Wind River Studio is more than StartlingX
StarlingX is a component within the Wind River Studio portfolio, which covers developers (e.g. WR Linux, VxWorks), deployment, operators (e.g. 5G RAN, StarlingX) - basically the whole lifecycle (IoT to backend) - employing digital twins, analytics and advanced security.
I don't want to write an advertisement, you can look up Wind River Studio yourself.
