Acronyms and terminology:
SLB : Server Load Balancing
When a client initiates a connection to
virtual server, the system load balances
the connection to the chosen real server
based on the user configuration.
SLB is important for Scaling of Web
Services and for traditional serverices
such as DNS, FTP etc.
Server Farm : Contains cluster of Real Server
Virtual Server : Group of Real Servers
RServer : RServers are physical devices that
do not belong to any server farm.
Real Server : Real Servers are physical devices
assigned to a server farms.
Real servers provide services that
are load balanced.
Health Probe : The mechanisms to monitor the health
of real servers.
sticky ConnectIons : Sticky connections limit traffic
to the individual real servers by allowing
multiple connections from the same client
to stick (or attach) to the same real
server using source IP addresses,
source IP subnets, cookies, and the
secure socket layer (SSL) or by
redirecting these connections using
Hypertext Transfer Protocol (HTTP)
redirect messages. Sticky connection
feature also permits coupling of the
services that are handled by more
than one virtual server.
cookie : A cookie is a small data structure used by a
server to deliver data to a Web client and
request that the client store the information.
In certain applications, the client returns
the information to the server to maintain
the state between the client and the server.
