Vladimir Jirasek, non executive director CSA UK & Ireland and member of CAMM, speaks from bitter experience about a cloud heist that went wrong.
"I have had experience of migrating to Cloud and between different SaaS clouds," he laments.
The hidden costs differ between various delivery model (IaaS to SaaS). Some IT managers do not realise that in IaaS the responsibility to manage operating systems and application still rest on their shoulders.
The cloud provider is here a mere virtual HW provider. Hence the hidden cost for the company is a realisation that the bulk of IT responsible for application integration and possibly for infrastructure management (operating system layer) is still needed.
The same applies to PaaS, he says, but here the CIO is responsible for application integration only.
