what is cloud computing with example,A beginner's guide

what is cloud computing in simple terms

In simple terms cloud computing is a technology that provide you cloud base   storage databases

where you can store your data like photo,video's,file,folder and so on. It's same as database like you hard drive but in cloud computing your data will be save on cloud server safely.

and you can access & download your date from anywhere .

Simply put, cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics and more—over the Internet (“the cloud”). Companies offering these computing services are called cloud providers and typically charge for cloud computing services based on usage, similar to how you are billed for water or electricity at home.

1. cloud computing basics Intro with example

The number of cloud storage providers online seems to grow every day. Each competing over the amount of storage they can provide to clients.

Right now, Dropbox is the clear leader in streamlined cloud storage allowing users to access files on any device through its application or website with up to 1 terabyte of free storage.

Google’s email service provider Gmail, on the other hand, provides unlimited storage on the cloud. Gmail has revolutionized the way we send emails and largely responsible for the increased usage of email worldwide.

 step further with their Messenger app, which allows for profiles to exchange data

1. cloud computing Service Models/offerings

         web services stack

Most of the developers are familiar with web services .web services are based on a few simple concepts. 

Every web service accepts a request and returns a response.typically, web services accept one or more input parameters and invoke processing logic that will result in an output.web services are a port of web application that run on a typical stack that has hardware, a server OS, application development platform. For a while think how you can expose every layer that is powering your web application as a web service.

An application programming interface (API) specifies how some software components should interact with each other.

 Different Cloud Computing Service Models :-

Cloud computing basics concept includes all of the following concepts:

IaaS (Infrastructure as a Service) – A computer infrastructure, typically presented in the form of virtualization. Is a service within the concept of cloud hosting.

• It provides a development platform for clients.

• The client needs to install only applications on those platforms. No need to worry about maintaining platforms.

• It requires Programmers to develop applications.

Cloud Computing Providers: Amazon Web Service (AWS); Microsoft Azure; Google Cloud Platform; IBM Blumix; Rackspace; etc.

PaaS (Platform as a Service) – An integrated platform for the development, deployment, testing and support of web-applications. Presented as a service on the basis of the concept of cloud hosting.

• It provides a development platform for clients.

• The client needs to install only applications on those platforms. No need to worry about maintaining platforms.

• It requires Programmers to develop applications.

Cloud Computing Providers: Google App Engine; Microsoft’s Azure Service; Force (SalesForce); etc.

SaaS (Software as a service) – Is the business model of software license, which involves the development and support of the software vendor. Customers also have the opportunity of paid use of it, usually through the Internet.

• Cloud service providers install, operate & maintain software applications in the cloud.

• A client doesn’t need to perform any task, just need to use the applications over the internet.

• It requires only End users to use the applications, no manpower required by clients.

Cloud Computing Networks: Sales-force; Google; SAP; Oracle; Microsoft; and many more.

DaaS (Desktop as a Service) – Another business model license the software, which is a slightly improved model of SaaS, mostly involving the use of multiple services at the same time necessary to complete the work. Was first introduced in the early 2000s.
