This is where the product stands apart. You do not need to set up thousands of servers, hundreds of database, and hundreds of DBAs. You need to set up a minimal infrastructure. There is no need to pay upfront the cost of an entire data center. It is pay as-you-go. Therefore, you realize the benefits and scale up/down as needed. Amazon will provide the required capacity. This will help you to realize the ROI quickly, which helps you to keep on growing.

This has helped reduce the cost at the same time increasing the agility of the organization. Some thing which would have costed millions of dollars and nine DBAs could easily be replaced by Amazon RDS.
