A web farm is a group of two or more servers used to host the same site. Web farms increase the capacity of a web site, and improve availability by providing fail-over. Web farms are universally used for high-traffic and mission critical web sites.
When an application is hosted by несколько процессов на одном сервере говорят, что это веб-сад environment.
A web farm scales across multiple servers. A web garden scales across multiple processors.
from this page:
A web farm is a multi-server scenario. So we may have a server in each state of US
If the load on one server is in excess then the other servers step in to bear the
brunt. How they bear it is based on various models.
1. RoundRobin. (All servers share load equally)
2. NLB (economical)
3. HLB (expensive but can scale up to 8192 servers)
4. Hybrid (of 2 and 3).
5. CLB (Component load balancer).
A web garden is a multi-processor setup. i.e., a single server (not like the
multi server above).
