> Perhaps but it's only been in the last few years that I've been hearing about it, mostly WRT the cloud vendors (AWS, specifically). As business have become more willing to move core services to cloud platforms, they've demanded that those platforms provide a single sign on solution that integrates with their corporate directory. So, the popularity of SAML has certainly risen with the popularity of cloud / SaaS, but it's perfectly normal for a technology to become more popular with time (until it eventually goes into decline), and that increase in popularity means that it becomes more widely known, and some people who have never had to deal with it before, now come into contact with it. I've been involved in SAML implementations at fairly conservative technology organisations (banks, pharma) for more than 6 years (and for most of that time it wasn't my core role). It's old tech, that's in wide usage, it just isn't something that most people need to deal with because it's boring identity management infrastructure that most application developers don't get involved in.
