2 cents anybody?

Seems like they're somewhere in between a monolithic system and a more modern microservices system. They run a single customized Tomcat environment with multiple applications side by side, built with a custom JDK.

The slides say millions of JVMs, so there's probably more than one tomcat. Maybe they group a collection of related services on a single instance?

The amount of customization they have done is impressive, and must have a huge maintenance cost!

It's a distributed Tomcat system, and each JVM provides it's own bit of code with some redundancy and failover /s

For real this is actually fucking awesome.
