Customer migrates COBOL reservation system to microservices on AWS

Amazon Web Services announced that a customer moved its entire COBOL-based central reservation system to microservices on AWS. According to AWS's post, the system now handles 50 million daily availability requests, up from 26 million, with faster response times.

The only source is AWS's own announcement on X, which names no customer, gives no independent measurements, and does not describe how the migration was carried out. The performance figures are AWS's claims and have not been verified by a separate party.
