Almost all of this software is open source, which makes the business unusual. Anyone can download it for free, so the companies here sell subscriptions, support and the hard engineering that keeps it running. India is one of the main places that engineering is done. Red Hat and Canonical have made India one of their largest engineering bases anywhere, Red Hat mostly in Pune and Bengaluru, and Nutanix, Wind River and Azul build here too.
For an engineer, this is work on the software other software depends on.
