Do You Use Cloud Services Today?

You do, but may not realize it...

The Cloud is a common method to deliver services.

What is the “Cloud?”

National Institute of Standards and Technology Definition:Cloud computing is a model for enabling convenient, 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.

Business Definition of Cloud Computing:Cloud computing is a model for enabling cost effective business outcomes through the use of shared application and computing resources and services. The value is better economics in the execution of business processes.

Public Cloud

� Shared infrastructure & computing resources owned & operated by a

provider selling services to the public and private sectors or to the

general public

Private Cloud

� Shared infrastructure & computing resources owned & operated for the

sole benefit of the organization

Hybrid Cloud

� A deployment model in which services are provided to an organization

through the use of both public & private clouds.

There is nothing revolutionary about this.

What is different is that we have reached a point where technology allows greater levels of resource pooling than before.

Virtualization is a Disruptive Technology

Cost Effective

� Standardized & integrated solution lowers total cost of

ownership

� Smaller number of system admins due to the cookie-cutter

design of cloud components and support processes

More Efficient

� Better infrastructure utilization through pooling resources

Power & Cooling Efficiencies

� Shared resources support multiple workloads at higher

utilization
