When I look at the oil & gas sector, I remember MS-DOS + Wordperfect was the beginning. Then Windows 3.1 + Microsoft Office took over, and since that, its been Microsoft, Azure, and SAP.

They refuse Google Cloud, AWS, and many still believe open-source is cancer. They are Microsofts best customers. They prefer consultants over hiring software developers, and the consultants just to what they're told and never question the status quo.

Whenever I spending time at these companies, my head is filled with dinosaurs.

Where I live we have something called The ONS event/Exhibition, where the oil sector gathers to promote themself. 2 years ago AWS had a big stand there, but it was mostly empty. This year, AWS doesn't participate at all.
