Last employer is banking. They have a multi year investment in moving various workloads, from VM compute to lambda to container, into multi region, multi cloud environments. Dozens of dev, sec, and ops people working together to make provisioning seamless and safe, code deploys done through CI. When you make that kind of decision, going back or altering course is a similar multi year decision. Going cloud native at a cost of tens of millions in billing and labor specialty means you have lost or reprovisioned other specialties, haven’t renewed on premise equipment, and so on. These companies are like supertankers, not racing yachts. Take a long time to alter course.
