THE IT-BUSINESS DISCONNECT IS GROWING

Business wants A place to

experiment Fast integration Looser IT

restrictions Responsiveness

IT wants Plenty of notice Predictability Stability Justification

Wham!

WHO’S FILLING THE GAP?

Cloud computing

What Cloud Computing “IS NOT”?It is not Network Computing•Application and Data are not confined to any specific Company’s Server•No VPN Access•Encompasses multiple companies, multiple servers and multiple networksIt is not Traditional Outsourcing•Not a contract to host data by 3rdparty Hosting Business•No subcontracting for computing services for specific outside firm

DEFINITION: CLOUD COMPUTING Cloud computing describes a new

supplement, consumption and delivery model for IT services based on Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet.

What’s new?

Acquisition Model: Based on purchasing of services

Business Model: Based on pay for use

Access Model: Over the Internet to ANY device

Technical Model: Scalable, elastic, dynamic, multi-tenant, & sharable

CLOUD COMPUTING: THE LATEST EVOLUTION OF HOSTING

CLOUD COMPUTING:CHARACTERITICS Massive, abstracted infrastructure

Components decided for you Dynamic allocation, scaling,

movement of applications Pay per use No long-term commitments OS, application architecture

independent No hardware or software to install

CLOUD’S CUSTOMERS

Startups Web-based business, SaaS, collaboration services, widget

providers, mobile services, social networking

Small businesses Online businesses, online presence, collaboration,

enterprise integration

Enterprises R&D projects, quick promotions, widgets, online

collaboration, partner integration, social networking, new business ventures

COMPONENTS TO CLOUD COMPUTING Platform-As-A-Service (PaaS)

Delivers a computing platform and/or solution stack as a service

Facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers

Infrastructure-As-A-Service (IaaS) The delivery of computer IasS, typically platform virtualization For example:

Virtual desktops Grid computing

Applications-As-A-Service (AaaS) /Software-As-A-Service (SaaS) Leverages the Cloud in software architecture Eliminates the need to install and run the application on the

customer's own computer Type:

Commercial Government

Massive scale yields economies of scale.

Common infrastructure speeds innovation. Dynamic, automated infrastructure easier

High utilization yields greater ROI. Success drives IT investment.

IT is the business. If your customers succeed, so do you.
