I have a client using SQL Server for everything, including powering marketing dashboards using analytics queries. They are excited to start pushing data into Redshift as a data warehouse for the speed improvements alone (eg queries that take hours now take minutes or seconds). But they want to compare cost.
I'm a bit naive how to do this, since these are very different tools, like saying I'm nervous about the cost of a flight compared to using my bicycle around town.
What's the best framework and pricing data to share to do a realistic comparison?
