As a rule of thumb, I normally asume reserved instances are about a third cheaper, which would have a significant impact on the cost analysis. However, even though I do have a number of instances running 24/7, I prefer to have the flexibility and pay the 'extra' money. Each to their own really. Spot instances are also another option: http://aws.amazon.com/ec2/spot-instances/ An excellent point!

Amazon offers both On Demand pricing and Reserved pricing. If you sign up for Reserved you pre-pay for either a one year or three year term; that then lowers your hourly pricing. If you were running a server 24x7 on Amazon you'd obviously go the Reserved route. For high-cpu-medium as of today the On Demand price for 24x7 is: $0.17/h * 24h/d * 30d/m = ~$122/m For high-cpu-medium as of today the Reserved price for 24x7 with a one year term is: $0.06/h * 24h/d * 30d/m + $455/y / 12m/y = ~$81/m Obviously that would have a big impact on your price/performance numbers.

And a query needs to pull large amount of data from the database. This will definitely slows down the Database server. Do you have any idea to Cluster the database server also ? and how can be the database will be update among all individual servers ? Imagine the Database is very large.
