To be fair, the post show that about 2/3rds of that spend is from the decision to run twice the needed capacity to be able to do green blue deployments, and to cloud host their metabase analytics.
And it explains there's currently zero revenue.
So it seems fair to judge the situation there based off those pieces of information we've been given.
As I posted elsewhere, the OP's choice to run dual redundant green/blue capable instances and cloud hosted metabase might have good reasons, but right now those reasons are not "wanting a HA solution so revenue isn't impacted"...
That's not how green/blue deployments work. You don't keep both colors up unless you have completely failed to understand the concept.
Green/Blue is all about saving resources and costs, not keeping them around. You misread the cause here. It has nothing to do with deployment strategies.
That's not how I read what the OP's doing in the article. Sure, maybe he's not doing "proper blue/green", but that is what he uses to explain running a duplicated pair of web/app servers full time...
