Cloud Computing for your organisation? Well, try IaaS   Leave a comment


IaaS, Infrastructure as a Service.

Here’s some questions:
1. Do you have your own datacenter, or are you sharing a facility?
2. What is the age of the infrastructure? That is, the servers and the network switches?
3. How extensive is virtualisation? 100% of your servers? 50% of your servers?
4. And what is in the pipeline for application upgrades and/or replacements or even new applications over the next year or two?

Recently I performed a simple calculation. Given the life of a SAN is say 5 years, it was cheaper to transfer all of its workload to an IaaS provider. That pricing comparison didn’t include the environment (airconditioning, power, etc) and didn’t factor in the reductions in IaaS rates.

Moving to an IaaS provider could be viewed as moving to a remote datacenter?

Think it through. Think through the cost implications, the security implications & what it would mean for your users?

Is this a trend just like server virtualisation was several years ago? Where at first we try virtualising just a few non-critical servers to “test the waters”, and then push through and virtualize the rest.

Perhaps, IaaS makes sense for your situation.
