The Cloud is the best thing that has happened to IT.
As an IT Network engineer, I have experienced the flaws of a slow and inflexible IT department. This is most of the reasons we find a lot of the corporate IT staff shaking in their boots!
The Cloud has offered an alternative to Management, but they are having a hard time understanding the Pro's & Con's to migrating services. Is a simple decision, get on the cloud and cut the excess fat of useless IT personnel and outdated equipment.
There are some IT guys who will not feel secure without a steady paycheck... but in fact is just the opposite for the professional IT mind, this can be simply an opportunity to thrive if you are truly an asset in knowledge and experience.
If you are in IT, and you are worried about your job. Is only a matter of time before your worry becomes a reality. Instead, stop worrying and start moonlighting and you will find there is a lot of demand and opportunity if you have a value to offer. If you don't... switch to management.
