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:
- 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 .
- Empowerment – Giving users the software they need, freeing developers to focus on apps whilst enabling IT to become a service provider.
- 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.
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!
