Databases
The Talend Administration Center (TAC) database should be hosted in RDS. RDS provides high availability of the databases and makes it transparent to switch from the master db to the slave db in case the master is not available. Amazon handle the routing of the traffic to the right instance. Having the Talend Administration Center database hosted in RDS will enable us to deploy additional Talend Administration Center and cluster the Talend Administration Center together with the same database for the admin metadata.
