Object Relationships
Most contexts in the CLI correspond to an Equalizer object --
servers
,
server instances
,
server pools
,
clusters
,
match rules
,
responders, CRLs, certificates.
The following diagram shows the relationships
among these objects.
On Equalizer, a
server
corresponds to a real server hosting an application behind Equalizer. Each
server has an IP address that Equalizer uses to send client requests to the server. This IP address
is sometimes called a “real IP” because it corresponds to a real server.
A server must be assigned to a
server pool
before it can be associated with a cluster. When you
assign a server to a server pool, you create a
server instance
of that server in the server pool. The
server instance definition specifies operating parameters for the real server that are effective
only within that server pool. This allows you the flexibility to associate a single physical server
with multiple server pools, and set different server instance options within each server pool.
A server pool in turn is assigned to a
cluster
. Client requests are sent to a cluster IP address (often
called a “virtual IP”) assigned to Equalizer and then routed to the server pool instance selected by
the load balancing algorithm and other options. In all clusters, a server pool is assigned directly to
the cluster. For Layer 7 clusters, additional alternate server pools, as well as other objects and
options, can be assigned to one or more
match rules
.
