How it works
A load balanced system requires at least two installed web servers with an upstream load balancer. The JobServer web application has to be installed on all web servers and the central directories (e.g. the uploads directory) have to be set up on a file server available to all web servers. This file server should also be installed fail-safe.
Next to files, JobRouter saves all instance data in the database. This means the database server has to be fail-safe, too.
Any amount of web servers can be installed.
If a user calls JobRouter via the address of the load balancer, he will be automatically redirected to one of the web servers. The JobRouter web application installed on the respective web server processes the request of the user and establishes a connection to the central database. There he can find the paths to the central directories and can then access all central files next to the local files of the web server.
