The most important consideration when choosing an operating system is:
What the computer will do
The licensing model of the operating system
The operating system’s mascot
How much performance is needed
Whether or not it is cloudfriendly
Linux is not Unix because:
It’s not good enough
It’s free
It’s not made by the Open Group
There are too many distributions
It hasn’t undergone certification
A release cycle:
Is always 6 months
Doesn’t matter in an Open Source environment
Describes how long the software will be supported for
Describes how often updates to the software come out
Only applies to software you pay for
A maintenance cycle:
Should be long so that you have time before you need to upgrade
Only has meaning for paid software
Should be short so you always have the freshest releases
Describes how often updates for software come out
Describes how long a version of software will be supported
