When you create a Multi-AZ Database Instance using the Amazon Relational Database Service, we automatically create a standby instance which maintains an up-to-date copy of the primary database. If the primary database goes down due to a instance, storage, or network issue, Amazon RDS automatically initiates a failover from primary to secondary and also creates a fresh secondary for you. Here's the basic architecture (see my Multi-AZ blog post for more information):
Today we are making the Multi-AZ deployment model an even better value, with price reductions ranging from 15% to 32%. As an example, here are the old and new On-Demand prices for an m1.small RDS Database Instance running MySQL or Oracle (BYOL) in a Multi-AZ deployment:
| Region | Old Price | New Price | Savings |
| US East (Northern Virginia) |
$0.180 | $0.153 |
15% |
| US West (Northern California) |
$0.230 | $0.167 |
27% |
| US West (Oregon) |
$0.180 | $0.153 |
15% |
| AWS GovCloud (US) |
$0.240 | $0.187 | 22% |
| Europe (Ireland) |
$0.230 | $0.167 | 27% |
| Asia Pacific (Singapore) |
$0.230 | $0.196 | 15% |
| Asia Pacific (Tokyo) |
$0.240 | $0.204 | 15% |
| Asia Pacific (Sydney) |
$0.230 | $0.196 | 15% |
| South America (São Paulo) |
$0.300 | $0.204 | 32% |
This price reduction takes effect February 1, 2013 and represents our continued commitment to make AWS a better and better value over time.

Awesome news, thanks Jeff. Prices seem to be getting lower by the month - soon it might be 0! :)
Prices now updated and live in PlanForCloud
