An excellent point! 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:

Thanks for the post!

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 24×7 on Amazon you’d obviously go the Reserved route.

For high-cpu-medium as of today the On Demand price for 24×7 is:

$0.17/h * 24h/d * 30d/m = ~$122/m

For high-cpu-medium as of today the Reserved price for 24×7 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.

Hi Keenan,

The tests here used Redis 1.0.2. However, I also did the same tests using the version straight from Git and the results were essentially the same.

This is great. What version of redis did you run? (1.01 or head ~1.1)?

Thanks
