Advanced Deployment

The document discusses advanced deployment strategies for Rails applications. It covers using background processing and search services to improve performance. It also discusses options for scaling databases, such as read slaves, master-master replication, and data partitioning. For applications with multiple clients, it recommends configuring clients differently but keeping the same codebase and database structure. When deploying to cloud infrastructure, it advises using a central directory service to dynamically configure database connections. Throughout, it emphasizes that simpler solutions are generally better than complex ones.
