Exploring AWS RDS for SQL Server vs Azure SQL

I’m looking at moving to AWS RDS for SQL from Azure SQL. The biggest downside is the licensing.

Currently, I’m using a SQL Pool using the DTU model with 50/eDTUs (Standard Budget Friendly). That runs about $110/month, where 5 DBs share the resources.

On AWS RDS for SQL Server
db.t3.xlarge
vCPU: 4
Memory: 16 GiB

Edition: Express
$266.00/month
reserved: $171.66/month

Edition: Web
$302.50/month
reserved: $194.39/month

Edition: Standard
$772.62/month
reserved: $730.72/month

Changing to a vCore Model using Elastic Pool

Azure doesn’t provide the memory spec, but it’s 5.1 GB per vCore

vCore:2
Memory: 10.2 GB
$375.66/month

vCore: 4
Memory: 20.4 GB
$743.85/month
