We are in the process of migrating Tomcat and MySQL to Microsoft Azure Cloud and facing challenges due to the dynamic nature of the cloud like allocation of dynamic ip and ports to the instances of Tomcat & MySQL in Azure. Because of this behavior Tomcat needs to
1) Dynamically update the ip and ports of the different MySQL instances in the JDBC URL ( http://dev.mysql.com/doc/refman/5.5/en/connector-j-reference-replication-connection.html). Suppose the following is the JDBC URL, then it has to be updated in Tomcat at run-time when a new instance of MySQL is bought up or an instance of MySQL is bought down. url=jdbc:mysql:replication://127.0.0.1:5104,127.0.0.1:5108,127.0.0.1:5112, 127.0.0.1:5116,127.0.0.1:5116/itops 2) We are using DBCP (http://commons.apache.org/dbcp/) for connection pooling. Similarly when a new instance of MySQL is bought up or an instance of MySQL is bought down the pool has to be updated dynamically accordingly at run-time. Has anyone come across a solution for these problems while deploying Tomcat and MySQL in Cloud? Thanks, Praveen
