Because it's a fully featured public relations platform, not just a "newsdesk" (though that's what it started as some 20 years ago).
We have a main monolithic application at the core. But there are plenty of ancillary applications used to run the various parts of our application (eg. analytics, media monitoring, social media monitoring, journalist databases, media delivery, LLM based content sugestion etc).
Then we have at least one staging deployment for each app (the monolith has multiple). All permutations of apps and environments reach about 50 applications deployed on the platform, all with their own highly available databases (Postgres, Redis, ElasticSearch and soon ClickHouse).
