Scaling MySQL with TCP Load Balancing and Galera Cluster We introduced TCP load balancing in NGINX Plus R5, and have continually added features in subsequent releases, as well as support for UDP load balancing. In this article we explore the key requirements for TCP load balancing and how NGINX Plus addresses them. To explore the features of NGINX Plus we will use a simple test environment that represents the key components of an application with a scaled database backend. For complete instructions on building the test environment, see Appendix 1. The test environment for load balancing MySQL nodes In this environment NGINX Plus acts as a reverse proxy for the database server, listening on the default MySQL port of 3306. This provides a simple interface to the client, while the backend MySQL nodes can be scaled out (and even taken offline) without affecting the client in any [ more… ]
