Back in 1998 one of the reasons my boss back then used for not doing something on a Linux box was
"We don't have enough people with the skills to support that"
Fast forward 10 years and the opposite is happening,
I had a chat with a coworker the other day and we were wondering how we ended up having a windows box from a 3rd party vendor in our platform since no one in our organization knows how to support it.
I imagine similar conversations in MySQL environments where people wonder who is going to support that one proprietary database that came a long with an oldskool vendor
Evolution and Adoption is happening, change happens !!
