Hi James, I paste you from the official documentation: http://www.zenloadbalancer.com/zlb-administration-guide-v305/#MANAGEFARMS_SECTION
*Profile:* Define the type of farm and load balancing method for the new farm. You could choose one of the following profiles: *TCP*: It’s a simple load balancing that delivers traffic in raw TCP data at application layer (layer 7). The basic mechanism is about open 2 sockets for every connection, one to the client and other to the real server, and then delivers the raw data between them. The selection of this method could be adecuated for protocols like SMTP, RDP, IMAP, LDAP, SSH, etc. *This profile is marked as obsolete, use the L4 profile farms instead. In order to configure this farm profile, a virtual IP address and a virtual TCP port will be required.* *UDP*: It’s a simple load balancing that delivers traffic in raw UDP data at application layer (layer 7). The basic mechanism is about open 2 sockets for every connection, one to the client and other to the real server, and then delivers the raw data between them. The selection of this method could be adecuated for protocols like DNS, NTP, TFTP, BOOTP, SNMP, etc. *This profile is marked as obsolete, use the L4 profile farms instead. In order to configure this farm profile, a virtual IP address and a virtual UDP port will be required.* *HTTP*: It’s an advanced HTTP layer 7 load balancing (or Application Delivery Controller) with proxy special properties. It’s included in this profile features like HTTPS layer 7 load balancing combinated with SSL offload acceleration This profile is adecuated for web services (web application servers included) and all application protocols based on HTTP and HTTPS protocols like WebDav, RDP over HTTP, ICA over HTTP, etc. In order to configure this farm profile, a virtual IP address and a virtual TCP port will be required. *L4xNAT*: It’s an high performance load balancing system at routing layer 4 which combines multiples of load balancing methods like Source NAT and Destination NAT. This profile could handle any kind of protocols like TCP, UDP, ICMP, etc, and all protocols based on them. In order to configure this farm profile, a virtual IP address will be required. Later, in the main farm configuration, it’s possible to specify a TCP or UDP protocol and a port o port range. *DATALINK*: It’s a routing load balancing system at layer3 which balances the load through routes across different networks allowing to balance routers uplink accesses to internet. This is a protocol agnostic load balancing method. In order to configure this farm profile, a virtual IP address will be required. SO if you want to load balance in base to virtualhosts, URIs, to work with persistence session for cookies, to configure ssl offload, etc.. then you have to use the specified profile HTTP, in other cases use TCP profile. The HTTP profile is a more advanced profile ready for web services.
