INTRODUCTION
Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over the Internet.
When you store your photos online instead of on your home computer, or use webmail or a social networking site, you are using a “cloud computing” service.
Cloud Computing promotes availability and is composed of
Five essential characteristics
Three service models and
Four deployment models
CHARACTERISTICS
There are five key characteristics of cloud computing:
On-demand self service Broad network access Resource pooling Rapid elasticity and Measured service
SERVICE MODELS
Service Models are the reference models on which the Cloud Computing is based. These can be categorized into three basic service models:
Software as a Service (SaaS) Platform as a Service (PaaS) and Infrastructure as a Service (IaaS)
Cloud ClientsWeb browser, mobile app, clients
PaaSDatabase, web server, deployment
tools
IaaSVirtual machines, storage, networks
SaaSCRM, Email, games, virtual desktopApplication
Platform
Infrastructure
DEPLOYMENT MODELSDeployment models define the type of access to the cloud. These are:
Private cloud Community cloud Public cloud and Hybrid cloud
PURPOSE OF CLOUD COMPUTING
By using the Cloud infrastructure on “pay as used and on demand”, all of us can save in capital and operational investment!
Clients can:Put their data on the platform instead of on their own desktop PCs and/or on their own servers.They can put their applications on the cloud and use the servers within the cloud to do processing and data manipulations etc.
