APPLICATION OF CLOUD COMPUTING HISTORY OF CLOUD

COMPUTINGCLOUD COMPUTING HAS EVOLVED THROUGH A NUMBER OF PHASES WHICH INCLUDE GRID AND UTILITY COMPUTING, APPLICATION SERVICE PROVISION (ASP), AND SOFTWARE AS A SERVICE (SAAS). THE IDEA OF AN "INTERGALACTIC COMPUTER NETWORK" WAS INTRODUCED IN THE SIXTIES BY J.C.R. LICKLIDER, WHO WAS RESPONSIBLE FOR

ENABLING THE DEVELOPMENT OF ARPANET (ADVANCED RESEARCH PROJECTS AGENCY NETWORK) IN 1969. OTHER EXPERTS ATTRIBUTE THE CLOUD CONCEPT TO COMPUTER SCIENTIST JOHN MCCARTHY WHO PROPOSED THE IDEA OF COMPUTATION BEING DELIVERED AS A PUBLIC UTILITY, SIMILAR TO THE SERVICE BUREAUS WHICH DATE BACK TO THE SIXTIES.

How does cloud computing work

The Infrastructure Will Support The Different Types Of Cloud (Iaas, Paas, Saas, Bpaas). Now; Let’s See How It Works In Reality. Generally, You Log In To A Portal (Enterprise Or Public Wise) And You Order Your Services Through The Cloud Service Consumer. This Service Has Been Created By The Cloud Service Provider And Can Be A Simple Virtual Machine (Vm) Based On An Image, Some Network Components, An Application Service Such As An Webapp Environment And A Service Such As Mongodb. It Depends On The Provider And Type Of Resources And Services. The Cloud Provider Will Validate, Through The Bss, Your Request And If The Validation Is Okay (Credit Card, Contract), It Will Provision The Request Through The

Oss.You Will Receive, In One Way Or Another, The Credentials To Access Your Requested Services And You Will Usually Receive A Monthly Invoice For Your Consumption.

PLATFORM AS A SERVICE (PAAS)

PLATFORM AS A SERVICE (PAAS) IS A CLOUD-BASED COMPUTING ENVIRONMENT DESIGNED TO SUPPORT THE RAPID DEVELOPMENT, RUNNING AND MANAGEMENT OF APPLICATIONS. IT IS INTEGRATED AND ABSTRACTED FROM THE LOWER-LEVEL INFRASTRUCTURE COMPONENTS. THE CAPABILITY PROVIDED TO THE CONSUMER IS TO DEPLOY ONTO THE CLOUD INFRASTRUCTURE CONSUMER-CREATED OR ACQUIRED APPLICATIONS CREATED USING

PROGRAMMING LANGUAGES, LIBRARIES, SERVICES, AND TOOLS SUPPORTED BY THE PROVIDER. 

INFRASTRUCTURE AS A SERVICE (IAAS)

REFERS TO THE UNDERLYING HARDWARE RESOURCES SUCH AS NETWORK, STORAGE AND COMPUTE RESOURCES, USUALLY WITH SOME VIRTUALIZATION TECHNOLOGY. WHILE THE ADVENT OF IAAS OPENED NEW TERRITORY FOR BUSINESSES TO BETTER MANAGE IT HARDWARE COSTS, IT PUT DEVELOPERS IN A CHALLENGING SITUATION.

SOFTWARE AS A SERVICE (SAAS)

REFERS TO THE ACTUAL FUNCTIONAL APPLICATIONS CONSUMABLE ON-DEMAND BY APPLICATION DEVELOPERS, USUALLY MADE AVAILABLE THROUGH PAAS AS A CATALOG OR A MARKETPLACE. OVER THE PAST FEW YEARS,

SEVERAL VENDORS HAVE COME UP WITH THEIR PAAS OFFERINGS, INCLUDING IBM BLUEMIX, FOUNDRY AND MICROSOFT AZURE

Cloud computing applications, or apps, are the cloud-based services also known as Software as a

Service (SaaS). Programs that once had to be installed on computers individually are now offered

online, and the only thing a person needs to access the program is an account and password. These

apps can do everything from keeping track of notes to accounting. For both software providers and

users there are a number of benefits to using cloud based apps:

A. Collaboration: Cloud apps give employees access to their information from anywhere around the

globe. All you need is an Internet connection. This allows more collaborative working as multiple

people can view and edit the same information at once, ensuring your team works efficiently.

B. Automatic Updates: Software as a service (SaaS) allows companies to ensure all users of their

application are on the same version of the software. This is because they can provide automatic

updates to cloud applications, rather than waiting for users to do it themselves. This also helps with

support, as the company will know what version of the software is being used when issues are

logged.

C. Everyone Benefits: Cloud apps allow companies to push new developments to all users at once,

ensuring everyone benefits at the same time.
