That 47% discount is a discount on AWS on demand (EC2/RDS) prices - not a 47% discount relative to GCP sustained use pricing.

I just finished researching pricing on AWS/GCP for my team - and I found that generally AWS matches GCP pricing (sometimes a little higher, sometimes a little lower) if you can commit to 1 year.

From what I found through my research, the only way to achieve a significant reduction in price relative to GCP is if you can commit to 3 years on AWS.

However, I found it somewhat difficult to compare apples to apples - as it can be difficult to match CPU and RAM - I had to settle for close enough. There is a very big difference in network bandwidth allowances per type - with GCP being far more generous. Load balancing offerings differ greatly - with GCP seeming much more modern in design (HA, geo-load balancing, anycast static ip, etc.). My point here being that our analysis took into account price as well as other factors.
