Magento & Amazon RDS

Hey guys,

We have a Magento shop with some dedicated hardware that we use for both the web application and database. What I'm considering doing is keeping our web application on our own hardware but offloading the database to Amazon RDS.

Even with local replication and daily backups, I'm worried about losing data in the event of some failure. Compound this by the fact that we were just looking through some old database backups and found out that a lot were corrupted. Definitely scared me straight.

So my question is, does anyone think this could create a huge performance hit? I know EC2 to RDS would be ideal but we have a lot invested in hardware and need to continue using it for the time being.

Beyond that, the only other concern I have is the availability of it. I'm a little confused at the pricing and know that most of the time our database runs relatively low on resources... we do maybe 50-100 transactions per day and use very little CPU. However, on new product launches we can do over 1000+ transactions in a 1 or 2 hour period.

My biggest concern is that I don't want the RDS instance I select to hit a ceiling and create issues when spikes like this occur.

Am I misunderstanding something? Can our RDS spike into just about any level of CPU usage without affecting performance (and only increasing my bill)?

Hopefully that makes sense! Thank you for your time!
