Cloud Explained with a Pizza Analogy!

Cloud Computing is often misunderstood,  shrouded in technical gobbledygook. Once striped this away, we can see the real potential that Cloud offers to Governments wishing to adapt & transform.  Let’s start with a pictorial definition, shown in Figure 1

Figure 1 – Cloud “Pictorial Definition”

Clients in all industries are reaping benefit from Cloud adoption, including:

  1. Speed & Agility – Using cloud to innovate fast. Quickly build cloud applications. Tap into pay-for-use global IT infrastructure.  Cloud offers the platform for Mobile and Social Business .
  2. Empowerment – Giving users the software they need, freeing developers to focus on apps whilst enabling IT to become a service provider.
  3. Economics – Saving time with self-service cloud. Buy just what you need. Shift CAPEX to OPEX. Increase utilisation.

Another confusing facet of Cloud is the so called “Service Model” – with Platform, Infrastructure & Software being offered as a Cloud Service.  The Pizza Analogy is one easy way to understand this, as shown in Figure 2 below.

Pizza as a Service

Sadly, I can’t claim this as “original art”!  I built this picture by simplifying a recent LinkedIn status post, but hope it helps demystify these technical terms!
