Cloud Computing Overview


Cloud computing is a pay-per-use model for enabling available, convenient and on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.“ ~ The National Institute of Standards and Technology (NIST)

Cloud Computing is an internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid. ~ Wikipedia

5 Essential Cloud Computing Characteristics

On-demand self service

Ubiquitous network access (Internet-based)

Resource pooling (achieved by multi-tenant application architecture)

Rapid elasticity/ scalability

Measured service with pay per use


Cloud Computing Layers


Cloud Computing Layers: Comparison


Software as a Service (SaaS)

• Most widely used Cloud Computing approach till date

• Delivers a single application through a browser to thousands of customers using multitenant architecture


Common examples of the SaaS model

IM Email

Photo sharing & management

CRM

Teleconferencing

ERP

CMS Invoicing Collaboration tools


Platform as a Service (PaaS)

• Delivers computing platform and solution stack as a service

• Why PaaS? - Cost savings and faster time to market - Savings in testing and QA efforts - Delivers infrastructure needed to run application over the Internet


Common examples of the PaaS model


Infrastructure as a Service (IaaS)

• The backbone of the entire cloud computing concept

• Delivers complete infrastructure consisting of physical assets servers, storage disks, network devices – as a service

• Control of infrastructure•NO – There is no control over underlying infrastructure•YES – There is control over operating systems, storage and deployment applications


Common examples of IaaS model


Cloud Deployment Models


Cloud Computing Deployment Models

Public• Service provider owned and managed

• Access by Subscription

• Delivers select set of standardized business process, application and/or infrastructure services on a flexible price per use basis

Private • Privately owned and managed.

• Access limited to client and its partner network.

• Drives efficiency, standardization and best practices while retaining greater customization and control

Cloud Computing Skeptics

“The interesting thing about cloud computing is that we've redefined cloud computing to include everything that we already do. I can't think of anything that isn't cloud computing with all of these announcements. The computer industry is the only industry that is more fashion-driven than women's fashion. Maybe I'm an idiot, but I have no idea what anyone is talking about. What is it? It's complete gibberish. It's insane. When is this idiocy going to stop? We'll make cloud computing announcements. I'm not going to fight this thing. But I don't understand what we would do differently in the light of cloud”.

Larry Ellison CEO, Oracle Corporation (2008)


Cloud Computing Champions

“Our industry is going through quite a wave of innovation and it's being powered by a phenomenon which is referred to as the cloud”.

“The cloud services companies of all sizes…The cloud is for everyone. The cloud is a democracy”.

Marc BenioffCEO, Salesforce.com (2010)Steve Ballmer

CEO, Microsoft (2010)
