GREEN VS. CLOUD

What is Cloud Computing?

New Paradigm Shift • Value of On-Line Computing Everything is connected !!! • from World Wide Web to World Wide Computing Make it possible everything as-a-service !!! • Ubiquitous Environments device, whichever you used !!!

It’s Real ! Inevitable ? OverHype ? Everything is going to be on the Cloud !!!

More than 20 definitions in the world !

Definition • Remarkable A pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end-customer applications and billed by consumption. A style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Cloud computing is an emerging approach to shared infrastructure in which large pools of systems are linked together to provide IT services. • For business perspective, Cloud computing is providing IT infrastructure and environment to develop/host/run services and applications, on demand, with pay-as- you-go pricing, as a service.

Nothing New Technology in Cloud Computing

Related Technologies • Grid Computing : Resource abstraction ! • Utility Computing : Pay-as-you-go ! • Web Services : Make it being Interoperable ! • SaaS : Software-as-a-Service ! • + Ubiquitous (in near future) techn ology tion is KEY Virtualiza

Virtualization Technologies

• Public Cloud: the services are delivered to the client via the Internet from a third party service provider. • Private Cloud: these services are managed and provided within the organization. There are less restriction on network bandwidth, fewer security exposures and other legal requirements compared to the public Cloud. • Hybrid Cloud: there is a combination of services provided from public and private Clouds.

Components of Cloud Computing ! Software as a Service (SaaS) Everything as a Service ! Platform as a Service (PaaS) Infrastructure as a Service (IaaS) Network as a Service (NaaS)

Cloud Computing, Today

Challenging to Cloud Computing

Did You Know? • Despite security concerns, 64 percent of large enterprises have already deployed desktop virtualization. Has your organization deployed or does it plan to deploy desktop virtualization?
