I am suggesting implementation of an EDUCATION portal of considerable size on Joomla with the CMS as the source of information on the portal. I will also be using an ESB to connect to various other backend applications to bring data to forefront on the portal.
How can I determine -
1) The Size of MySQL Database I need for the portal and CMS only?
2) The number of databases required for 24/7 availability?
3) How many Databases per instance - Dev, Test and Production?
