I'm looking at replacing a ( 2 LAMP, 2 Oracle RAC) physical configuration with an Amazon VPC.
I'm thinking of 2 Linux instances where Apache+PHP will be installed and 2 Linux instances where Oracle (or MySQL) would be installed. The Apache instance will fetch their data from the DB. I' also planning to use Amazon load-balancing from "Internet" to both LAMP.
My question is about sharing the storage between both couple. The 2 LAMP would have the same bunch of PHP/HTML/IMG files. The 2 DB should share their storage too.
Is there a way to attach Amazon EBS to a couple of server in the same time (regarding the server just read the data and don't try to write the same bit at the same time)?
