Let's do the math:
A 64GB instance in Azure is $156.28/month reserved. That's $2.44/GB/month.
Let's say you use an extra 4GB RAM for a safety margin or laziness, and you have 50 replicas. That's $488.375 per month 'wasted'. Or $5860/year.
You'll never recoup the money it takes to get those replicas perfectly sized. Just give every app 4GB more RAM than you think it needs, and move on with your life.
- wozzio 10mo agoIf you're small startup burning $5k/year in lazy tax is smarter than distracting your engineers the math flips when you hit scale. For some that safety margin isn't small. At a certain volume, waste exceeds the cost of a full-time engineer so optimizing becomes profit.
- esseph 10mo agoYou have to pay for that ram, which, by the way, is under a giant cost premium right now. Multiple the number of apps by the number of desired replicas, across the number of clusters, etc. you could easily be paying 2x-3x in pricing tiers.
