Service Center is resource-intensive. This means production systems should be dedicated to Barracuda RMM. Sharing a server with other applications results in contention for resources, particularly memory and disk throughput, which can significantly impact the performance of all applications on the server.
Memory and disk space requirements listed in this section must be dedicated to Service Center, so additional resources are required for the server operating system and any other roles performed.

Network Load Balancing |

Network Load Balancer
With the implementation of multiple Application Servers, load balancing is required to balance incoming requests across all Application Servers.
Load-balancing is driven by a unique virtual IP address that is typically associated with a specific URL. The hardware servers that will be hosting the content for the virtual IP address or URL will be configured in a server farm associated with the virtual IP address.
There are a number of predictor algorithms that handle the load-balancing. The following two methods can be easily deployed:
- Round Robin is a static load-balancing predictor in which servers receive connections on a strictly rotating basis, ignoring server weight. After a server receives a connection, it moves to the bottom of the connection queue.
- Least Connections is a dynamic load-balancing predictor in which network traffic patterns are considered. The load-balancer determines which server has the fewest connections and then forwards the incoming service request to it.
In order to function as expected the load balancer must be configured to use the persistence method source-address affinity (also known as sticky sessions). Using this method means the load balancer creates a record in memory noting to which server the requests were made for each originating IP address. All future requests from the same originating IP address will be forwarded to the same application server. A timeout may be specified so that these records are not kept forever.

Network Requirements
The following lists the networking requirements for Service Center:
80 TCP inbound Access to the VARAdmin, SCMessaging and SC websites over HTTP.
80 TCP outbound Access to the license server and WSUS meta data server.
443 TCP inbound Access to the VARAdmin, SCMessaging and SC websites over HTTPS.
Firewall exceptions for the SCMonitor.exe and SCworker.exe applications must be made on each application server to allow for communications on all TCP ports where the source IP Addresses are those of the other application servers.
