The LRZ offers institutions the use of a virtual server via a load balancing system. Load balancers are able to distribute traffic via a service address to different server systems. They allow to distribute the arising load (load balancing) but also to increase the availability by increasing the redundancy. By using several virtual machines behind an SLB it is possible, for example, to carry out software updates on the machines without service interruptions.
Scope of Services and Service Specifics
The SLB service includes an IPv4 and an IPv6 address and the switching of http (port 80) and https (port 443) traffic.
