Analogies help, don’t they?! So here I am…just one more analogy that may help you understand Cloud Computing modalities i.e IaaS – PaaS – SaaS. If you want to know what IaaS – PaaS – SaaS are? Then this is not the right blog post. But if you find want an analogy that would help you differentiate them, read along…
So, If my Laptop were a cloud:
Hardware
If my Laptop were a cloud, then Laptop Hardware is IaaS (Infrastructure as a Service)
Operating system (OS) on Laptop
If my Laptop were a cloud, then Operating system on Laptop is PaaS (Platform as a Service)
An App (Software) running on Laptop OS
If my Laptop were a cloud, then App running on Laptop OS that you access is SaaS (Software as a Service)
Summary:
Hardware <-> IaaS / Cloud Computing
OS <-> PaaS / Cloud Platform
Apps running on Laptop <-> SaaS / Cloud Services
Remember, it was an analogy, Not technically accurate and so please look at the concepts on your own. But this analogy helps me differentiate concepts and i though it may help someone else..
Do you have other analogies to share? If so, I encourage you to post it as comments!
It’s good to hear a vendor pitch based on bnusseis outcomes, although I’m with Don, the operations cost data is curious. With data centres, operations costs tend to dominate, and this then is where cloud computing could have huge savings potential as they can apply scale to these operations costs. Perhaps the number seems small because they separated power and facilities from operations.
