Load balancers and CDN

With a cluster in a LB configuration, the computationally intensive requests are divided between the different nodes in a network. There is a separate unit that takes care of checking the criteria on the individual computer nodes and divides the requests accordingly, the so-called load balancer or load distributor.

Such a cluster becomes a prerequisite if a large number of parallel activities are expected that cannot be managed by one device alone. It is therefore recommended to use it in the same way as in an HA configuration for the following services:

• Web server and web services with nginx, Apache, litespeed, nodejs, Tomcat, Jboss
• Encoding and streaming
• Datebases like MySQL, MariaDB, PostgreSQL
