Daemon's standard FarCry deployment stack is Ubuntu/Tomcat/Lucee/Nginx with MySQL; completely open source.
Railo is dead. Lucee is the Railo CFML engine reborn better than ever before.
FarCry core development is typically done on Lucee and patched for Adobe ColdFusion, so support for Lucee engine is a first class priority. It's worth noting that Daemon is a Member of the Lucee Association Switzerland and is currently the Member representative for President (Geoff Bowers).
You may find some hiccups moving from ACF to Lucee but there is nearly always a workaround with a little bit of refactoring. Some applications "just work" with little or no effort at all.
FarCry Core framework translates seamlessly from MSSQL to MySQL and back again. You are only likely to hit areas that need refactoring with custom queries within your project or plugins.
While we have little if anything to do with Microsoft Azure, we deploy almost exclusively into Amazon AWS through OpsWorks as whole servers or via Tutum (https://www.tutum.co/) as Docker containers.
Lucee is fully supported on Docker with Lucee Dockerfiles available:
And we have sample installs for FarCry projects on Docker for folks to play with:
For example the www.daemon.com.au and www.farcrycore.org websites both run on Docker
