1. Beyond Desktop : Introducing Cloud Computing

2. What is Cloud Computing
"Cloud Computing", by definition, refers to the on-demand delivery of IT resources and applications via the Internet with pay-as-you-go pricing
Cloud is essentially a flexible, scalable, pay-per-use model for the way IT services are delivered and consumed, typically through short-term contracts
Model for usage-based network access to a common pool of configurable computing resources (e.g. networks, servers, storage systems, applications, and services) that can be provided and used quickly
Cloud computing is a pay-per-use consumption and delivery model that enables real time delivery of configurable computing resources such as networks, servers, storage, applications and services. Typically these are highly scalable resources delivered over the Internet to multiple companies, which pay only for what they use. Cloud delivery models help organizations to scale their investments as they grow in business. They open the door to new business approaches through standardized applications.

3. Deployment Models of Cloud Computing
Dedicated/ Control
Secure
Fixed Cost
Reduced Risk
Private
Shared
Open
Pay-per use
Public
Pick from the best of both worlds
Hybrid
Public: An easily deployed virtual server on a shared hosting infrastructure. Quickly or automatically scale your servers according to work load. Pay-per-use for unlimited computing resource, storage and bandwidth. Choose a cloud with quality service, engineering and infrastructure. Choose carefully to avoid noisy neighbor effect from sharing. Owned by the service provider. Provides great level of efficiency.
Private : Dedicated, Secure, Fixed Cost. A secure virtual data center on your own dedicated infrastructure. Servers and storage can be added and scaled according to your needs. Planned resource capacity with fixed costs and unmetered bandwidth. Financial control and quick IT response to business needs. Having IT control means you also need IT expertise and resources.
Hybrid : Pick from best of both worlds. A mix of dedicated infrastructure and public cloud infrastructure. Cherry-pick the best infrastructure for your different services. Keep data secure and control costs and resources and dedicated infrastructure. Choose public or private cloud for each service according to its performance profile. Requires IT architecture planning, support and expertise !

4. Service Models for Cloud Computing
Infrastructure as a Service (IaaS) :
Virtual machine services accessed over the network, providing compute and/or storage capabilities
Products offered via this mode include the remote delivery (through the Internet) of a full computer infrastructure (e.g., virtual computers, servers, storage devices, etc.)
Provides a hardware platform as a service, such as Amazon EC2 or Oracle Compute Service
Amazon Web Services, Google Compute Engine, Microsoft’s Azure Virtual Machines, Rackspace, GoGrid
Platform-as-a-Service (PaaS) :
Rapid Development at Low cost, private or public offering
Provides organizations with a runtime environment to develop , maintain , manage the application
Provides a software platform as a service, such as Google Apps Engine or Oracle Java Cloud
Google App engine , Microsoft Azure, Salesforce : Force.com
• IaaS: Organizations get computing power and storage capacity. Organizations in this case has complete control over the IT infrastructure including the hosting environment and the applications. However to manage these resources additional IT staff maybe needed. Thus windows Azure offers the IaaS.
Platform as a Service (PaaS): To understand this cloud computing layer one needs to remember the traditional computing model where each application managed locally required hardware, an operating system, a database, middleware, Web servers, and other software. One also needs to remember the team of network, database, and system management experts that are needed to keep everything up and running. With cloud computing, these services are now provided remotely by cloud providers under this layer;

5. Software-as-a-Service (SaaS) :
Applications are delivered through the medium of the Internet as a service
Instead of installing and maintaining software, you simply access it via the Internet, freeing yourself from complex software and hardware management
Free or paid via subscription, accessible from any computer, facilitates collaborative working
Google, Microdoft, Zoho, pixlr, Jaycut, Aviary, Employease, NetSuite, Salesforce
Microsoft Office 365 , Google Apps for Education collaboration suites, and the Salesforce.com Customer Relationship Management (CRM) system, Microsoft Dynamics CRM Online
Offers a complete application functionality that ranges from productivity (e.g., office-type) applications to programs such as those for Customer Relationship Management (CRM) or enterprise-resource management.
