration and access to software, and it offers the storage, infrastructure and application of data online.

Because cloud computing does not have to be locally installed on the pc, the platform independence is available. Cloud computing is therefore mobile and collaborative for our commercial applications.

This reference was made for novices to assist them in understanding basic to advanced Cloud Computing concepts. This lesson gives you sufficient insight about the basics of cloud computing from which to pick up your skills.

You need to have basic information on computers, the internet, databases, and networking ideas before beginning this course. Such basic knowledge will assist you to understand the basics of cloud computing and progress quickly on the path.
