“If you think you’ve seen this movie before, you are right. Cloud computing is based on the time-sharing model we leveraged years ago before we could afford our own computers. The idea is to share computing power among many companies and people, thereby reducing the cost of that computing power to those who leverage it. The value of time share and the core value of cloud computing are pretty much the same, only the resources these days are much better and more cost effective.” – David Linthicum

“There was a time when every household, town, farm or village had its own water well. Today, shared public utilities give us access to clean water by simply turning on the tap; cloud computing works in a similar fashion. Just like water from the tap in your kitchen, cloud computing services can be turned on or off quickly as needed. Like at the water company, there is a team of dedicated professionals making sure the service provided is safe, secure and available on a 24/7 basis. When the tap isn't on, not only are you saving water, but you aren't paying for resources you don't currently need.”
Vivek Kundra, CIO, US Federal Government

Risk – Hosted model, common applications
Availability Risk – Professional management reduces downtime

Maximizing Opportunity
Enter new business areas
Respond to client requirements
React to competitive activity
Understand your business more intimately

data centers offer high levels of security especially when compared to mid-size data centers
HTTPs, password protection, encryption help to keep data secure
Audits and reviews still necessary

KEEPING DATA SAFE

data isolation

Private Cloud
Services are delivered on dedicated resources, generally on client premises

Hybrid Cloud
Constant and/or data-sensitive demand is met with a private cloud that can be extended into public cloud capacity

Community Cloud
Private cloud with smaller number of participants

When you have varying workloads

(Windows, Linux, Unix) on a play-as-you-go basis, provisioned and managed remotely

STORAGE aaS

When Should You Use It?
Don’t want hardware locally
Don’t have hardware admin support
Want to avoid capital expense
When you have varying workloads

What is it?

What is it?
Generally, a development platform upon which you can develop (and host) applications without needing knowledge of the underlying infrastructure

When Should You Use It?
No technical support for the underlying platform
Core focus is on the application created, not on the platform itself

via the web
Accessible from anywhere, no local server, pay-per-use or monthly fee, rapid scalability, system maintenance included, reliability

INTEGRATION aaS
