Let’s assume you currently have a MySQL Setup with one “Master” and multiple “Slaves”, and you do want to make sure your Sugar system uses the “Slave” instances for reading purposes. Alternatively, if you are looking at deploying MySQL Master/Slave instances with a click of a button to test this out, you can achieve the same setup using Amazon AWS RDS, by deploying one MySQL database with additional read replicas.
SugarCRM commercial editions already have a feature that allows to connect Sugar to a slave database for Reports and/or an additional one for module’s ListViews, providing additional performance and scalability to the application. The feature is provided out of the box and it is available by changing a configuration file, for self hosted systems.
